贵翠又名绿色石英,以其色翠质坚而作为中档玉料使用。因此,对其物质成分、染色机制和地质成因的研究,将有助于扩大该种玉料的使用,同时在宝石矿物学研究中也具有一定的理论和实践意义。 一、 一般特征和地质产状 贵翠一般为绿色、淡绿色,次为翠绿、葡萄绿和胆矾蓝色。着水后色泽更鲜艳,致密块状,有时可见颜色深浅相间的条带状或花斑状构造。实测比重为2.63(纯石英的比重为2.65)。半透明或不透明。在强碘钨灯照射下或长期暴露于日光下,透明度有所降低,颜色也有所减弱。
Also known as Green Quartz Gui Chui, with its strong color of jade as mid-range jade use. Therefore, the study of its material composition, dyeing mechanism and geological cause will help to expand the use of this kind of jade material, and also has certain theoretical and practical significance in the gemmological study. First, the general characteristics and geology Gem-like green is generally green, light green, green times, grape green and gallstone blue. After the water more vivid color, dense block, and sometimes the color depth of the ribbon or piebald-like structure. The measured specific gravity of 2.63 (pure quartz specific gravity of 2.65). Translucent or opaque. In strong iodine tungsten lamp exposure or long-term exposure to sunlight, the transparency has decreased, the color also weakened.
