説明

  The author has been dedicated efforts to accuracy improvement of gemstone identification by incorporating mineralogical aspects into traditional identification techniques. To cope with technological developments of synthetic gemstones and treatments, the author also applied various analytical laboratory techniques into gemstone identification. For instance, infrared spectral analysis is useful to classify diamonds into each type, distinguish natural stones from synthetics and detect impregnated materials such as resin in gemstones. CL method can be used to reveal growth history of a diamond crystal and this is applied to distinction between natural and synthetic diamonds. PL analysis is an effective technique to detect HPHT treatment in diamonds, while LA-ICP-MS analysis is effective to detect light elements such as Be that may be doped in corundum and it also can be applied to origin determination of gemstones such as corundum, emerald and tourmaline.<br>
