Most people who want to add some sparkle to their lives choose diamonds. In recent years, however, CVD (chemical vapor deposition) has become very popular because it provides diamond jewelry at significantly lower prices than regular mined stones. What is CVD, and why do people prefer it over other types of diamonds?

Chemical Vapor Deposition (CVD)

CVD diamond manufacturer in Mumbai produces high-quality diamonds at low costs. Many jewelers prefer CVD to other forms of manufacturing because they get consistent results and can easily control the quality of the final product.

Several types of diamonds are created using chemical vapor deposition (CVD). Single crystal growth and polycrystalline growth are the two main methods of creating CVD diamonds. Both processes rely on depositing carbon atoms into the diamond lattice structure. 

The difference between them lies in the size of the crystals formed. Single crystal growth produces larger diamonds than polycrystalline growth. However, the latter tends to produce better quality stones. 

Additionally, because the CVD process occurs under extreme heat and pressure, the temperature required to create CVD diamonds can reach over 2000 degrees Celsius. Because of the extreme conditions involved, CVD diamonds tend to be much harder than other forms of mined diamonds.

What makes CVD diamonds so popular?

CVD diamonds (colorless/vivid diamonds) are becoming very popular due to their unique characteristics. The reasons for this are varied but include improved gemological characteristics such as brilliance, fire, scintillation, and light efficiency. 

They also tend to be less affected by natural blemishes or other imperfections. In addition to these traits, they also offer various uses.

Diamonds aren’t always expensive. However, when purchasing diamond jewelry, you should look at the quality of the diamond rather than its price tag. The term ‘certified’ means that the diamond has passed rigorous tests and certification procedures before being released onto the market. CVD (chemical vapor deposition) is one method to create diamonds from scratch. This process creates amazing gemstones often far superior to those found naturally.

CVD diamonds manufacturer in India is known worldwide for the finest and purest type of diamond. They are highly sought after because they offer both brilliance and fire.

Why CVD diamond is your most popular friend?

A large percentage of the world’s rough diamonds are mined and sold using the CVD method. This technique involves removing impurities from the surface of the diamonds through chemical treatments. CVD diamond manufacturers in Surat tend to have higher quality levels than conventional diamonds.

They are popular because they are small, affordable, lightweight, and easy to wear. They don’t take up much space in your jewelry box or pocket. You can always keep them with you without being worried about losing them. You will never go wrong if you own one.

Other reasons for their popularity is due to their durability and attractiveness. Moreover, they are easy to clean and maintain. They are also quite hard and resistant to heat and corrosion, so they are used for cutting tools, jewelry, etc.

Also they are a symbol of wealth, stability, and longevity. They also look good in any jewelry setting.

CVD diamond companies in India are becoming increasingly popular because their products are hypoallergenic compared to other diamond types. 

Benefits of CVD diamonds over natural diamonds

CVD (chemical vapor deposition) is a manufacturing process where a thin layer of material is deposited on a substrate using chemical reactions. This process allows manufacturers to create complex shapes or structures, such as those in computer chips and solar panels.

CVD diamonds offer several benefits over mined gemstones, such as their hardness and durability. They also come at a lower cost due to their high production volumes. There are three main advantages to choosing CVD diamonds over mined stones: low cost, hypo-allergenicity, and enhanced optical properties.

Several CVD diamond manufacturers in Mumbai offer CVD diamond production services. They differ mainly in terms of the size of the finished gemstone. For example, some produce stones weighing less than 1 carat, while other manufacturers offer larger stones ranging between 2 and 50 carats.

Why is CVD diamond gaining popularity as a jewelry and investment option?

There are several reasons why CVD diamond jewelry has become so popular over the years. Some of them are listed below:

✔ CVD diamonds are becoming very popular because they provide better value than regular diamonds. What are some other reasons why these gems are so attractive?

✔ CVD (chemical vapor deposition) diamonds are created through a special manufacturing method. These diamonds are also high-pressure high temperature (HPHT) or ultra-high-pressure high temperature (UHPT). They are the hardest gemstones and are often called “white gold” due to their luxurious appearance. Because of their unique properties, they are considered the most valuable diamond variety today.

