New York: Pure Grown, the man-made diamond company formerly known as Gemesis, is selling a 3 ct. K SI stone­—which it calls the largest colorless diamond ever produced by nonnatural means, reports jckonline.

Lisa Bissell, the Fabrikant veteran recently appointed president and CEO of the company, says that she has every intention of selling the gem, which has a report from the International Gemological Institute. “I don’t run a museum,” she says. She predicts it may fetch $21,000.

With Bissell taking over, the rechristened New York City–based company—owned by Suraj Mehta, son of Indian diamantaire Jatin Mehta—is solely devoted to sales and marketing.
