CVD Diamond Supplier in India — Nishal Gems
Nishal Gems is a premier CVD diamond supplier based in India, catering to jewelers, wholesalers, and retailers across India, the USA, UAE, UK, Europe, and beyond. We specialize in Chemical Vapor Deposition (CVD) diamonds — one of the most advanced and popular methods for creating lab grown diamonds today.
Our CVD diamonds are grown using cutting-edge reactor technology, resulting in stones with exceptional clarity, brilliant sparkle, and consistent quality — batch after batch.
What is a CVD Diamond?
CVD (Chemical Vapor Deposition) is a process where a diamond seed is placed inside a chamber filled with carbon-rich gas. The gas is ionized into plasma, and carbon atoms deposit onto the seed, gradually forming a full diamond crystal.
CVD diamonds have rapidly become the industry's preferred method because:
-
They produce diamonds of superior purity (Type IIa quality)
-
They can be grown in larger sizes with fewer inclusions
-
They are highly consistent in color and clarity
-
The process is more energy-efficient and environmentally friendly
Nishal Gems produces and supplies premium CVD diamonds that meet international gemological standards and arrive with full certification.

Ans- Yes. All Nishal Gems CVD diamonds are certified by leading institutions including IGI and GIA.
Q-3: Do you supply CVD rough diamonds?
Ans- Yes. We supply both rough CVD diamonds and polished finished CVD diamonds depending on your needs.
