在鉴定<a href="http://www.chowsangsang.com">珍珠的质量</a>时，可参照以下各项标准: 体积: 圆形珍珠的体积以它的直径计算，而其他形状的珍珠则以其最短阔度计算，体积越大越罕有，价值也越高。 形状: 由于蚌分泌的珍珠质不同，所以形状也有差异，一般分为圆、米形、水滴形、小梨形及不规则等，当中以<a href="http://www.chowsangsang.com">浑圆的珍珠最为珍贵</a>。 皮光: <a href="http://www.chowsangsang.com">皮光</a>是指珍珠的外观，它的外表是否光滑照人，对光源是否能反射出一种迷人的晕色，这都是衡量皮光的标准。 <a href="http://www.chowsangsang.com">瑕疵: </a>鉴定珍珠表皮的质量，要看它有多少瑕疵，如凹痕、抓痕和花纹都会降低它的价值。
