Posted on January 29, 2022April 28, 2025 by Martin Mora

In the diamond world, there are many different cuts to consider before buying. Every different cut signifies different aspects of a diamond and you need to explore every cut in detail before you make a final choice. The Asscher cut diamond is considered to be one of the most symmetrical and eye-pleasing cuts in the world of diamonds.

If you’re someone who has been exploring cuts for pure diamond engagement rings for a significant diamond pendant then this article is perfect for you to understand what an Asscher cut is and what are the different aspects of the Asscher cut.

What is Asscher Cut Diamond?

The Asscher cut diamond has 8 edges and hence is often known as the octagonal diamond as well. The main identifying features of an acid cut are it is square in shape and has a significantly small table. All the facets of the diamond are rectangular in shape and this is what gives the effect inside the diamond.

The Asscher cut is also known as a step-cut diamond because the diamond is cut at different levels exactly like a staircase. The diamond is also often compared to the emerald cut and the Princess cut because of its shape and similarity in cutting style.

There are two types of Asscher cut diamond 1 is the classic Asscher cut which has 58 facets and the other one is known as the Royal Asscher cut diamond which has 74 facets. Both these cuts are identified as having a tall crown and a deep pavilion.

History of Asscher Cut Diamonds

The Asscher cut diamond is named after its founders which were the Astor brothers and specifically the diamond is named after Joseph Aster who founded the cut. The diamond cut is only 120 years old and was discovered in the early 1900s.

The Asscher cut diamond became super popular very early after its conception because in 1920 the art deco period started which is an era that was popular for geometrical and symmetrical pieces of art. Many say that the popularity of the Asscher court was heavily influenced by the ongoing industrial revolution.

Geometry and Modernity were seen as a sign of prosperity and the Asscher cut which is highly symmetrical of course gained popularity in terms of design.

Till today as Asscher cut diamonds are considered an elegant choice because of their unique cut. Throughout history, lab grown Asscher diamonds, which are the favorite of the royal families around the world and are still the highlight of many historical pieces.

Length to Width Ratio of Asscher Cut Diamond

The Asscher cut is known for its symmetry and geometric appearance. The best ratio is 1.00-1.05 when it comes to the Asscher cut.

A ratio of 1.05-1.10 is considered the second-best side-to-side ratio for an Asscher cut. A 1.10-1.15 ratio is considered poor but if you have no other option, you can consider this as the last resort.

What Makes Asscher Cut Diamonds a Great Choice?

Other than its appearance, lab created Asscher cut diamond offers a lot of other plus points that make them worth their price.

– They are a perfect blend of emerald cut diamond’s elegance and brilliance of a princess cut diamond, which makes these Asscher cut diamonds quite unique and one of a kind.

– In proper settings, Asscher lab diamonds may look bigger for their carat value. This can be further enhanced by adding a halo around the center diamond. Hence you could end up with a much bigger diamond compared to the price range.

– Asscher cut diamonds have a clean, neat, fine, and elegant look. Their perfect blend of vintage and modern makes them quite an excellent choice for any piece of jewelry, especially an engagement ring.

– Due to their large facets and tables, the body color is easily refracted from within the Asscher diamond. This makes the lab grown asscher cut diamond perfect for every skin tone. Coupling the warmer-hued diamonds with yellow gold or rose gold might just enhance its vintage and timeless appeal. By going for white gold or platinum with a colorless diamond, the overall look may appear very elegant and sophisticated to anyone who would look at it.

– Asscher cut diamonds are one of the most affordable diamond cuts. Since the amount of wastage that occurs while the diamond is cut is very low, it also makes the price of the diamond drop. If you’d like to make the diamond even more affordable, you can go for lab-grown diamonds. They are real diamonds that are manufactured synthetically in machines.

Asscher as mentioned before are highly symmetrical and have a lot of texture in themselves already. This is also the reason why simple settings are considered best for Asscher cut diamonds. If you are someone looking for an engagement ring setting for Asscher cut diamonds we suggest you go with pave set bands and a 6-prong or a 4 Prong solitaire setting.

Asscher cut diamonds look best with white gold and platinum bands because they enhance the brilliance of the Asscher cut. Simple small diamond accents in a pave setting or a gypsy set band look great. You can also opt for Asscher cut diamond in a Halo setting where the central diamond is complemented by a fancy colored diamond like a green diamond or maybe another precious stone.

When it comes to fancier setting variations designs in the band itself are our favorite. Small engravings on the band look minimal and do not take the spotlight away from the diamond itself.

Another few setting variations you can go for are old vintage art deco designs. Since the Asscher cut was the highlight of the Art Deco era, these designs complement the cut beautifully. The three diamond ring with trapeze-shaped diamond accents is a great design.

