The History of lab-grown diamonds

The History of Lab grown diamonds

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.


5 Simple Tricks to Keep Your Lab Grown Diamond Shining

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.


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.

How valuable is a lab created diamond?

How valuable is a lab created diamond?

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!

Lab Grown Diamonds – The Future of Diamond Industry: Myth or Fact?

In 2003, a significant development happened in the world of diamonds. The Kimberly process was universally accepted as the method to identify “conflict diamonds”. But, it did not prove to be 100% effective.

Mined diamonds despite being one of the most valuable things on Earth always carried a pinch of guilt with them. The toll of labor, sweat, and energy that goes behind their excavation has resulted in discussions in many international forums. 

With the advent of lab grown diamonds, however, the diamond industry began to see changes both on the supply and demand side. Today, reports say that a major chunk of the diamond purchasers in the world is moving away from natural mined diamonds as they are getting closer to lab grown diamonds.

Why do 70% of the millennials prefer lab grown diamonds today?

The demand for diamonds, especially engagement rings has come up mostly from the younger population. They need special occasions in their life to be validated by the presence of something rare and beautiful, something that stands the test of time.

And due to this reason, conventional diamonds could adorn most of the engagement rings at one time. But today, things have changed. The eco-consciousness of the young age group has proven that it is not just the uniqueness of the beauty of a stone that matters nowadays, but how sustainable they are.

How are lab grown diamonds sustainable?

Lab grown diamonds are born in machines crafted to build stones that are chemically, optically, and physically the same as natural diamonds. 

While natural diamonds take billions of years to form, unconventional diamonds are made by the lab grown diamond manufacturers within three to four weeks.  

There are two methods of production CVD Diamond and HPHT Diamond. Both these create synthetic diamonds that are equal to or even better than natural diamonds. This is because they are made in a safe environment unlike the bowels of the earth where lava and hard substances like rocks impact the quality of natural diamonds as they make their way up to the Earth’s surface.

To know about the two methods of synthetic diamond production, do read –

The vast difference in the energy consumption of mining and making a diamond above ground is another factor that makes the present a good time for lab grown diamond sellers and lab grown diamond wholesalers

Diamond Foundry, a San Francisco-based producer of man-made diamond conducted research on energy consumption that happens as a part of mining and making diamonds artificially. The results clearly show that mining takes almost an entire factor more energy than making. 

And this becomes a bit more critical when we talk about energy resource. Diesel is used for mining while the lab grown diamonds can be made with the aid of renewable resources. How does that sound?

In addition to this, the potential pollution of water bodies due to the sulfide presence of the rocks left after mining is an issue that has been discussed over and over but has found no solution till now.

Moreover, the land is harmed so much unlike any other activity. To get a naturally made stone, tonnes of soil need to be dug out. This affects the ecosystem severely. Deforestation leads to soil erosion and many other ecological problems.

The dangerous working conditions have led to accidents that have taken the lives of thousands of workers. It becomes even more saddening to know that in some places children are also made.

The downside of mining does not end here. And this is exactly why lab grown diamonds are considered to be the stars of the future. 

People are becoming more and more conscious about their responsibilities as global citizens. And the younger generation is looking for products that give them not outward satisfaction, but the contentment of using something eco-friendly and guilt-free. Slowly, this will take over all age groups given how the world is needed for good care from its inhabitants. Making them even more attractive is how budget-friendly they are. They cost 30% less than mined diamonds.

And this is why lab grown diamond wholesalers and lab grown diamonds suppliers are finding their business booming over the past few years. If you go to buy lab grown diamonds in India, you will find that the market is rich with lab grown diamond manufacturers and the competition is pretty high. The synthetic diamonds from India are getting world attention and the graph will only rise in the future.


The years to come are definitely showing a green signal for lab-grown diamonds. With time, these diamonds will take over the natural diamonds. Even the famous natural diamond sellers have acknowledged how the sale of mined diamonds has reduced since the lab grown diamonds have proven their worth.