✔ Many consumers prefer CVD diamond manufacturers in Hongkong because they offer excellent performance across multiple facets – from cut to fire. This makes them ideal for jewelry applications, where light refraction and scattering affect the visual appeal.

✔ Because of their low markup, CVD diamonds cost less than other types of diamonds. In addition, you can purchase them at a much higher volume. As a result, CVD diamonds are gaining popularity among investors looking to diversify their portfolios.

✔ You might choose to invest in these precious stones because they offer a safe means of saving and investing. The long-term returns from a diamond investment are also high.

Introduction

Synthetic diamonds are considered to be one of the most useful results of technological advancements that have happened in the past few decades. Unlike other inventions, lab grown diamonds manufacturer do not have disadvantages that make them less preferable than mined diamonds. In fact, these gemstones are becoming popular by the day.

In terms of physical properties and looks, synthetic diamonds are not different from natural rough stones. Yet, there are considerable differences between the two. Knowing these differences can help to analyze a diamond better.

Mode of origin

Natural diamonds are the result of environmental changes and circumstances that decide the nature and texture of the rough stone formed. Immense heat and pressure that arise as the consequence of different natural phenomena lead to the formation of these incredible stones that vary in size, texture, and color.

Diamonds are found deep under the Earth’s crust. The depth can go up to 150-200 km below the surface. Due to the high pressure here, the carbon particles present in the soil get crystallized forming the stones that we call as diamonds. Going below the surface to reach these diamonds is nearly impossible. Nature does play a part in bringing these stones near to the surface as well. The formation of molten magma under the crust, at temperatures of 900 to 1,300 degrees Celsius along with 45 to 60 kilobytes pressure becomes a path for the diamonds to reach the upper layers. When the magma erupts and expands, the rocks bearing the diamonds also move upward with it, making it easy for the humans to reach them.

These diamond bearing rocks are then dug out through mining, which involves physical labor and machines. The process is difficult and carries risk elements for those who become a part of it. Extraction of diamonds is done in different ways, such as pipe mining, alluvial mining and marine mining.

Lab grown diamonds manufacturer and wholesaler, on the other hand, are completely formed in a side a laboratory. From the beginning till the very end, synthetic diamonds are the products of a manually created atmosphere where diamond seeds taken from natural diamonds are developed in diamond-making machines. The lab grown diamonds are primarily of two types: HPHT diamonds and CVD diamonds.

The HPHT or High Pressure, High Temperature method is where high pressure and high temperature is applied to graphite. The intense atmosphere makes the graphite dissolve into carbon atoms and these particles with the help of a liquid nickel or cobalt get coated around the diamond seed. The whole process happens inside a small capsule. CVD diamonds are the result of the method called Chemical Vapor Deposition. Here, the diamond seed is placed inside a chamber filled with hydrocarbon gas. At low temperature and high pressure, the carbon particles from the gas start to attach themselves to the seed, with time making it grow in size. The CVD method is more cost-friendly compared to the HPHT method.

Time taken for the formation

Natural diamonds are the result of years of changes that happen in nature. A diamond takes approximately 1 to 3 billion years to form. This is due to the requirement of the right conditions and the slow mode in which these conditions develop.

Lab grown diamonds  take a period of 3 to 4 months for the formation. As the atmosphere is artificially created, the process of formation is smoother and faster compared to natural diamonds. Unlike natural diamonds, the path of formation is not affected by any other phenomenon. Once placed inside the machine, the diamond seed stays at the same place it reaches its matured state. Once the diamond reaches its final form it is taken out, analyzed, and polished.

Environmental Impact

Rarity and difficulty to extract make natural diamonds valuable. Yet, the same reasons are also why these gemstones are losing their place to synthetic diamonds. The procedures that are involved in extracting natural diamonds are harmful not just to the Earth, but also to other living beings including humans. Mining leaves huge holes that affect the ecosystem. This leads to further problems such as soil erosion, deforestation, landslides, earthquakes, etc.

Indigenous communities across the world are often under threat as mining takes up land. They are helpless even when their livelihoods are affected severely due to these activities. Often they lose their homes in the process. Moreover, manual labour involved is at risk of serious injuries or even death. Workers are exploited and are made to work without adequate safety measures. Child labour, another major problem is now strictly banned in many countries.