Another famous design from the Art Deco age would be the Jessyca ring design which features a big Asscher cut Centra diamond, multiple types of diamond accents, and an intricate grain design on a platinum band.

Wearing an Asscher cut diamond ring on finger adds an air of timeless elegance, as the distinct facets of the diamond catch the light and exude a subtle yet captivating sparkle.

How Big Can Lab Grown Diamond Get?

Posted on January 29, 2022May 27, 2025 by Martin Mora

Diamonds are always going to be a woman’s best friend. From purchasing them for no specific reason to celebrating the most important days of one’s life with the gems, diamonds are going to stay in trend and people’s hearts for as long as we have occasions to celebrate.

But are people aware of the impact that the mining of diamonds creates on our planet’s internal environment and ecosystem? Most diamond shoppers tend to simply concentrate on the bling and sparkle that diamonds bring along and ignore the harm it causes to our planet since the process of mining diamonds is in reality highly detrimental for our planet.

Digging into the earth for miles to get access to a handful of diamonds creates many disadvantageous side effects to our planet’s natural resources since the soil, water, and air surrounding the site from where diamonds are mined get heavily polluted. A large amount of soil and other natural resources have to be removed from mining sites which leads to a massive depletion in natural land resources.
But as mentioned before, diamonds share a special relationship with most people wherein the attachment between them is hard to maim. And hence, scientists and diamond jewelers have made an excellent effort at battling this issue wherein a new type of diamonds have been invested.

Grown in labs, the lab-grown diamonds, have minimal to no impact on the earth’s environment and are the perfect choice for customers who love our planet and diamonds alike!

How Lab-Created Diamonds are made

Lab-created diamonds are diamonds that resemble real stones based on most of the aspects such as the optical, physical, and chemical properties. The only major difference between the two is their source of origin.

Real diamonds are created under extreme conditions inside the earth’s crust and take a time period of around millions of years to form. The stimulus needed for their creation is naturally provided by our planet and we are merely discovering their existence by digging and mining

Lab-created diamonds however are made by men through the process of replication in a controlled environment of the earth’s natural growth processes. This leads to the formation of pure carbon raw diamonds that are practically identical to the earth mined diamonds.

The grading of such diamonds is also done by the same expert and reputable gemological institutes that provide their services for the grading of natural diamonds.

Methods for Growing Lab-Grown Diamonds

Two methods can be used to create lab-grown diamonds.

Chemical Vapor Deposition (CVD)

Through this method, natural diamond particles are used to build a diamond wherein the particles are positioned in a CVD machine. The machine is then filled with carbon gas and the temperature is hiked to extreme limits for the particles to get heated. The high temperature and pressure from gas lead to the breaking down of the carbon molecules in the particle. Then the molecules vaporize and bind to the diamond seed forming various layers until a larger diamond of the desired size and carat weight is formed.

High-Pressure High Temperature (HTPT)

This particular technique uses an HPHT machine and diamond seed to form a lab-grown diamond. The HPHT machine is filled with pure carbon and extreme heat with pressure is applied to melt the carbon. The rough diamond starts forming around the seed and eventually forms enough amount according to the desired size and carat weight.

Through either method, the diamonds grown are rough diamonds that are cut, polished, and mounted on bands by various cutters and designers to form the different forms of jewelry.

Do the Methods of Growing a Diamond Affect its Size?

If we talk about the most commonly used process to grow a diamond it is High-Pressure High Temperature (HPHT). It has been around for the longest. However, Chemical Vapor Deposition (CVD) is a method that has been termed to be more effective and has been in the market and demand for quite some time.

At once the most reliable method was considered to be HPHT as it could make your diamond grow exceedingly large, that is up to 10 carats. On the other hand, let us also remind you that the market for lab-grown diamonds with their technology is quite competitive and changing every day.

Through the recent years, CVD as a method has grown a great deal of market reputation. It has done this by also increasing its production proportion range, it went from producing 6-carat diamonds to 9-carat diamonds. Even the largest lab-grown diamond has a 155-carat disc which was done through CVD.

In some ways HPHT does have an edge over CVD, that is because of the carat size both the processes make. The size that HPHT produces is a whooping 10 carat, and in front of it, a maximum 9-carat diamond produced by the CVD process is something that makes it fall back a little.

Though if we look at any other factor, both methods are incredibly effective to make a large lab-grown diamond. Keeping in mind the size producing capabilities, let us remind you it only seems to be growing with advancing technology.

Given how technology is growing, there is no margin as to how large a lab-grown diamond can get. This also means that buyers will have a lot of sizes to pick from and that is a plus in itself. Lastly, the size of the lab-grown diamond largely depends on the time invested to grow it.

Large Diamonds vs Small or Medium Diamonds: What takes Longer to Grow?

