It's not a deja vu, this is the question already asked by the International Gemological Institute experts about a year ago when they were given lots of undisclosed synthetic diamonds for grading. A number of gems was record – 600 items at a time. Before IGI dealt with synthetic diamonds but with no more than a couple of stones. Logically, the reaction to such a situation was too more fast and publicized. Even though there is a number of compact diamond detecting tools it's still impossible to differentiate synthetic diamonds from natural stones. They look identical.
It sounds like somebody marked that well and took advantage of top-notch quality of synthetic diamonds again! There are two victims this time: the Japanese diamond company and the Mumbai-based diamond trader. Both claimed to buy parcels of original polished diamonds but a half of them were detected as 'synthetic'. There is low chance a diamond detecting tool has been broken in both companies.
The problems is synthetic stones are mixed with natural and get in circulation. Since synthetic diamonds are 100% real but for their origin, it's hard to distinguish them. As a result, they can be easily mixed and sold to diamond export companies, what actually has been done.
Such case is just another motive for the Rapaport Group and Martin Rapaport in particular to raise diamantaries' awareness concerning synthetic diamonds. This is actually the most talked-about issue of his conferences for the lastcouple of years. So we are to expect a five-day Gem-A conference next month focusing on synthetics.
But even in the bad the good can be found: isn't that just another prove synthetics are as good as mined?
