The Gemetrix Jewellery Inspector allows observation of the SW and LW UV reactions, including phosphorescence, of diamonds set in jewelry or loose. It is very useful for ID of synthetic mounted diamonds when used with booklet on “Fluorescence as a tool for Diamond Origin Identification”, while a smart phone camera can be used to capture images. A special tray holds rings, pendants and other jewelry under the viewing area. Its compact and portable design gives it a small footprint on a counter.