The time taken to grow a lab-grown diamond can be a few weeks, on the other hand, natural diamonds take millions of years. The time taken in the lab for a diamond to grow however is influenced by the technique used for its growing.

HPHT is a technique that uses an extreme amount of pressure to grow a diamond. The pressure applied shall be altered as and when the size of the diamond grows. What it looks like visually is like trying to compress a tiny pebble. However, in this process, that pebble grows into a larger and larger rock.

To grow a large diamond is a very systematic process. And the lab in this setting is the perfect environment to include the process of this growth. A medium-size diamond in the lab will relatively take only a few weeks to grow, however, a large diamond needs more time and attention (a few months).

However, all of this makes one thing clear: there is a huge array of options in terms of size when you go to choose a lab-grown diamond.

Conclusion

Hence, lab-created diamonds are the most suitable option for people who want to avoid leaving a carbon footprint on our planet but still want the effect and brilliance of a real diamond. The lab-grown diamonds offer the same amount of durability and genuineness as the real ones do and so can be chosen by customers to decorate their outfits on special occasions including something as special as an engagement or a wedding, with the bonus being the much lower prices at which the lab-grown diamond jewelry is available at.

CVD Diamonds: All That You Need to Know

Posted on January 29, 2022March 13, 2024 by Martin Mora

CVD diamonds, This come may be met with a blank if you mention it to someone outside the diamond industry. There are not a lot of people who know what the acronym stands for or what exactly these diamonds look like. This is unfortunate because, for anyone who wants a diamond without the ethical and environmental issues that come with mined diamonds, these stones are perfect. Not to mention the fact that they caused a fraction of what natural diamonds do.

To help you understand the manufacturing process, properties, cost, and a lot more about these diamonds, we have curated this handy guide. Before buying a CVD diamond ring or an engagement ring, it might be worth looking into lab grown CVD diamonds.

CVD is an acronym for chemical vapor deposition. Essentially, it refers to the process in which certain materials are deposited when a gas acts upon a substrate. The process involves some chemical reactions that lead to the deposition of the material.

What is CVD Diamond?

Diamonds can be classified into two types depending on the formation process. They formed under the earth’s surface and took billions of years of heat and pressure to form, they are known as natural mined diamonds.

On the other hand, man-made diamonds are formed on the surface of the earth, and as the name indicates, synthetically. One type of man-made or lab-grown diamond is the diamond’s CVD, which is made in labs by using a special process called chemical vapor deposition.

Characteristics of a CVD Diamond

CVD diamonds mirror the precise attributes of natural diamonds, sharing identical internal structure, chemical composition, and captivating luster. Just like their natural counterparts, CVD diamonds boast remarkable durability, scoring a perfect 10 on the Mohs scale of hardness, and exhibit stunning brilliance and sparkle.

Although distinguishing a lab-created CVD diamond from a natural diamond of similar quality is nearly impossible, it’s crucial to be aware that CVD diamonds may sometimes exhibit less desirable traits such as brown tints and internal graining, necessitating post-growth treatment. In comparison, HPHT lab-created diamonds tend to be of higher quality than CVD diamonds.

[blog_page_inventory shape=”Oval,Emerald,Princess,Radiant,round,pear,cushion,kite,rose cut,old mine,marquis,hexagon” carat=”1.80,3.10″ cut=”0,4″ color=”0,10″ clarity=”0,11″ dtype=”CVD”]
[blog_page_btn title=”Buy Lab Grown Diamonds” url=”https://www.loosegrowndiamond.com/inventory/”]

Similar to natural diamonds, CVD diamonds undergo grading based on cut, color, clarity, and carat weight. Despite being engineered by humans, CVD diamonds share vulnerabilities with natural diamonds, potentially acquiring color tints and internal flaws during growth. Finding flawlessly clear CVD diamonds is exceptionally rare – some may be heavily included and poorly colored, while others may be nearly colorless with only minuscule imperfections, much like their natural counterparts. Opt for diamonds graded between SI1 and VS1 for clarity, and D to F for color, ensuring top-notch quality and value for your investment.

Remarkably, even seasoned gemologists struggle to differentiate between CVD diamonds and natural diamonds because CVD diamonds possess identical chemical, physical, and optical properties, including the same flaws. When purchasing a CVD diamond, its origin is specified on the GIA, GCAL, or IGI certification. Beyond this certification, specialized laboratory equipment is necessary to distinguish a CVD diamond as a product of human creation.

