“白幽灵”水晶仿制品的鉴定特征

Identification Characteristic of Artificial Phantom Crystal

“白幽灵”水晶是一种含有较多白色矿物包裹体的水晶的商业名称,这种水晶的价值通常高于普通无色水晶。近期市场上出现了一种形似天然“白幽灵”水晶的仿制品。本文选取具有代表性的仿制品、天然“白幽灵”水晶样品及玻璃样品,采用常规宝石学测试、傅里叶红外光谱、拉曼光谱进行对比分析,发现仿制品中的白色包裹体与天然“白幽灵”水晶中的白色矿物包裹体成分不同,而与经过激光内雕处理的玻璃样品的包裹体具有相同特征。通过测试可知,天然“白幽灵”水晶样品中的白色矿物包裹体为白云石;样品仿制品主体为天然水晶,白色包裹体为经过激光内雕处理产生的多样化图案,具有一定的商业欺骗性,在鉴定和购买时应引起重视。

“White phantom crystal”is the trade name of crystal which contains white mineral inclusions.It’s more expensive than ordinary crystals.A kind of phantom crystals with artificial inclusions that is similar to natural phantom crystal has appeared in the market recently.After gemmological,FTIR spectra and Raman spectra tests,it was found that the white inclusions in the artificial phantom crystal are different from inclusions in the natural phantom crystal.The research results revealed that the white mineral inclusions in the natural phantom crystal samples are dolomite.The main body of the artificial phantom crystal samples is natural but the white inclusions in the samples are made by laser engraving.It is suggested to test the inclusions when identifying this kind of crystals.
