Increases the number of synthetic diamonds sold as natural.
Latest news from the world of diamonds: synthetic ones are more and more similar to the natural ones. So that now even the gemological laboratories are struggling to distinguish them. There are more and more undisclosed, so who assures you that you have the solitaire on her finger is authentic? The alarm does not come from gossip or talk that you read on social networks, but directly by the Gemological Institute of America, the most reliable analytical institute of precious stones. Gia, in fact, announced time ago that he had found on the market in Hong Kong a 5-carat undisclosed diamond, synthetic, with a quality that makes it difficult to distinguish from a real diamond. Not only so far synthetic diamonds were small, but 5 carat is a record.
Gia has classified the synthetic diamond with color equivalent to J and clarity VS2, ie comparable to a stone of high quality genuine.
No traces have been found, in addition, of black inclusions, which are often contained in the synthetic diamond. Experts of Gia argue that if the diamond was examined under a microscope would be classified as natural. It has been identified, however, only through a detailed spectroscopic examination: a fairly expensive technology, that those who buy precious stones could be considered superfluous.
This discovery casts a shadow on the market: how many synthetic diamonds undeclared are out there, they ask the experts of the GIA? India and China are the two most at-risk markets, but it is not impossible that even in Europe and the US arrive passed off as natural synthetic diamonds. The test statistics seem confirm these: the GIA has examined a stock of 3005 diamonds randomly selected. Of these three they have proven fake, i.e. synthetic. And a trader admitted that tolerance is 1-2% in the sale of synthetic diamonds undisclosed. A percentage that starts to be significant and could increase with time. Federico Graglia