Chemical Vapour Deposition (CVD) Diamond Making Process:

Diamond Seed Selection:
- Choose a thin diamond seed, typically a 300-micron thick, 10x10mm slice known as a ‘diamond seed.’
- Thoroughly clean the diamond seed to prevent crystallization of trace elements or imperfections during growth.
Sealed Chamber Setup:
- Place the cleaned diamond seed into a sealed chamber.
- Heat the chamber to approximately 800°C.
Carbon-Rich Gas Influx:
- Flood the sealed chamber with carbon-rich gas.
- Ensure a completely sealed chamber to prevent the entry of other gases, disrupting diamond growth.
Ionization and Attachment:
- Under intense heat, the carbon-rich gas ionizes, breaking down into pure carbon molecules.
- These pure carbon molecules attach to the original diamond seed.
Crystallization Process:
- Repeat the process, allowing the carbon molecules to bond and build upon the existing diamond seed.
- Continue until a fully formed, rough diamond is created.
Efficient Growth:
- CVD diamond creation employs a highly specialized scientific process perfected over decades.
- Adapts the chemical vapor deposition process, commonly used in the semiconductor industry, to efficiently produce jewelry-quality diamonds in two to four weeks.
Potential Traits and Post-Growth Treatment:
- Rapid CVD diamond growth may lead to less desirable traits such as graining, spotty inclusions, and brown tints.
- Post-growth High-Pressure High-Temperature (HPHT) treatment can remove or improve these traits, enhancing the diamond’s overall appearance but may cause milkiness.
- Ideal to seek a CVD diamond without post-growth treatment, as indicated on the diamond’s certificate.

CVD vs HPHT Diamonds

When it comes to creating diamonds, there are two main methods: HPHT (High-Pressure High Temperature) and CVD (Chemical Vapour Deposition).

HPHT diamonds mimic the natural diamond formation process that takes millions of years in the earth’s depths, using high pressure and temperature. This method, unlike CVD, doesn’t involve gas. While both HPHT and CVD diamonds take only a few weeks to form, HPHT requires more energy. Generally, experts note that HPHT diamonds tend to have higher quality and less often need additional treatments after growth.

The key dissimilarity between rough CVD and HPHT diamonds lies in their shapes. CVD diamonds grow in a cubic shape, whereas HPHT diamonds take on a cuboctahedral form. Although distinguishing between the two requires a trained eye, this difference in structure is noteworthy.

Some laboratories adopt a combined approach, starting with the less energy-intensive CVD process and finishing with HPHT. This hybrid method is chosen because HPHT can enhance clarity and color. Importantly, chemically, physically, and optically, both CVD and HPHT diamonds are identical to natural diamonds.

Are CVD Diamonds Affordable?

In the realm of diamonds, affordability is a relative concept. Generally, lab grown CVD diamonds come with a lower price tag compared to mined diamonds—around 20–30% less.

For the amount you’d invest in a 1.5-carat mined diamond, you could opt for an upgraded 2-carat CVD diamond instead. This cost difference can be attributed to three main factors:

The substantial expense is tied to excavating deep holes in the Earth.
The extensive supply chain involved in dealing with mined diamonds.
The historical manipulation of pricing within the industry.

The journey of natural diamonds involves intricate processes: locating and extracting them from the ground or seabed floor, shipping them to cutters, wholesalers, and jewelry fabricators, and distributing them through various channels, including independent retailers and large diamond chains with hefty rents and advertising budgets.

In contrast, CVD diamonds sidestep much of this complexity, resulting in a more budget-friendly price. Despite their lower cost, it’s crucial to recognize that CVD diamonds still hold significant value—they are, after all, diamonds in every sense of the word.

Frequently Asked Questions (FAQs)

Why is it Difficult to Synthesize Diamonds in the Lab?

Diamonds are made up of carbon, just like coal and graphite. The only difference between these materials is the arrangement of the carbon atoms command which is also known as the crystal lattice. It is difficult to synthesize CVD diamonds because graphite is one of the most stable forms of all types of carbon. That is why diamonds also occur very rarely in nature.

Earlier, in the 1950s, graphite was converted into diamonds using the high pressure and high temperature technique, also known as HPHT. This was a very difficult way to synthesize diamonds in the lab as the stability of graphite would prevent the formation of diamonds using this technique. However, with the introduction of the CVD technique, it was possible to deposit carbon atoms on a surface using a gas that contained carbon.

If proper techniques are used, it is possible to enhance the growth of diamond crystals and suppress the growth of graphite crystals.

How are CVD Diamonds Made?

This technique involves using atomic hydrogen on graphite to turn it into diamonds.

Hydrogen is usually found in nature as hydrogen molecules, which are formed by combining two atoms of hydrogen together. To make CVD diamonds, we first need to break the molecular hydrogen into atomic hydrogen. This is done by using a gas activating agent, which could be an intense plasma or a hot filament.

After hydrogen gas is dissociated into its atoms, the next step is to slowly apply it to the substrate, that is graphite. Hydrogen selectively etches the surface of graphite and breaks up the double bonds. This converts the graphite bonds into diamond bonds.

