Diamond Services reports a lowering threshold for synthetic diamonds, as man-made stones as small as 0.0025 cts. discovered in New York
Multiple single-cut diamonds, sized from a quarter point to half a point (0.0025-0.005 carats), which were contained in jewellery recently submitted for testing to a Diamond Services laboratory, have been found to be synthetic, greatly expanding the range of goods that can be considered at risk of improper and deceptive disclosure.
