This 6.57 carat marquise lab grown diamond, a long, pointed outline that gives the most face-up size per carat. At F colour it sits at the very top of the scale: icy and completely colourless. VVS2 clarity: inclusions are nearly invisible, even to a grader.

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.
