珍珠是一种古老的有机宝石。主要产在珍珠贝类和珠母贝类软体动物体内;而由于内分泌作用而生成的 含碳酸钙的矿物(文石)珠粒,是由大量微小的文石晶体集合而成的。根据地质学和考古学的研究证明,在两亿年前,地球上就已经有了珍珠。中国是世界上名副其实的珍珠古国,有关珍珠的记载可以追溯至公元前2200年。国际宝石界还将珍珠列为六月生辰的幸运石,结婚十三周年和三十周年的纪念石。


关于瑕疵


作为不需要加工就生成并带有神奇生命力的珍宝,100%完美无瑕的珍珠理论上是不存在的,因为即使是肉眼难以看见,借助10倍甚至更高的放大镜,还是可以看到珍珠表面生长的纹路、凹凸不平。从实践的角度来看,确实有一些珍珠用肉眼几乎看不到或者极难看到任何瑕疵,在商业应用领域,业内专家将之称为无瑕。国家标准的《珍珠分级标准》里面,对“无瑕”的定义是“肉眼观察表面光滑细腻,极难看到瑕疵”。 大多数养殖珍珠表面或多或少都会有螺纹,凹点等瑕疵。这也是古话所说“无瑕不成珠”的理论根据。
