This 1.66 carat round lab grown diamond, cut with 57 facets to return the most light of any shape. Its fancy black color is saturated and even across the stone.

It is chemically, physically and optically identical to a mined diamond: a lab created, man-made diamond in origin only, with none of the mining footprint.

Sold loose, it is ready to become an engagement ring stone, a pendant or a one-of-one piece. Independently graded and certified, and shipped insured worldwide from Surat.
