The diamond follows one that Gemesis announced in April of a 1.29-carat, E color, VVS2 clarity, emerald-cut stone which the firm said at the time was the biggest, whitest lab-grown diamond.
Gemesis said in a statement that its inventory includes more than 1,200 VVS2 and VVS1 clarity grades More than 100 are VVS1, as well as a range of E and F color diamonds.
Gemesis also introduced pink lab-grown diamonds on its e-commerce site last month.
