CVD diamonds have the same physical, chemical and optical properties as mined diamonds. The only difference between lab-grown and earth-mined diamonds is their origin. is their origin. CVD diamonds are faceted and polished by the same highly skilled diamond cutters who facet and polish mined diamonds.

We are one of the largest and biggest Manufacturers and Suppliers of Loose Rough CVD Diamonds and Loose Polished CVD Diamonds which is also known as Lab Grown Diamond, Synthetic diamond, HPHT Diamond, Man-made-diamonds, and Supply to more than 40 Countries from India.