Why Should I Choose CVD Diamonds Over Others?

Why Should I Choose CVD Diamonds Over Others?

CVD diamonds are not just synthetic diamonds. They are much more. The immense capability of CVD diamonds to light up your eyes and mind the moment you lay eyes on them is just one way of describing their specialty. 

CVD diamonds in India are very popular in the world in terms of their quality and purity.

This incredible invention of man has a lot under its umbrella. The benefits they have over natural and other artificial diamonds are numerous. And this blog is going to tell you what these advantages are.

They are the purest form of diamonds.

CVD or Chemical Vapor Deposition is a method in which a thin diamond seed is put inside a chamber which is later filled with a carbon-rich gas. At high temperatures, a microwave beam passes through the gas disintegrating its molecules. 

The molecules then coat the diamond seed, making the diamond seed grow in size. This process is called crystallization. In a few weeks, the formation will be completed. When it’s finished, the diamond is taken out in its raw form.

Lab grown diamond manufacturers have constantly experimented with the method of production of CVD diamonds. 

In the past few decades, they began to use Type 1 diamond seeds to improve the color of the diamond that is produced.

Type 2 is the purest form of diamond in the world. Hence, something that develops from the seed of the same will be pure as well. This makes CVD diamonds more special than HPHT lab grown diamonds.

In fact, there are lab grown diamond manufacturers who claim that their CVD diamonds come in the same league as Koh-I-Noor.

They are flawless than their counterparts.

The process is simple and does not carry the diamond seed through different difficult stages like natural diamonds. Once placed inside the chamber it stays there when crystallization happens. 

The diamond takes birth in a pretty safe environment without even moving an inch. Unlike natural diamonds that travel distances before reaching the human hands, CVD diamonds are made with ultra care.

And what does this imply?

They have a minimal set of strains, impurities, and inclusions; that they are one of the purest gems you can find. 

They are whiter and brighter than other diamonds.

As strains or marks on them are very few, the reflection of light will be unhindered. The path of light from the outside to inside and back will be perfect and the shine will make you feel overwhelmed.

They are whiter and brighter than natural diamonds and HPHT lab grown diamonds, making them the best choice for adorning an engagement ring!

They are produced with inexpensive equipment and therefore cost less.

This is an advantage for the lab grown diamond manufacturers. You can imagine how sophisticated a machine should be to recreate something in a few weeks that is naturally formed taking decades. 

The equipment and the procedure might therefore incur a pretty high cost for the manufacture. But when compared to HPHT lab grown diamonds, CVD diamond manufacturing requires a less intensive environment.

The temperature and pressure for CVD diamond production are comparatively less. The machines used are not expensive as compared to the ones used for HPHT lab grown diamonds.

Lab grown diamond suppliers and lab grown diamonds wholesalers thus find CVD diamond manufacturing more preferable.

This gets reflected in the market price rendering them almost 30-50% less priced than their natural counterparts. 

You, as a buyer are therefore getting immensely lucky here!

They come in a range of shades.

By default, CVD diamonds take a brownish hue. But with improvements in technology and innovations made, the brownish tinge is prevented giving colorless crystals. 

Colorless CVD diamonds are suitable to adorn rings or other pieces of jewelry due to their extraordinary aura.

But CVD diamonds give you even more incredible options. 

By supplying boron or nitrogen into the chamber, the colorless CVD diamonds can be transformed into blue or yellow ones.

Blue diamonds whether mined or not make beautiful adornments in jewelry pieces. But the mined ones are highly-priced as they are extremely rare. 

CVD diamonds are therefore better substitutes to natural colored diamonds. They cost less yet give you a wide variety of options.


CVD diamonds are beneficial in many ways. They give you better than what you are looking for at affordable rates. To know how pure and satisfying, they are, you need to see and explore them in person. We are ready to help you with that. Our amazing collection of CVD diamonds is waiting for you here. All you have to do is request a call and we will get in touch with you today!

