This 4.01 carat emerald lab grown diamond, long step-cut mirrors and a calm, architectural glow. At D color it sits at the very top of the scale: icy and completely colorless. 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.
