Stannite with Arsenopyrite

Item Description

The Yaogangxian Mine has produced the finest crystals of Stannite in the world, both in terms of size and quality. This piece is a nice association specimen that was mined in the early 2000s featuring attractive, dark brass-black colored clusters of Stannite measuring to around 2-3 mm, associated with bright metallic silvery groups of Arsenopyrite measuring up to 8 mm, and I can see some little groups of silvery-beige Muscovite for a nice touch.
