This 4.28 carat square cushion lab grown diamond, a distinctive outline cut by hand on our Surat bench. At E color it sits at the very top of the scale: icy and completely colorless. 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.
