SSEF distinguishes between three types of reports: Diamond Grading Report, Gemstone Report and Test Report. A Diamond Grading Report covers loose colourless to near colourless natural diamonds. A SSEF Gemstone Report is issued for a single loose gemstone, including coloured diamonds. Gemstone Reports are issued only for natural stones (no synthetic or imitation material). A SSEF Test Report is the most versatile identification document and is issued for mounted gemstones, pearls, jewellery, lots of gemstones, synthetic or imitation material. SSEF does not issue reports for rough stones and reserves the right not to issue a report for certain items.
