Cuprite with Miersite and Marshite
Rubtsovsky Mine, Rubtsovshy District
Altaiskii Krai, Russia
4.3 x 3.7 x 2. CM (miniature)
price: $875
Early summer 2021

This is mostly a fine Cuprite specimen with a main octahedron over 3 CM across, which is very sharp and defined. There are several other smaller crystals and between them are some excellent small crystals of Miersite that are bright yellow, gemmy and well-formed. The Marshite is smaller and less distinct but still a nice addition. From the great find at Rubtsovskly Mine in 2010, these were instant classics when found. The Cuprite is especially lustrous and has geometric growth structures well displayed on the larger faces. Aside from the unavoidable broken area where this was removed, the specimen is perfect, the main crystals are in undamaged condition and are in textbook forms.
