Abstract：X-ray fluorescence spectrometer is mainly used to measure the composition and content of precious metals in the jewelry laboratory. It has the characteristics of wide analysis range and high analysis accuracy. The main elements in gemstones are determined by X-ray fluorescence spectrometer to identify gemstones with similar appearance. Distinguish the subspecies of gem minerals by measuring the trace elements in gemstones. In addition，it also introduces the identification of the origin and occurrence of gemstones，the identification of synthetic gemstones， and the identification of optimized gemstones.

Key words：X-ray fluorescence spectrum；synthetic optimization；gem identification
