2007 GIA 都提供人造鑽石證書了
GIA 當初為了人造鑽石也是很緊張 ~
後來發現珠寶級的人造鑽石比自然鑽更天然無暇
所以就用此來分別 ~ 只是那間美國公司很低調神秘都用在其他特殊用途
所以對珠寶界衝擊也不大
De Beers 從之前近乎壟斷
到現在鑽石礦產擁有率剩 40%
早已經不再是以前的老大哥
鑽石之所以珍貴不就是靠著之前 De Beers 刻意封礦限量開採壟斷定價
話說 De Beers 旗下投資的ㄧ間子公司就是在做人造鑽石的
技術也是非常好 雜質隨便都可以做到小於 1ppm
光學級就更佳了 ~ 只是礙於策略問題不做珠寶的用途而以
現在 De Beers 經營權易主 勢力又不若以往
很難說未來會怎樣 ....
