红锌矿:罕见宝石级红锌矿空心晶体

【摘要】:Zincite红锌矿是一种锌的氧化物矿物,产于锌矿床方解石脉中,有“锌红柱石”之称。六方晶系,晶体呈空心锥状,但极其罕见,大多呈粒状晶体和致密块状集合体。颜色主要有橙黄色、褐红色和深红色等,红色因锰元素致色。主要产地有美国、波兰和纳米比亚等。透明宝石级红锌矿极为罕见。Zincite is found mainly as an accessory mineral in zinc ore deposits. It is also known as “red oxide of zinc”.Natural crystals are incredibly rare. When they do occur,they are orange to red in color and are often found as masses or grains of hollow, pyramidal crystals. The major sources are Namibia, Poland, USA.·红锌矿空心锥状晶体

Zincite

红锌矿是一种锌的氧化物矿物,产于锌矿床方解石脉中,有“锌红柱石”之称。六方晶系,晶体呈空心锥状,但极其罕见,大多呈粒状晶体和致密块状集合体。颜色主要有橙黄色、褐红色和深红色等,红色因锰元素致色。透明至不透明,金刚光泽至树脂光泽。折射率2.01~2.02,色散0.127,相对密度5.64~5.68,摩氏硬度4~5。主要产地有美国、波兰和纳米比亚等。

透明宝石级红锌矿极为罕见。锥状晶体为非常珍贵的收藏品。由于宝石具有高折射率、强色散,以及抛光后的金刚光泽,颇受收藏者的青睐。
