New York-based Diamond Services laboratory reports that it has found “multiple single-cut [synthetic] diamonds”, sized from 0.0025 to 0.005 carats, set in several pieces of jewelry.
According to IDEX Online, the synthetic diamonds in the jewelry were removed from the eight rings in which they were set and sent for “full analysis at Diamond Services’ facility in Hong Kong”. There, they were tested with Diamond Services’ DiamaTest system, then re-examined with the DiamondView system of De Beers’ International Institute of Diamond Grading & Research (IIDGR) and Diamond Services Mini Raman Spectrometer.
Jospeh Kuzi, Diamond Services founder and managing director, commented: “To the best of my knowledge, this is the first time that a synthetic single-cut stone has been detected mounted in jewelry […] What this means is that almost no diamond can be taken at face value”.
