有哪些罕见稀有的宝石?

 Painite,铝硼锆钙石,这是1951年在缅甸抹谷(Mogok)地区宝石砂矿中发现的新矿物。并以英国矿物学家Arthur C. D. Pain的名字命名。该矿物具体的化学成分不清,一般称为铝硼锆钙石或红硅硼铝钙石。矿物主要呈透明的暗红色晶体,很长一段时间,世界上最大晶体只有Pain收藏的一块重1.7克的标本。1957年,它被国际上确认为新宝石矿种。并于2005年被吉尼斯世界纪录收录为最稀有的宝石矿物,因为直到2005年,全球也只找到25个完整晶体。由于鉴定技术的进步与标本积累,发现铝硼锆钙石晶体的数量也增加到了原来的几倍,但仍然不足100个。而且,能被切割成高品质宝石的晶体或碎块数量仍旧极少。

 
Painite, a new mineral discovered in 1951 in the gemstone placer in the Mogok region of myanmar. It was named after the British mineralogist Arthur c. d. Pain. The specific chemical composition of the mineral is not clear, commonly known as alb zirconium calcium or red borosilicate alc calcium. The minerals are mostly transparent dark red crystals, and for a long time the largest crystals in the world were only a 1.7g specimen in the Pain collection. In 1957, it was internationally recognized as a new gem mineral. In 2005, it was listed by the guinness world records as the rarest gem mineral, because until 2005, only 25 complete crystals had been found in the world. Thanks to advances in identification techniques and the accumulation of specimens, the number of alb zirconium crystals found has increased several times, but is still less than 100. Moreover, the number of crystals or fragments that can be cut into high-quality gems is still very small.
