“De Beers made a brilliant move. They’ve completely upended the lab-grown diamond business. When a company can make large-sized lab-grown diamonds and produce them quickly, they will control the market. If you factor in all the producers of lab-grown diamonds, this pre-JCK Show announcement – which was also incredible timing – may take lab-grown diamonds down the same path as cubic zirconia. When CZs hit the market, they were $200 to $300 per stone. Now they’re dollars per stone, and that’s for the better ones.
