摘　　要：研究了化学优化处理前后合浦珍珠的宝石学特征及影响珍珠质量的因素．提出了珍珠具多元构造的特征．珍珠久置变黄及优化后珍珠返黄是由于珍珠中有机物质和变价微量元素等受侵蚀氧化分解所致．In this paper, the gemological characteristics before and after bleaching and the quality control factors of Hepu cultured sea pearl were studied. Hepu pearl consists of pearl nucleus, organism layer, aragonite layer and outside layers etc., rather than simply bilayer structures formerly believed. And the yellow color of Hepu pearl is mainly caused by the oxidation of trace elements and organic materials.