With synthetic diamonds, none of the above mentioned concerns arise. They are made completely in safe environments closed inside the four walls. Machines are involved in the making of these diamonds that the demand for manual labour is almost null.

Chemical Properties

In terms of chemical deposition, both natural and synthetic diamonds are the same. As the core element is carbon, the diamonds formed by developing it tend to have the same chemical and optical properties whether formed naturally or otherwise. Due to this reason, telling them apart from each other is not easy. Diamond experts use methods and machines for identification.

Presence of Inclusions

Metal fluxes are used by synthetic diamonds for formation. These fluxes leave marks on the surface of the diamonds grown artificially. Synthetic diamonds, therefore, have metallic inclusions on their texture. They play a significant part in deciding the quality of the diamond. Varying in size, some inclusions are microscopic while others can be observed with naked eyes. Moreover, these tend to be magnetic in nature and get attracted to strong magnets if placed nearby.

Natural diamonds do not have inclusions in them. Due to the natural way in which they are formed, magnetic inclusions are not a part of them. Genealogists use inclusions as a way of identifying synthetic diamonds.

Spectral features

The two types of diamond also differ in the way they project their spectral features. Whether colored or natural, the way a gem reflects light can also reveal the kind of diamond it is. The most common spectral features, observed are lines that are measured in nanometer (nm)

Natural diamonds tend to have “Cape lines”. It is observed that these lines at 415nm in a colorless or light yellow diamond means that the diamond is natural born. Apart from the said measurement, there are other specific quantities of lines set to identify natural diamonds.

Lab grown diamonds tend to project spectral features in a different way. The diamonds that are born with yellow to brownish hue and project lines at 470 and 700nm are identified as synthetic ones.

Price

Diamonds that are formed as a result of different natural phenomena are rare and require a huge effort for extraction. The cost involved in the process is higher than the cost of production of laboratory diamonds. This gets reflected in the market price of these diamonds as well.

CVD diamonds and HPHT diamonds cost approximately 30% lower than natural diamonds. The quality being similar, the lesser price for one type of diamonds make them much popular in the market. However, lab-grown diamonds in recent years have registered a hike in price due to the increase in demand,

Color

In terms of color, synthetic diamonds take the edge over natural diamonds. The color of a diamond shows how many impurities are trapped inside its composition. As such impurities can be added without difficulty in synthetic diamonds, the color variations are more in them.

Diamonds are also graded based on the colors. ‘D’ denotes the purest ones and hence is completely colorless. It is observed that natural diamonds are mostly seen with a slight hue of yellow or its darkest shade and colorless ones are extremely rare to be found. Colored natural diamonds are the costliest among the types. These gorgeous stones are often found to be blue or pink in color.

Lab-grown diamonds are available in almost all colors as developing them in the needed hue can happen with ease along with the process of formation. Hence, these gem-quality stones come in almost all color grades. However, they are often found in yellow to brownish yellow shades. Blue and colorless synthetic diamonds are also developed, but not frequently.

Why should you give preference for lab created diamonds over natural diamonds?

Lab created diamonds are the future. They are affordable and give all the benefits of natural diamonds without compromise in quality or clarity. CVD diamonds and HPHT diamonds are produced by many prominent diamond manufacturers in the country. In fact, the Indian lab created diamonds are in high demand across the world and are considered to take over the global diamond market in the coming decades. Our country is fortunate to have many pioneers in the field as top-quality lab grown diamonds can be acquired at low prices.

Most importantly, it is the moral side that these diamonds hold that makes them special. As the climatic impact of human innovations is making nature change for the worse, governments, international organizations, and global environmental groups are trying to find ways to correct the mistakes committed. Lab-grown diamonds are one such way in which you as a global citizen can make a significant contribution in this quest to go back to the good old times.

Diamond is one of the most precious gems on the planet. And nowadays these diamonds have switched to lab grown diamonds that don’t affect nature. There are lab grown diamond manufacturer and wholesaler dealing with a variety of lab-grown diamonds that are precious and sparkling. The diamonds are manufactured in different shapes and colours that give you a lot of desired options.

