This specimen of well-crystallized Stannite from the Yaogangxian mine in Hunan, China features numerous groups of well-defined, brassy-colored Stannite crystals in association with several sharp and very clear Quartz crystals and a sprinkling of white Dolomite and Muscovite Mica. There is a lot of Stannite on this specimen; in fact, half of the matrix is composed of Stannite. It is not quite pristine (just a little damage at the periphery edges of the cluster) but is close to it. There is even a Stannite-lined vug on the right side of the piece. The Quartz crystals all have perfect tips, and some of them even contain Dolomite-covered phantoms in their terminations. Not only is this a very rare species, but to find it in such an aesthetic composition with three other well-crystallized minerals is wonderful. The stannite has excellent luster, and crystals to 8mm.
