Several crystals combine to form this really beautiful cluster of solid chalcopyrite. It is nearly a floater all around, with just some minor contact and a few small bits of damage only. It looks like a solid mass of chalcopyrite topped by two lustrous brassy yellow crystals, to 3 cm in length, although those crystals help compose the actual matrix itself as well. This is a very choice chalcopyrite from China, in quality resembling the best of Peruvian material. It is robust and has excellent color. The detail is very complex with small striations throughout. Collected 2005-12-10 from a prominent and carefully assembled collection of Jiangxi minerals with precise localities.
