A glassy cubic crystal of fluorite 3.0 cm on edge, this very dark in color due to rich inclusions of metallic acicular boulangerite. This is a twinned crystal grouping, and is set on a cluster of crystallized quartz. In very good condition.The Yaogangxian mine, located in Yizhang County within Hunan Province, China, was officially discovered in 1914 and immediately went into active production as a major industrial source for tungsten and tin. While it has operated commercially for over a century, it gained international renown among mineral collectors beginning in the late 1990s for yielding world-class crystal specimens. Geologically, the deposit is situated in the Nanling metallogenic belt and consists of high-temperature hydrothermal vein systems hosted primarily within Mesozoic granitic intrusions and older sedimentary strata. These granite-derived veins host rich associations of tungsten and tin ores alongside open cavities that produce exceptional aesthetic minerals like fluorite, quartz, and various sulfides.
