About Padparadscha

帕帕拉恰（莲花刚玉）是刚玉（蓝宝石）中最为稀有且最受追捧的品种，展现出独特的粉橙色至橙粉色，让人联想到莲花花瓣或斯里兰卡日落的色调。名称来自僧伽罗语中的「lotus flower」（莲花）。帕帕拉恰的颜色必须同时含有粉红和橙色成分，缺一不可——过于偏橙则归入橙色蓝宝石，过于偏粉则归入粉色蓝宝石。斯里兰卡（锡兰）是传统上最受认可的产地，该产地出产的帕帕拉恰因其精妙的粉橙平衡色调在宝石界享有最高声誉；此外，坦桑尼亚（翁巴矿区）和马达加斯加也出产品质上乘的帕帕拉恰。折射率1.762至1.778，摩氏硬度9，顶级品质可达每克拉数千至数万美元，是世界上价值最高的宝石品种之一。
