English: Fluorite, Dolomite, Quartz
Locality: Shangbao Pyrite mine, Leiyang County, Hengyang Prefecture, Hunan Province, China (Locality at mindat.org)
Size: 11.4 x 8.3 x 8.1 cm.
This fine piece features a pristine, 3.8-cm-across fluorite with intense green-purple zoning. No subtle phantom here. The crystal is one of the best and biggest of this style. It is pristine, complete, and totally translucent. The dolomite next to it is 6 cm. It is perched on both quartz and porcelain-like dolomite, making for a great contrast. This is from a new pocket found at the end of 2008. NOTE: these exhibit the photographic property of metamerism. They change colors from halogen and professional bulbs (more blue) to indoor fluorescent lighting and even natural sunlight (more green). Examples from both are shown here.
