About Limelight Diamonds

Headquartered in Mumbai, Limelight Diamonds is India’s largest sustainable luxury brand offering lab grown CVD diamond studded jewellery.

Recently awarded the ET (Economic Times) Business Icon Award 2020 for Technology Leaders in Sustainable Diamond Creation, Limelight strongly advocates sustainable and conscious living that can maintain the diamond legacy yet preserve the planet for a future. As the leading sustainable brand in India, Limelight has been in the forefront of showcasing lab grown CVD diamond studded jewellery from India to the world.

Further, the brand allows customers to manifest Type IIa diamonds, which are the purest type of diamonds, devoid of any chemical impurities. Type IIa diamonds have been the most valued and rare kind of diamonds as less than 2% of world’s natural diamonds have been classified as the purest Type IIa.

Limelight has not only been successful in attracting the consumers and the trade but also most recently received great support from several of the Royal Families in India that have been inheritors to some of the most precious diamond jewellery in the past.

Birth of a CVD Diamond

Lab grown CVD Diamonds are REAL Diamonds grown by exactly replicating 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. 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 CVD diamonds are 100% composed of carbon and nitrogen-free. 98% of the world’s natural diamonds contain nitrogen. 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.

The shine, brightness & lustre of Type IIa diamonds are significantly better than any other diamond. 100% of CVD diamonds are composed entirely of carbon and are classified as Type IIa. As a result, the shine & brilliance of CVD diamonds is unmatched and rare to find in their mined counterparts.

 A thin layer of natural diamond is taken as the seed.

 The diamond seed is placed in the CVD plasma sector.

 The same environment is re-created in the CVD reactor.

 Carbon disintegrates to form layers on the diamond seed.

 This results in a rough diamond, same as a mined one.

 The cutting and polishing process is the same for both.

 CVD diamond is a Type IIa diamond; the purest type.

 It is 100% carbon composed with better shine and luster.
