Study on Gemological and Mineralogy Features of Huanglong Jade
The Huanglong jade of Zhenan, Xiaoheishan, Supa river these three fields in Longling Yunnan were detected by general gem identify instruments. The Mohs hardness is 6.5-7, relative density is 2.60(+0.10, -0.05)g/cm3 and the refractive index is 1.53±. The electron probe backscatter atlas of samples shows that Huanglong jade is a kind of cryptocrystalline mineral aggregation. Using electron probe and X-ray spectrometer tested different field samples, got that the main chemical composition of Huanglong jade is SiO2, furthermore, including same trace elements as K, Cr, Fe, As and so on. Finally judged that Huanglong jade is a kind of cryptocrystalline (or micro show crystal) mineral aggregation which mainly formed of SiO2, named yellow chalcedony (Huanglong jade).
