Lapis Lazuli Cabochon素面青金石

An original stone from the new mine of Onh Bin Yee Htwet, near the Mogok valley. This lapis differs from the typical burmese one, wich is from the Dattaw valley, because of his composition : nearly free of pyrite, the higher part of this sample has a lighter royal blue color wich must be composed of lazurite, and the rest of the surface of the stone has a darker deep blue color, with a more included structure, wich must be composed of sodalite (the specific gravity of the stone is 2.68, too high for pure sodalite). Even if the shape is not regular, the piece is large, the polish is good, and the structure is very original. A collector stone. (GK)

这颗200多克拉的青金石来自于缅甸抹谷附近的新矿区---Bin Yee Htwet 

这块青金石不同于普通常见的地方在于，它是来自缅甸的而它本事几乎没有黄铁矿。石头的顶部些皇家蓝的颜色，是来自于青金石矿，还有的地方伴有深蓝色的方钠石。形状和抛光打磨都不错，是值得收藏的矿标。
