Lab grown diamonds

Diamond that are light on the pocket


Diamonds are the hardest substance on Earth, with a Mohs scale of 10. The number 9 on the Mohs scale, Corundum, is 4 times lesser dense than diamonds. Due to this hardness, diamonds are extremely resistant to scratching and fracturing. These qualities of diamonds make it favourable to be used for cutting, grinding, shaping and polishing other hard materials including other diamonds. Notwithstanding its qualities, diamonds are technically formed of a single element-Carbon, just like the graphite of our pencils but with a high melting point of 3815 Degrees Celsius. Almost all natural diamonds contain impurities, in the form of slight colour differences due to presence of other elements like Boron and Nitrogen which give them blue and yellow colours respectively. Diamonds which have been exposed to radiation generally are green in colour.

Polished Diamond


We, at Riddhi Corporation, have been a pioneer in producing lab-grown diamonds since 2014. We have a dedicated Research and Development department of 15 specialists which was set up 11 years ago and which has set itself a target of growing diamonds up to 50 carats within 1 year.

We always strive to ensure that our diamonds are of consistent quality. We intend to ensure uniformity in quality by releasing an assortment of similar quality diamonds every month for sale. Currently, we sell both raw and polished lab-grown diamonds. Additionally, we are also in the business of manufacturing jewellery only on order basis.

We intend to popularize lab-grown diamonds for their benefits and price competitiveness.

We are currently involved in the business of the production, manufacture and sale of both Type 1 and Type 2 diamonds.


Industrial diamonds are renowned for their thermal conductivity and hardness. The 4C gemological criteria are irrelevant for industrial diamonds. About 80% of mined diamonds are unsuitable for use as gems, and are used for industrial use. The hardness of industrial diamonds is primarily used for cutting machinery and the like.

Synthetic diamonds have been in production since the 1950s. Even before that, numerous western scientists have tried to create artificial diamonds. It is estimated that about 98% of the diamonds used for industrial purposes are synthetic. It is a common misconception that synthetic diamonds are of inferior quality, but in reality they contain almost all of the qualities of real diamonds.

High Pressure High Temperature diamonds are made when a high purity carbon source and a solvent metal are introduced to diamond seeds and pressed at a high temperature of above 1400 Degrees Celsius. The resultant diamonds are much easier to cut as they are manufactured according to predetermined specifications.

Chemical Vapour Deposition diamonds are made when circumstances are created to make carbon atoms in a gas to settle in a substrate in a crystalline form. Synthetic diamonds made with these processes have qualities like hardness, thermal conductivity and electron mobility which can be far superior to those of naturally occurring diamonds.

Lab grown diamonds are eco-friendly, cause no impact on the environment or any kind of pollution and are of much better quality than mined diamonds. Due to these qualities, lab-grown diamonds are known as ‘green diamonds’. The difference between mined and lab-grown diamonds is indistinguishable to the naked eye, only a trained gemologist using specialized equipment can spot the difference.

The colour of the diamond is a result of impurities in the diamond. As mentioned earlier, certain elemental impurities give diamonds distinctive colours. Diamonds are graded on a scale of D to Z depending on the depth of the colour. Coloured fancy diamonds are extremely sought after and they are sold for high prices at auctions.

Diamonds have always been treasured for their clarity, beauty and opulence. Traditionally worn by nobility, diamonds are now used for a variety of new uses, besides being used for jewellery. Presently, diamonds come from two sources-mined diamonds and lab grown or green diamonds.

A diamond is valued by 4C’s-Cut, carat, colour and clarity. Diamonds are measured in a carat which is the mass of the stone, with 100 grams indicating 1 carat and so on. A diamond is cut to enhance its faceted look, thereby losing some of its carat value. The proportion, symmetry and polish of a diamond affect the quality of its cut.


The difference between mined and lab-grown diamonds is indistinguishable to the naked eye, only a trained gemologist using specialized equipment can spot the difference. The price difference between mined and lab-grown diamonds is in the range of 30-70%, with lab-grown diamonds being cheaper and free from impurities.

It is a common misconception that lab grown diamonds are of inferior quality, but with advanced technology, they are made of even better quality than mined diamonds. There is also the misplaced notion that diamonds are expensive due to polishing and other processes. But as lab grown diamonds are made from scratch, it is relatively cheaper. Due to the price difference as well as the superior quality, lab-diamonds are being increasingly preferred over mined diamonds.

The difference between mined diamonds and synthetic diamonds are poorly defined, and their use depends upon market conditions, where slowing demand for industrial diamonds is substituted for gemstones and vice versa.90% of industrial grade diamonds are currently produced in China. The hardness of industrial diamonds is primarily used for cutting machinery and the like.
