This 4.54 carat marquise lab grown diamond, a long, pointed outline that gives the most face-up size per carat. G color faces up white once set, the sweet spot between beauty and value. SI1 clarity keeps the price sensible while staying lively to the eye.

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.
