This 1.55 carat round lab grown diamond, cut with 57 facets to return the most light of any shape. At E 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. Cut to ideal proportions for maximum brilliance.
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.
