Abstract: The possibility and reliability of gemstone identification by the confocal-micro-Raman technique.Results show that it is easy to identify the false gemstone in bulk samples,while the measurements from small inclusions can provide valuable information on the origin of the gemstones.The FWHH of spectrum also can provide valuable information.It is found that the fluorescence spectrum recorded at the same with the Raman spectrum also has valuable information for the identification of the natural or synthetical.
