Cassiterite in Muscovite, Pingwu, Sichuan, China

I have offered a few excellent Chinese cassiterites previously but this the biggest and best yet! The main cassiterite is 3.5 cm x 5 cm by itself and perches confidently on top of a bed of muscovite mica. At first glance this crystal almost appears damaged but is actually a complex aggregate with multiple faces and terminations. The cassiterite's luster is excellent. Note there is a contact on the reverse side. Ex George Sutherland collection. From: Pingwu Beryl Mine, Mount Little Xuebaoding, Mianyang, Sichuan, China. Dimensions: 4 cm x 6 cm x 9 cm