This is done by first placing a thin seed diamond in a sealed chamber and subjecting the seed to high temperatures, usually around 800 degrees Celsius.

After that, hydrogen, or a mixture of carbon-rich gases which includes hydrogen and methane, is introduced into the chamber. Using the methods stated above, the gases are ionized and their molecular bonds are broken. This results in the attachment of pure carbon to the diamond seed. As more and more carbon atoms are formed, they develop atomic bonds with the same diamond.

What are the Substrate Materials that can be Used?

Diamond can be deposited on various types of materials. Most of the time the seed used is a piece of the diamond itself, but other materials like tungsten, silicon, molybdenum, silicon nitride, silicon carbide, quartz glass, cemented carbide, etc. Can also be used. The most important feature that the substrate material must have is that it should be able to withstand high temperatures and when it is attacked by the activated gas, it should not dissolve the deposited carbon.

Why are CVD Diamonds Brown?

The brown color of CVD diamonds can be attributed to carbon inclusions within the stone that may be non-diamond in nature. These inclusions may be formed during the process of treating the substrate with carbon gases.

Moreover, it is also believed that the brown coloration can also be a result of internal defects such as dislocations within the stone. However, unlike natural diamonds, the brown discoloration in CVD diamonds is not due to plastic deformation, as is the case when it comes to natural diamonds.

According to the CVD diamond review by GIA, it is possible that the brown hue in CVD diamonds is seen in the case of mass-produced CVD diamonds which are manipulated by adding nitrogen or oxygen to the gas mixture. However, this defect is easily correctable by using high pressure and high-temperature treatment after the formation of the diamond.

How to Identify CVD Diamonds?

Here are seven ways to identify CVD diamonds:

Using microscopes – If you place the diamond under the microscope, you will see that CVD diamonds have characteristic strain patterns which are different from the patterns seen in natural or mined diamonds.
Using a Diamond view machine – This machine uses high-energy UV radiation to identify synthetic diamonds from natural diamonds. When placed under this machine, CVD synthetic diamonds show a strong red fluorescence, which is not visible in naturally formed diamonds.
Inclusion pattern – Inclusions, especially when seen under a microscope, are present even in natural diamonds. However, the difference is that in CVD diamonds, these inclusions are less dispersed compared to natural diamonds.
Spectroscopy – This process refers to placing the diamonds under a spectroscope instrument. These instruments usually emit light at 737 nm. When exposed to this light, CVD diamonds show strong photoluminescence emission due to the presence of silicon in them, whereas this is not seen in natural diamonds.
Diamond tester – This instrument is used to check if the stone in your hand is a diamond or not, but it cannot maybe reveal whether it is a natural diamond or a man-made one. The dual electronic diamond tester uses thermal and electrical conductivity to check whether a stone is a diamond or not.
Fluorescence – Use an ultraviolet lamp that has both longwave and shortwave emissions. If the diamond shows a fluorescence of blue, it is confirmed that it is not a CVD diamond. Mined diamonds can show fluorescence in many colors, but the most common is blue.

Also, it should be noted that natural colorless diamonds show fluorescence typically under long-wave ultraviolet light, whereas the fluorescence becomes weaker when seen under short-wave ultraviolet light. On the other hand, synthetic diamonds are reversed, they show the strongest reaction under shortwave light.

Moreover, CVD diamonds show dark brown, almost red fluorescence under long-wave UV, which becomes moderately strong and turns yellowish-green in color under shortwave light. This is a positive confirmation of the presence of a synthetic diamond.

Do CVD Diamonds test the same as Real Diamonds?

Really diamonds have the same crystal structure as natural diamonds, and the chemical composition of both types of diamonds is the same. When we use the term synthetic diamonds or manufactured diamonds, these terms do not actually refer to the diamonds themselves, but rather the process of manufacturing them. Chemically speaking, the lab diamonds are indistinguishable from real diamonds.

However, there are some chemical properties that may be a little different. For instance, the testing methods mentioned above, like the inclusion pattern, fluorescence, and spectroscopy may show some difference between the two types of diamonds. However, this does not mean that the stones behave differently entreated two chemical, thermal, electrical, or any other kind of treatment.

What to Look for When Buying CVD Diamonds?

When you’re buying, or for that matter any type of lab ground diamond, it is necessary that you take some precautions to get the best value for your money. There are two things you need to remember before buying a CVD diamond.

The first is to avoid diamonds that have a brown color hue. There are many concede attacks that can cause the appearance of brown color in CVD diamonds. This affects the optical properties of the diamond. Look at the two pictures shown below.

The brown hue of the elaborated diamond is usually apparent when you see the diamond in the profile view. When you compare the two diamonds above, you will be able to see the difference quite clearly. The 2.03 H VS1 CVD diamond looks brown, while the 1.24 H VVS1 diamond appears yellow, just like a natural diamond.

