Pioneering Atomic Purity & Master Diamond Craftsmanship

Headquartered in Surat, India—the heart of global diamond manufacturing—Colar Diamond grows Type IIa CVD diamonds engineered to perfection.

Our Story & Science

From Atomic Plasma Seeds to Certified Solitaires

Colar Diamond was founded to bridge high-energy materials science with global luxury jewelry wholesale. By housing our MPCVD (Microwave Plasma Chemical Vapor Deposition) growth reactors directly in Surat, we control every microscopic phase of diamond creation.

Only 1-2% of all natural diamonds possess Type IIa chemical purity (devoid of measurable nitrogen impurities). At Colar Diamond, 100% of our CVD production achieves Type IIa single-crystal lattice perfection.
