天然玻璃翠观音吊坠（收于2018年）玻璃翠，化学成分为二氧化硅; 质地通透,肉眼下几乎无杂质,颜色鲜艳而均匀。因其具有鲜艳的绿色和较高的透明度，而被称作"冰翠"。其成因很多：比如岩浆喷出成因、陨石成因等。1844年，达尔文在澳大利亚得到一块火山喷发形成的喷出物，后世称之为达尔文玻璃。18世纪时有人认为它们是史前人类制造的玻璃遗迹，后来又有人猜测它们是雷电的产物。科学家奥基夫认为是3400万年前月球上的一次火山爆发，飞溅出许多碎石，其中部分碎石跌下地球而形成的。玻璃翠在地球上并非随意散布，而是有"选择性"的，主要集中在南北纬50度之间的部分地区。

此吊坠，沉甸甸，绿幽幽，微透明，摩氏硬度为5～6。在偏光镜下均质体，略显明暗变化，这主要是由基质中的微晶造成的。放大检查：略见细微圆形气泡；有"雏晶"包体存在。精湛的雕工和优美的造型成就了它的独一无二。 Glass green, chemical composition of silica; transparent texture, almost no impurities under the naked eye, bright and uniform color. Because of its bright green and high transparency, it is called "bingcui". There are many causes, such as magmatic eruption, meteorite genesis, etc. In 1844, Darwin got a piece of ejecta from a volcanic eruption in Australia, which was later called Darwinian glass. In the 18th century, some people thought that they were glass relics made by prehistoric human beings. Later, others speculated that they were the products of lightning. The scientist O'Keeffe believes that it was formed by a volcanic eruption on the moon 34 million years ago, which spattered a lot of debris, some of which fell to the earth. Glass green is not scattered randomly on the earth, but selective, mainly concentrated in some areas between the north and South latitudes of 50 degrees.

The pendant is heavy, green and transparent, with a Mohs hardness of 5-6. Under the polarizing microscope, the homoplasm shows a slight light and dark change, which is mainly caused by the microcrystals in the matrix. Magnifying examination: slight round bubbles and "rudimentary crystal" inclusions were found. Exquisite carving and beautiful modeling make it unique.
