摘要: 对各种颜色的塔希提黑珍珠进行了系统的拉曼光谱测试,结果表明,塔希提黑珍珠的拉曼光谱反映了两类物质的存在,即文石矿物和黑色色素,虽然目前难以确定黑色色素的具体成分,但其拉曼光谱仍可作为黑蝶贝产珠的鉴定依据。

Abstract: The Raman spectra of various Tahitian black pearls have been tested, from which two kinds of substance are found, one is aragonite, the other is a kind of black pigment Even though the exact chemical compositions of the black pigment are not known, the spectra can be applied to the identification of pearls from Pinctada magaritifera.
