Lab Grown Diamonds Process


Lab grown diamonds are generally produced by two main methods, considered to be the very best in the industry: chemical vapour deposition or high-pressure, high-temperature methods. Using the best of technology at Classic Grown Diamonds, we ensure that every diamond we manufacture is 100% pure, while being Sustainable at the same time.

A CVD ("Chemical Vapour Deposition") diamond grown by microwave plasma technology is the highest-quality diamond, though it’s man made diamonds, with properties equal to or better than natural diamonds. They are grown in a highly-controlled environment, using advanced technical processes that replicate the natural method of diamond formation.

On the other hand, HPHT puts a pure, solid carbon source under high pressure and high temperature. In the presence of a catalyst, the pressurized and heated carbon crystalizes into a diamond. HPHT is sometimes used to improve the colour of mined or lab-grown diamonds.


Every diamond manufactured by us has been analysed and graded by either the Gem Certification and Assurance Lab (GCAL) or the International Gemological Institute (IGI). These two laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. With this certification, you can rest assured that our diamonds will display the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle.

At the same time, these diamonds will also be 100% Sustainable, while being cost-effective at the same time.

Are Lab Diamonds similar to real diamonds?

Although grown by scientists instead of created in the earth's crust, lab grown diamonds are absolutely real diamonds—they display the same chemical and optical properties as natural diamonds. Expert gemologists also have a tough time to tell the difference.

We have a wide collection of lab created diamonds (also referred to as Lab grown diamonds, solitaire diamonds, man made diamonds) which are chemically, physically and optically identical to 100% mined diamonds.

We also offer small loose diamonds at cheapest prices.