It is recommended to avoid buying diamonds that have this hue or to go up in color to D, E, or F to minimize the appearance of the brown hue.

The second thing you need to consider is strain-induced birefringence, which gives the lab-created diamond a fuzzy appearance. This happens when there is a mismatch between the crystal lattices when the diamonds are grown layer by layer.

The result is that the diamond looks fuzzy and has strain lines.

It is recommended to avoid this type of diamond entirely. It should also be noted that train lines are not evaluated when grading the diamond for clarity, which is why sometimes they can still receive a vs1 grading even if the diamond is fuzzy.

What is the Cost of CVD Diamonds?

It is impossible to make a sweeping statement about whether or not CVD diamonds are costly or not, but it is true that they generally cost less than natural diamonds, usually, 20 to 30% less.

The amount of money you will pay for a 1.5-carat natural diamond can easily fetch you a 2 carat CVD diamond. This is because of several reasons. Mined diamonds required more physical labor, a long supply chain, and manipulation of pricing to ensure regular supply and demand. However, for CVD diamonds, this is not true. This is not to say that CVD diamonds are somehow cheap or less valuable, it is just that they are less expensive compared to their mined counterparts.

You can get CVD diamonds at the best price on loosegrowndiamond.com where their prices start from $300-$500.

What is the Temperature at Which CVD Diamonds Grow?

The temperatures at which optimum growth is obtained are between 700 to 900 degrees Celsius. It is also possible to grow diamonds at lower temperatures, but in this case, the growth rate will be extremely slow.

Are all Lab Grown Diamonds CVD Diamonds?

No, all lab-grown diamonds are not CVD diamonds. CVD is a relatively recent process and before it was introduced, lab grown diamonds were created using the HPHT approach. However, in the modern world, CVD is a more effective method for growing diamonds in the lab.

Where to Buy CVD Diamonds?

You can buy CVD diamonds at loose grown diamond worldwide shipping and a guarantee for all of their products. Moreover, we are a CVD diamond manufacturer and sell diamonds at wholesale prices so you are guaranteed to save a lot of money as well.

Whether you should choose a natural diamond or a CVD diamond is a question you should ask yourself before buying any kind of diamond jewelry. After all, of course, way less and does not have any of the complications that natural diamonds do.

Everything You Need To Know About Lab Created Yellow Diamonds

Posted on January 29, 2022March 19, 2024 by Martin Mora

Diamonds have become a statement of style, love, and perfection over the years. The different colored diamonds give us a unique and fashionable look for all the special occasions of our life. The yellow-colored fancy diamonds which are also called the canary yellow diamonds are very trendy, astonishing, and unique, which add a classy touch to your overall look.

Yellow Diamonds provide a luster that your regular colorless diamonds cannot seem to compete with. And people have started leaning towards it for the greater good. While buying colorless diamonds can be a tricky purchase, buying yellow diamonds is much trickier.

Yellow Diamonds have grown in demand for the last decade and all for the right reason. In this article, we will help you through everything and make it easy by providing a guide.

What are Lab Created Yellow Diamonds?

Almost all lab-produced diamonds have the same procedure through which they are formed, crystallization. This results in substances that are similar and almost identical to natural diamonds which take thousands of years to form. The time taken to produce the diamond affects the value of the diamond making it 40% less cheap.

The yellow diamond on the other hand is treated using nitrogen to get its color. The concentration will produce a variety of colors ranging from vivid yellow to dark yellow and even slightly brownish color. The nitrogen actually aids in the diamond’s rapid growth and thus increases the speed due to which it takes approximately a week to go from a rough diamond to a lab-grown yellow diamond.

How are the Lab Grown Yellow Diamonds Made?

The dazzling yellow colored lab-made diamonds get their spectacular color from the presence of certain elements, which are intentionally added to give them this look and color. Nitrogen is responsible for giving a yellowish touch to these diamonds. The more the quantity of nitrogen present in the diamond, the more extreme the yellow color of the diamond.

So now it is quite obvious that the yellow man-made diamond rings are created in the labs by adding nitrogen to the carbon elements during their formation process. The quantity of nitrogen is responsible for the colors ranging from light yellow to intense yellow to vivid yellow.

Properties of Yellow Lab-Made Diamonds

Hardness

Synthetic diamonds are even harder than natural diamonds. Their hardness depends on their levels of purity, orientation, and crystallization. So this means that the lab-made yellow diamonds are even harder than the naturally found rare yellow diamonds.

Inclusions

Certain levels of blemishes and inclusions are present in all the diamonds. But in the case of lab made diamonds, they are very. The same is the case with the yellow diamonds which we are talking about.

Quality

The yellow lab-made diamonds are very much unique in their look and color-wise, which makes them stand out from their counterparts in quite a few aspects. These days with the change in trends, many modern couples are opting for not-so-traditional diamonds and the designs for the same.

