Radiant Cut Lab-Grown Diamonds
Certified lab-grown radiant cut diamonds, each with an independent grading report. Lab-grown diamonds are chemically and optically the same as mined ones and cost far less per carat, so the same budget buys a larger or finer stone.

Each stone has a grading report from IGI or GIA, with the report number laser-inscribed on the girdle. The report is linked on every diamond page.