The Past of Lab-Grown Diamonds

The myth is that diamonds are only available to the wealthy and royal families, but this is not true.The diamond industry is flourishing, and it’s impressive to see a wide range of diamonds and gemstones available. Today’s millennial generation is aware of their options and is familiar with the various diamonds on the market. However, in order to provide them with something affordable, CVD diamonds were invented.

The CVD diamond manufacturer in India uses modern technology and techniques to make a beautiful lab-grown diamond. As you know, the mining of diamonds is a very tough process that leads to soil erosion and other harmful effects on nature. These man-made diamonds are not harmful to nature and are a bit less expensive as compared to natural diamonds.

Production of lab-grown diamonds

The lab grown diamond manufacturer in India and throughout the globe produces these diamonds through technological processes. With the use of different methods, these diamonds are made. The original method used high temperatures and high pressure to create the diamond. Another process is chemical vapour deposition, which is popularly known as CVD.

In this method, the diamond is grown from a hydrocarbon gas mixture. To create a CVD diamond, the substrate is prepared; various amounts of gases are combined in the chamber and then energised to create a sparkling diamond.The CVD diamond manufacturer Surat, usually uses these techniques to produce the shining substance.

Lab Grown Diamond vs Natural Diamonds

Since the early 1940s, lab-grown diamonds, also referred to as man-made or synthetic diamonds, have seen progress. In the beginning, it was used only as an industrial diamond for various industrial purposes. The turning point came when GE created its own lab-grown diamond in December 1954 and later made an official announcement of the lab-made diamond in February 1955.

During wartime, a handful of diamond mining companies were not able to fulfil the need for a reliable, cost-effective, and consistent supply of diamonds. It was in the late 1980s when gem-quality lab-grown diamonds were made commercially available. Later on, the demand for lab-grown diamonds increased and people started buying them.

Today, you can get your favourite diamonds from different websites like rahiimpex.in, which offers you a wide range of CVD diamonds. The process of growing these diamonds has made them popular all around the globe, due to which you can now see lab grown diamond manufacturers in the USA and CVD diamond manufacturers in Hong Kong providing you the best diamonds in the world.

With the increase of lab-grown diamond manufacturers in India, people have become more aware of their choices and they now love to buy lab grown diamonds online from particular websites.

A lab grown diamond is like a test tube baby. Born pure and free of any contamination, these gem quality stones are excellent for adorning your jewelry. From necklaces to engagement rings, these stones are now used everywhere as a substitute for mined diamonds. Beautiful as they are, these stones can get filthy easily. But there are often ways to keep them bright and shiny if you are ready to follow certain tips that we are going to tell you through this blog. So, let’s see what they are:

Be careful, they can chip!

Lab grown diamonds or natural diamonds are the hardest objects found on the earth. But that does not mean they cannot chip off. If a cutter can slice off a part of a diamond then you can also do the same if you accidentally hit the lab grown diamond somewhere hard. So be very careful while you handle these diamonds. Give extra care, especially around the girdle, the edges and the culet for these areas are thin in width and as a result, are very weak and vulnerable. Lab grown diamond manufacturer and lab grown diamond suppliers take precautions while exporting the diamonds to faraway places. To prevent any sort of damage they are kept in good secure boxes that will ensure that the diamonds stay intact. Keep them away from dust! Like your skin, lab grown diamonds can also be affected by atmospheric impurities. Protect your lab grown diamonds from dust and smoke for these can tarnish the shine temporarily. As Mentioned in the previous section, a coating of dirt will diminish the luster. And this is why you see that the diamonds are always kept inside glass boxes or bags by the lab grown diamond manufacturers.

Avoid touching them!