The most in-demand and the common ones are the light yellow diamonds and thus their cost is also quite less when compared to the others. But they are the natural ones. In the case of yellow lab diamonds, it is a bit difficult to find light yellow ones as the fancy vivid yellow diamond is more in demand and popular. Also called canary yellow diamonds. They are quite a rare combination and the most trendy and in demand these days.

They are a bit rare to find naturally but they can be quite easily made in the labs thus making them even more desirable as their price also decreases in this case.

How Fancy Color Lab Grown Diamonds Graded?

The process of certification of lab-made diamonds is similar to that of natural diamonds. Their grading is done after sending them to the experts in their field in the gem labs. The grading is done based on the popular 4C’s cut, clarity, color, and carat.

All the labs use the same methods and processes to grade the diamonds. They are graded individually by the experts and then the compilation of the individual results is done for the best possible optimum results. The grades are given to the diamonds unbiasedly in the case of this process.

In the case of the yellow lab-made diamonds, they are a bit different in terms of grading than the other lab-made ones. As in the case of the regular diamonds they are graded from D to Z, depending on the blemishes and the tint they have. But the yellow diamonds are the ones that pass only near about Z in the scale. Thus the color scale for fancy yellow diamonds gives a grade on the intensity of its color.

The scale ranges as:

Faint
Very Light
Light
Fancy Light
Fancy
Fancy Intense
Fancy Vivid, Fancy Deep, or Fancy Dark

The rest of the gradation is the same as that of the other lab-made diamonds, which are mentioned above along with the 4 C’s.

The GIA also grades lab-made diamonds but their grades are not as apt as in the case of natural diamonds.

So the IGI is the best for lab-created diamonds, which makes sure that the diamond you are buying is of the highest quality possible.

Positives of The Lab Grown Yellow Diamonds

Cost

As they are not mined and extracted deep down from the earth’s surface but are instead made with Artificial man-made technologies in the labs thus the cost of these diamonds is less as compared to the naturally found diamonds.

But this does not apply to the fact that the diamonds which are grown in labs are cheap. The supply chain in the case of the natural diamonds as large as they are mined first then distributed, cut, polished, and then sold to the jewelry manufacturers. But in the case of lab-grown diamonds the supply chain is shorter as the process of extraction and mining are skipped thus making its cost a bit less as compared to natural diamonds.

This is where the biggest saving comes in for buying lab created yellow diamonds. As in when you can create a diamond with a deep, canary yellow color on demand the price is naturally going to be lower than the ones extracted naturally. In general, the small-size diamonds or the ones fancy in color along with lighter hue are much more common and cheaper, therefore.

Ethical

Many years ago there was a taboo associated with the mining industry, as many believed that various unethical practices were being carried out in their extraction process. They were even referred to as the blood diamonds as many believed that they are used to fund violence and the miners and their families were overexploited and taken for granted. Also, they promoted child labor in various places.

However, due to the establishment of the Kimberley process, these particles have come to a halt to a level. So lab-grown diamonds are your ideal choice if you are a peace-friendly person and also need reassurance as to how your diamonds were made.

Environment Friendly

As we all are aware of the fact that during the process of mining, there are various bad and negative impacts on the environment and the surroundings. Although various steps have been taken to reduce and avoid them to a level, they still exist.

But in the case of lab-grown diamonds, you will not face such an issue as they are quite environment-friendly and take less energy for their creation. They also are pocket-friendly and can save a few bucks which can be used elsewhere.

How to Choose the Best Yellow Lab Made Diamonds

You can take the help of professionals and gemologists in this case as they are in this field for years and years. In terms of purchasing the diamonds, you can opt for either offline or online mode. Many customers tend to visit the shops in person and buy them as they believe in taking a visual look at the diamonds. Whereas in the case of online purchases, you will get good discounts and offers.

The variety remains the same in both cases mostly as diamonds are very much in demand throughout the years. So the choice is solely yours, choose wisely and accordingly. But Whatever the mode of purchase, the grade and scale of the diamond should never be ignored.

The yellow lab made diamonds are the more modern, ethnic, and fancy choice and also are trending these days. Many brides tend to opt for them these days rather than the traditional colorless diamonds.

The setting of the ring should never be ignored as it directly impacts the look and charm of the ring. As in the reflection of the light and other factors to depend on them. The more the diamond reflects the light the more it shines and the more appealing and enticing it looks to the inhuman eye.

As lab created yellow diamonds are commonly a darker shade already, you do not need to rely on the setting to produce more vivid colors. But should take note of how the setting will contrast and blend in with the color of the diamond. As in they both should complement each other and enhance each other’s look and beauty. You can also pair a vivid, canary yellow lab diamond along with a white gold ring or clear diamond accents. If in case you want to opt for a more complementary look, you can pair the fancy yellow diamond along with a bar of rose gold or a yellow gold ring, which as a result will give it a warmer and classic look.

