IDENTIFICATION OF NATURAL, SYNTHETIC AND PLASTIC SIMULATED OPALS

摘要: 通过常规宝石学测试、X荧光光谱分析、红外吸收光谱分析和热曲线分析，研究了天然欧泊、合成欧泊和塑料欧泊的物理化学特征和谱线特征，从而提出了相对密度值、红外5851，5730，4700，1730cm－1吸收峰及4400～3700cm－1处吸收带、微量元素Cl，Zr等是欧泊天然品和合成品的主要鉴别特征，同时也证明了吉尔森合成欧泊的含水量远远低于天然欧泊。

Abstract: This article describes the examination of natural, synthetic and plastic simulated opals by basic gemmological testing, X-ray fluorescence analysis, infrared absorption spectra and thermal analysis. Specific gravity, 5 851, 5 730, 4 700, 1 730 cm^-1 infrared absorption spectra and trace elements CI, Zr etc are main characteristics for identifying natural opal and various synthetic opals. T he characteristics mentioned above also prove that Gilson opal is far lower than natural opal in water content.
