5.3" Green, Octahedral Fluorite on Milky Quartz - Inner Mongolia

This fascinating specimen features a milky quartz crystal with green, octahedral fluorite crystals, some of which have deep blue cores. It comes from the Huanggang Fe-Sn Deposit in Inner Mongolia and is accompanied by an acrylic display stand to assist with presentation.

Under short-wave UV light, the fluorite crystals exhibit purple fluorescence.

The "Huanggang Mine" is a complex of seven somewhat interconnected mines that are located near Chifeng City, Inner Mongolia, China. Incredible mineral specimens started coming out of this mining complex around 2009, however, the location provided for the specimens was a long ways away from the actual site. This is a practice commonly performed by dealers/miners following a new discovery to try and preserve the mineral site's true location, and/or for political purposes.

As the popularity of the site increased, more and more fascinating specimens were popping up on the market. Some of the earlier minerals included world-class ilvaite crystals, pink fluorite octahedrons, hedenbergite included quartz (many of which were discarded at first) and arsenopyrite. Over the following years, garnets, pink manganoan calcite, gorgeous fluorites, sphalerite, löllingite, borcarite, scheelite and a variety of other minerals began to surface on the market. To this day, new mineral discoveries are made in these mines.