How Lab Created Diamonds are Made?

Posted on January 29, 2022April 25, 2025 by Martin Mora

Natural diamonds are made by precise and perfectly bonded carbon crystal lattices. Due to this, they gain immense strength. According to scientists natural diamonds are created under extreme pressure and high temperature, they take about 1 billion to 3 billion years to form depending on the conditions.

Man made diamonds, on the other hand, are created within six to eight weeks. These lab grown diamonds are created in a controlled environment, with the help of advanced technology. It is like a chamber in which the material is put which will later be converted into a loose diamond. The chamber replicates the conditions of the earth’s crust, which are needed to create a man made diamond.

But have you ever stopped to wonder how these dazzling gems are made? In this comprehensive guide, we’ll take a deep dive into the intricate process behind lab grown diamond creation, uncovering the science and technology that makes it all possible.

After a man made diamond is created it is cut into different shapes, polished, and graded just like a normal natural diamond. A man made diamond has the same physical, chemical, and optical properties as that of a natural loose diamond. Due to this, it becomes nearly impossible to tell the difference between a lab grown diamond and a natural loose diamond, with the naked eye.

To tell the two apart special types of equipment and a professional is needed to inspect them. Man made diamonds are a revolutionary discovery that reshaped the whole diamond market. These loose diamonds have many benefits and somewhat more benefits than natural diamonds.

There are Mainly Two Main Methods that Opted to Create Man Made Diamonds:

1. CVD Diamond Method
2. HPHT Synthetic Diamond Method

Now let us briefly explain both of these methods, and how they are used to create loose, white, and fancy diamonds.

CVD Diamond Method

CVD stands for Chemical Vapour Decomposition, it is used to create high-quality loose diamonds. In this method, a material is put inside a chamber in the presence of a pure rich carbon plasma. As soon as the process starts, carbon atoms get deposited on the material, and with time it forms a man made diamond.

To get colored fancy diamonds, specific trace elements are inserted into the carbon crystal lattice during the growing phase. Depending on the amount of trace element and type of trace element inserted, does the fancy diamond get its color.

CVD Diamond method also has some types, which are:
• Plasma Enhanced Chemical Vapour Decomposition (PECVD)
• Microwave Plasma Chemical Vapour Decomposition (MPCVD)
• Low-pressure Chemical Vapour Decomposition (LPCVD)
• Ultra-High Vacuum Chemical Vapour Decomposition (UHVCVD)

HPHT Synthetic Diamond Method

HPHT stands for High-Pressure-High-Temperature, which is also the procedure used to create man made diamonds. An HPHT Synthetic Diamond making machine is able to generate 60,000 ATM (atmospheric pressure) and 2500°C temperature. Thus forming an environment similar to that under the earth’s crust, which assists the formation of a man made diamond.

The elements and materials used to create lab-grown loose diamonds are:

A tiny diamond seed
Highly refined graphite
A high-quality catalyst mixture containing metals and powders

When the machine is turned on, due to high pressure and high temperature, the catalyst mixture turns into a molten form. Which then causes the refined graphite to dissolve in it, and form various layers over the diamond seed. Then after the cooling is done, an HPHT synthetic diamond has been formed.

To carry out the HPHT Synthetic Diamond making method, and apply the required conditions, two types of machines or press designs are used.

Cubic Press- Creates high temperature and pressure with the help of pistons, which are located throughout the machine and provide pressure from different directions.

Belt Press- In this machine high pressure is formed by two strength pistons. These pistons apply equal pressure in opposite directions.

Should You Buy Lab Created Diamonds?

Whether or not you should buy lab grown diamonds depends on various factors, including your personal preferences, ethical considerations, and budget. Here are some points to consider:

To start, let’s explore the benefits of diamonds produced in laboratories.

Lab grown diamonds are created in controlled environments, eliminating the need for environmentally destructive mining practices and reducing the risk of exploitation associated with traditional diamond mining.

Lab created diamonds often come at a lower price point than natural diamonds, making them accessible to a broader range of consumers.

Like mined diamonds, lab grown diamonds can be certified by reputable gemological laboratories.

Lab grown diamonds are virtually identical to mined diamonds in terms of appearance and chemical composition. They exhibit the same brilliance, sparkle, and durability as natural diamonds. If you’re concerned about quality, rest assured that lab grown diamonds can be just as beautiful and durable.

Ultimately, your choice to purchase lab grown diamonds hinges on your priorities and principles. If you prioritize ethical and environmental considerations while seeking a more budget-friendly option, purchasing certified lab created diamonds from LGD at the best available price might be appealing.