Yes, they are alluring, but do not fall for that and touch these stones. Lab grown diamonds can repel water, but they can easily catch grease. And this can diminish their glow. When you touch the polished surface of a diamond the oil or grease from your fingers can get transferred to its surface thereby creating a coat of filth. If you are not careful, then this coating can get thicker as you keep touching the stones without giving a care. Imagine the effect that this can have on the luster. Store them like nothing else. We compared these stones to test-tube babies. Well, they are to be stored like how you take care of a baby too. If you go to buy lab grown diamonds in India, you will get to see how the lab grown diamond manufacturers exhibit these synthetic diamonds. They are kept in utmost safety and security. Mostly you will find them wrapped in fabric-lined bags or clothes. Covered in soft clothes, diamonds are safe from external hard surfaces or other objects, thereby preventing any chances of getting scratches or other similar blemishes. Moreover, it is often advised to keep diamonds in separate bags. Each diamond should be kept in its bag or compartment in a box away from other diamonds or gems.

Clean them with a soft touch.

Yes, these stones need to be handled with care while cleaning. Use hard bristle brushes to dust off the dirt can result in scratches or marks on the diamond surface. Cleaning these shiny gems is not a difficult task. Mild soap will do the trick. Mix this liquid in water and use the solution to wash off the filth with a soft brush and clean water. Ensure that you do not press hard against the gem while doing so. Do not use chemical solutions with chlorine or abrasives especially if your synthetic diamond is decked in a jewelry piece. Such chemicals might erode the metal rendering the diamond loose. Also, make sure to do this frequently to keep the diamond squeaky clean, and bright all the time. Regular cleaning will also make maintenance easier. When you are not wearing or using the diamond, make sure to keep them in places that are free of impurities.

In case you feel that your lab grown diamond needs a thorough cleaning, you can always approach a jeweler or lab grown diamond manufacturer, or lab grown diamond supplier to get it cleaned. They use ultrasonic cleaning machines are excellent in cleaning the dirt off within a few minutes.

Conclusion

Lab grown diamond manufacturers make these incredible synthetic stones in highly sophisticated machines. They, therefore, originate in the cleanest of environments humans can create. Hence, they need to be given the care they need to maintain their shine. Use the tips that we shared in this blog and see how you can lab grown diamonds to stay a timeless beauty.

Lab grown diamonds are without a doubt taking over the diamond markets across the planet. As technology is becoming sophisticated by the day, the production of man-made diamonds has taken new leaps. Today, they are available throughout the world, in different sizes, shapes, and colors. But, have you given a thought about how valuable these pretty stones are? Do you know what determines their prices or how much value they hold if you look to resell them?

Let’s take a look in all these, shall we?

Can lab grown diamonds be equated with natural diamonds in terms of value?

No, lab created diamonds cannot be equated with natural diamonds in terms of value. Of course, you cannot put the same value for something that is made in an artificial environment against its alternative that is dug with great effort from underneath the earth’s crust using machines that are big machines and human labor.  And this is exactly why lab grown diamonds are priced 20-30% lesser than natural diamonds.

These pocket-friendly gem-quality stones are therefore preferred more than natural diamonds as they give you the same essence that natural diamonds provide at a lesser price.

In fact, these artificial diamonds are seen to have gone way down with their prices in the past few years. De Beers, the 130 year old diamond company that is the pioneer in the diamond business in the whole world in 2018 has reduced the price of lab grown diamonds to create a considerable price division between natural and man-made diamonds.

‘So why did De Beers do this?’ one may ask. Well, the company felt the need for natural diamonds to be taken more valuable by the consumers for artificial diamonds were getting more popular by the day.

When the consumers understood that they can get better quality for less prices, people began to prefer the stones over natural ones even for important occasions like engagements.

De Beers thought of reducing the price of man-made diamonds so much that the price was reduced from $2400 to $800 per carat. This, the company believed, will make the buyers give more significance to natural diamonds making them choose for auspicious events.

This is the impact that lab created diamonds have made in the last decade.

How is a lab created diamond priced?

A lab grown diamond is priced based on the 4Cs. Check out what they are…

Cut: The most important factor that determines the quality of a synthetic diamond is its cut. The cut gives the diamond its identity. It takes state-of-art technology to make the best cut lab grown diamonds. A cut should not be too deep or too shallow.  Either way, the light reflection would not be optimal. The most important diamond cuts are step, brilliant or mixed.

Clarity: The intensity with which a diamond reflects light is its clarity. The clarity determines the shine which shows how pure the stone is. Any blemish or inclusion can impact the flow of light, thereby reducing its beauty. A well-cut diamond has clarity at its best.

