摘　　要：近年来,天然玻璃作为宝石材料在市场的销售开始慢慢增多。由于天然玻璃和人造玻璃的主要成分都是二氧化硅,且都是无内部固定结构的材料,使得二者难以区别。文章通过常规的宝石学特征测定,同时利用偏光显微镜下的薄片分析和电子探针等手段对于天然玻璃的一种——黑曜岩和现今市场上出现的仿制品进行了物理性质和化学方面的对比。In the past few years,natural glass is increasing as one kind of gemstone materials in the market.For the main component of natural glass and man-made glass is silicon dioxide,and both of them have no defined crystal structure, it is hard to distinguish from each other.By using the regular gemological identification as well as polarizing microscope analysis and electron probe etc,the article has mainly contrasted the physical properties and the chemical composition of one kind of natural glass-obsidian and its replica which appears in nowadays market.
