3.85" Seafoam-Green, Cubic Fluorite (Large Crystals) - Huanggang Mine

This specimen features cubic fluorite crystals that formed from a quartz crystal encrusted matrix. It was collected from the Huanggang Fe-Sn Deposit in Inner Mongolia, China. The fluorite crystals are relatively large, well formed and bear a seafoam-green coloration. This unique color is a result of multiple layers of alternating colors, including blue, green and purple. These colors are best seen by backlighting the fluorite crystal.

The entire specimen measures 3.85 x 2.7" and the largest fluorite cube is about 1.5" wide.

The "Huanggang Mine" is a complex of seven somewhat interconnected mines 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 and miners following a new discovery to try and preserve the mineral site's true location, and/or for political purposes.

As the site's popularity 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 often made in these mines.
