Birth Of A Limelight Diamond

Limelight diamonds are REAL diamonds grown using a process called Chemical Vapor Deposition that exactly replicates the diamond creation process from under the surface of the earth.

It all begins with a natural diamond seed.

The seed is placed in the CVD plasma chamber and an intense environment of temperature and pressure is created just like that found under the earth. Gases are infused and along with the right combination of pressure and temperature conditions, carbon formations develop into rough diamonds.

The chemical, thermal, optical, and physical properties of these diamonds are identical to that of natural diamonds – same size and same 4C’s- Cut, Colour, Clarity, Carat. This is exactly like the test tube baby technology where the DNA remains the same but just grows in a different environment. As a result, you can never differentiate between a test tube or a natural born baby. You cannot call it fake or artificial.

Since they are not found in mines, CVD diamonds add another C to their definition – of being Conflict Free. But one main significance is that unlike 98% of the world’s natural diamonds containing nitrogen, Limelight’s CVD diamonds are 100% carbon-composed and nitrogen-free. Only 2% of the world’s natural diamonds are the purest type, 100% carbon composed. World-renowned diamond grading & certifying labs classify these diamonds as Type IIa.

Our process

  • 01

    A thin layer of natural diamond is taken as the seed

  • 02

    The diamond seed is placed in the CVD plasma reactor

  • 03

    The same environment is re-created in the CVD reactor

  • 04

    Carbon disintegrates to form layers on the diamond seed

  • 05

    This results in a CVD rough diamond, same as a mined one

  • 06

    The cutting and polishing process is the same for both

  • 07

    CVD diamond is a Type IIa diamond; the purest type

  • 08

    It is 100% carbon composed with better shine and lustre

OUR STANDARDS

All Limelight diamonds are Type IIA. They are purely made of carbon and do not contain any nitrogen impurities. The shine, brightness & lustre of Type IIA diamonds are significantly better than any other diamond.

A Type IIA diamond in the mined counterpart is an extreme rarity as 98% of world’s mined diamonds have nitrogen impurity and are not the purest. As a result, the shine & brilliance of CVD diamonds is unmatched and rare to find in their mined counterparts. Our Koh-I-Noor was a Type IIA, nitrogen free diamond as well and was not only famous for the sheer size but also its flawless lustre!
