A Russian laboratory-grown diamond manufacturer, New Diamond Technology, is claiming it has produced a 5.11-ct diamond, the largest man-made, polished, near-colorless stone ever produced.
According to the manufacturer, the unenhanced radiant-cut type ‘IIa’ diamond, produced by the high-pressure, high temperature method (HPHT) bears a K SI grade but hasn’t yet been sent to a lab.
This process is called Microwave Plasma Chemical Vapor Deposition, where carbon atoms are layered on top of an initial diamond ‘seed,’ fast-tracking a natural process lasting many millennia to a matter of months. And because these stones are lab-made, they’re good for the environment and are free of the ‘blood diamonds’ stigma that’s so tainted their traditionally-mined counterparts.
Diamond Experts familiar with diamond growing, say that it is an impressive achievement, but wondered whether it could be repeatable and also questioned what the stone would fetch commercially.
New Diamond Technology says it has a “new approach” that allows it to produce lab-grown gems with higher colors and clarity from its factories in Russia and Hong Kong. It said that it can produce gems ranging from 4 to 11 carats.
Company President Tamazi Khikhinashvili says that their diamonds are “more affordable” as compared to natural diamonds. He says the company has sold lab-grown gems to customers in Europe, Asia, and the United States.
Jewelry worn by famous peoples has always been mesmerizing. So this time in honor of President’s Day that we celebrated recently, we thought why not come up with jewels worn by first ladies of past and present. After all we all can take a few lessons in style, or at the very least marvel at.
