This 8.55 carat cushion lab grown diamond, softened corners and a pillowy, romantic sparkle. At F 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, different only in origin, with none of the mining footprint.

Sold loose at 14.9 × 10.1 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 830661461, laser-inscribed on the girdle, and shipped insured from Surat.
