瑞士古柏林宝石实验室编号17031059报告,鉴定9.14克拉枕形主石为天然祖母绿,颜色为绿色,产地哥伦比亚,微注油,2017年3月23日。
哥伦比亚最主要的两处祖母绿矿床是木佐(Muzo)和契沃尔(chivor),它们分布在波哥大东北约100km范围内,地处科迪勒拉山脉之中。由于矿区处于崎岖的山区,开采十分艰难,产量尤为稀少,如今的产量亦大不如前,这也是导致了哥伦比亚祖母绿的价格迅速攀升的重要原因。其中产自木作矿床的祖母绿颜色最为纯正鲜艳,在市场上可以被称之为「木佐绿」的祖母绿宝石十分珍贵,价格亦十分昂贵。
注:在刚刚结束的2016年香港苏富比秋拍中,一颗重约22.21克拉哥伦比亚木佐微注油的祖母绿戒指以230万港币成交,平均每克拉约为9万人民币。
