(IDEX Online News) – Gemesis, a major maker of gem-quality lab-grown diamonds, is offering what it says is the purest Type IIa and largest white diamond currently achieved for sale.

 

The diamond is a princess-cut stone that weighs 1.78 carats, is G color, and SI1 clarity.

 

It is certified by the International Gemological Institute (IGI).

 

The latest stone follows the announcement by Gemesis in April of a 1.29-carat, E color, VVS2 clarity, emerald-cut diamond, which the firm said at the time was the world’s largest, whitest lab-grown diamond.

 

Gemesis said its current inventory includes more than 1,200 VVS2 and VVS1 clarity grades – with more than 100 being VVS1, as well as a range of E and F color diamonds.

 

Gemesis also recently introduced pink lab-grown diamonds on its e-commerce site last month.
