金绿宝石金绿宝石chrysoberyl晶体属正交(斜方)晶系的氧化物矿物,化学成分为BeAl2O4。化学式类同于尖晶石,故也称为铍尖晶石,但其晶体结构与晶形都相似于贵橄榄石(橄榄石)。晶体常呈厚板状;经常形成心形双晶或假六方的贯穿三连晶。具良好的柱面解理。莫氏硬度8.5,比重3.631~3.83。透明,玻璃光泽,呈或深或浅的绿色或黄至棕色。一种含微量Cr3+而在日光下呈绿色,在透射光和在烛光等人造光下呈红色的变种,称为变石,在中国宝石业中称翠绿宝石;另一种呈浅绿色并因含许多显微空洞和平行分布的针状包裹体而具蛋白光和活光的变种,则称为金绿猫眼石,因主要产于斯里兰卡而又称东方猫眼和锡兰猫眼。普通的金绿宝石是制作廉价宝石的原料,但变石和金绿猫眼石则是极为珍贵的宝石材料。金绿宝石主要产于花岗伟晶岩、细晶岩和云母片岩中;也作为碎屑矿物见于砂砾层中。世界上最主要的金绿宝石产地是巴西的米纳斯吉拉斯,而俄罗斯的乌拉尔,斯里兰卡分别是变石和金绿猫眼石的著名产地。金绿宝石亦可由焰熔法人工合成,但作为宝石材料,其质量远逊于天然晶体。金绿宝石
