He said in a company statement that, “the science and technology behind the processes synthesizing this stone are significantly more advanced than other man-made diamonds currently on the market.”
New Diamond Technology unveiled the stone at their booth during the recent JCK Las Vegas show.
It comes only two months after IGI Hong Kong certified a 5-carat radiant-cut brilliant and 4-carat-cushion-cut brilliant diamond also grown by New Diamond Technology that were, at the time, thought to be the world’s largest man-made diamonds.