Color: The rare the color is, the more valuable the synthetic diamond would be. In natural diamonds, the color is a slight tint to the original white tone of the diamond. In artificial diamonds, the color can be added with the help of machines. Blue lab created diamond is one of the costliest among the lot as it is similar to the natural blue diamonds that are very rare.

Carat: Carat is the weight of a diamond. It plays only a minimal role in deciding the price of a synthetic diamond. When polished a rough stone (the raw stone taken right from the machine and not worked upon) may lose some of its parts and therefore the weight reduces. Usually, when the price is discussed, it is stated as price per carat. More than carat it is the other three elements that determine the quality of a diamond the most.

Based on perfect standards the diamonds are chiseled to bring out the best.

Being less priced, are lab grown diamonds lower in quality?

Obviously, one may tend to think this is true for why they would cost much less than natural diamonds just because they are made in labs. Well, that is a fact.

When compared to natural diamonds, lab created diamonds comes on the same level or maybe even higher.

This might be difficult for you to believe. Then do read the points below to know why it is so.

They are produced in a controlled environment:

Prior to the starting of the making procedure, the temperature and other conditions for formations are decided and pre-set by the manufacturers. When a diamond gets to take its form inside the sophisticated diamond manufacturing machines, the process happens without any flaws. Rather, it ensures that the diamonds are produced in the best conditions there can be.

They reach maturity without any disruptions:

Natural diamonds undergo different dire situations before they come into man’s hands. Hence, they are often flawed in texture with scratches or marks. The shine of a diamond is determined by how flawless the body is.

Lab created diamonds are made in a safe atmosphere. They are almost like a test tube baby kept in side a very sensitive yet strong environment. The diamonds thus never have to deal with anything that can impact their sharpness or clarity. Hence, they take birth and come out of the machines as perfect stones.

They are flawless and purer than natural diamonds:

Due to the above mentioned reasons, most lab grown diamonds are the synonym for perfection. They come in higher quality than natural diamonds as they are made with clear cut measurements in a perfected atmosphere.

Even when they are priced less, the satisfaction that these gem-quality stones provide is inexplicable. In terms of quality and strength, they are without doubt above natural diamonds.

What about the resale value of lab grown diamonds?

It is a known fact that natural diamonds do not have much resale value. The same goes with lab grown diamonds. You would not be able to resell them at the same price that you have bought them.

Therefore, unlike gold, lab grown diamonds would not fetch you a fortune if you look to sell them after years of usage. They are not therefore the perfect investment. However, they will give you back a handsome amount that you can be satisfied with for immediate monetary needs.

A few factors that you can ensure to get the maximum value for your diamonds are:

Ensure they have certification: Make sure to buy lab grown diamonds that are backed by proper certification. Diamonds with such a guarantee are often considered to be of high quality. Having an authentic, established proof that states the value of the stone can give more value to it. This can help you demand the maximum price at the time of reselling.

The Gemological Institute of America or GIA accepted that the lab grown diamonds are in fact real diamonds in 2007. GIA is only one of the institutes that give certifications for lab grown diamonds. Similarly, there are other established organizations that give certifications such as AGS, HRD, IIG etc.

Observe the market trends: Keep an eye for the changing trends in the diamond market. The prices for lab grown diamonds fluctuate with time. Make sure to sell your artificial diamond when the prices are considerably high. This way, you can ensure that you might be getting the maximum worth for your diamond present at the time.

Choose your diamond carefully: Try to go for lab grown diamonds that are rare in colour or slightly bigger than others. These are the types that retain their value the most. While you look to resell them these particular types can give you a jackpot.

How much does a lab grown diamond cost now?

The beginning price of a synthetic diamond can vary from $900 to $1000 per carat. The price just like for any element can differ from one day to the next. This change is based on the global market movements for these stones.

To conclude

Lab grown diamond manufacturer in India is a lot beneficial since they give you more than what a natural diamond can offer at better prices. Their production involves neither labor nor they do not harm nature in any way during the process. Having only positive elements, these incredible stones should be the most affordable luxury that anyone can have!
