Stibnite in Quartz

Smokey Quartz sphere included by Stibnite crystals. I normally don't purchase polished specimens, however this was too unusual to pass up. Having grown up in California, I have admired the Stibnite in Quartz crystals from a deposit in nearby Nevada, the only locality I am aware of where Stibnite occur within Quartz crystals, until now. The Nevada crystals rarely even reach the diameter of this sphere, indicating the potential for some large Stibnite included Quartz crystals from China. The Sibnite in the sphere forms nice sprays, many with yellow coatings of Stibconite. Sphere is a little over 7.5 cm, about the size of a baseball.
