This 1.40 carat round lab grown diamond, cut with 57 facets to return the most light of any shape. 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. Cut to ideal proportions for maximum brilliance.
It is chemically, physically and optically identical to a mined diamond, different only in origin, with none of the mining footprint.
Sold loose at 7.1 mm face-up, it is ready to become an engagement ring stone, a pendant or a one-of-one piece. Graded by IGI under report 770629705, laser-inscribed on the girdle, and shipped insured from Surat.