What Makes CVD Diamond A Better Choice Than Others?

CVD diamonds are a type of synthetic diamond. Introduced as a much cheaper method of production than HPHT, which was the first method invented to produce man-made diamonds, the process is considered to be the most reliable method to produce synthetic diamonds today.

What are CVD diamonds?

CVD stands for Chemical Vapour Disposition. Unlike the HPHT method of making diamonds, CVD makes use of equipment that is less sophisticated rendering their cost of production less. For lab grown diamond manufacturers, this is a major reason why CVD diamonds are becoming increasingly preferable over others, even HPHT.

A diamond seed travels through the following steps before it becomes a complete CVD diamond:

  1. The diamond seed is placed inside a vacuum chamber.
  2. The temperature inside the chamber is increased up to more than 800 degrees Celsius.
  3. A carbon rich gas usually methane is then used to fill the chamber.
  4. With the effect of the high temperature, the gas gets ionized and the carbon particles break into fragments coating the diamond seed making it grow in size.
  5. This process will continue for a minimum of 2 to 4 weeks for the diamond to reach its final form.

Are CVD diamonds real diamonds?

Yes, CVD diamonds are real diamonds. They are the same as naturally derived diamonds. CVD diamonds only differ from mined diamonds in how they take origin.

When a natural diamond takes billion of years to reach its final stage, the same is achieved by a CVD diamond within a few weeks. But that does not mean they are less in quality, brilliance, or shine. They have the exact same chemical, physical and optical properties as that of a mined diamond.

Due to their similar characteristics, it is difficult to tell them apart from mined diamonds without the aid of experts and devices that can determine the minute attributes of the gems.

Are they purer than natural diamonds?

According to the CVD Diamond manufacturers in India, these gem-quality stones are crafted with care and craftsmanship that make them flawless and to a large extent free from inclusions or other marks.

Inclusions are the marks that mined diamonds develop in the process of origination. They are therefore the signatures left behind by the nature on these stones. Similarly, man-made diamonds also come with such flaws. But, here the intensity would be less.

A controlled atmosphere set up to reproduce the natural conditions that give birth to mined diamonds is apt for making gem-quality stones with minimal inclusions or flaws. From the temperature to the constituents that come into play, everything is done as specified on paper. Therefore, CVD diamonds are one of the perfect groups of diamonds you can find on the planet.

So, do they shine better?

Yes! It is not wrong to say that CVD diamonds shine better than their natural counterparts. However, generalizing the statement might be wrong. The minimal presence of inclusions or other similar attributes means a better pathway for the reflected rays of light resulting in the brilliance that can mesmerize the eyes of the beholder.

Diamonds are classified into different categories. Type II diamonds are the ones that are tested to be the purest among all. These categories are found both in natural and man-made diamonds. And CVD diamonds are no exception. If lucky enough, the CVD diamond manufacturer you approach might have a good collection of these exceptional gems.

But, CVD diamonds environment-friendly?

Oh, they are very much so! CVD diamond manufacturers in India and around the world are contributing to the well-being of mankind through the creation of these gem-quality beauties.

Mining has a lot of negative impacts– deforestation, landslides, chemicals that affect the soil, exploitation of human labor.

CVD diamond suppliers or manufacturers are providing you with products that are guilt-free. CVD diamonds are made in secure laboratories, far from the bosom of nature, where no human is forced to do vicious activities, no animals harmed nor their habitats destroyed. Hence, when you buy a CVD diamond, you are taking the better path. A path to conservation.

To wrap up

Going to buy CVD diamonds in India is like going to the field and plucking apples right from the trees -fresh and raw. Being one of the major lab-grown diamond manufacturers in the world, India has an amazing collection of CVD diamonds that are always in demand across the world. Make sure to approach the right diamond manufacturer who is can give you the guarantee that you are buying a real valuable CVD diamond.
