This 4.00 carat cushion lab grown diamond, softened corners and a pillowy, romantic sparkle. At F colour it sits at the very top of the scale: icy and completely colourless. VS1 clarity is eye-clean, with only minor details under a loupe.

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.
