Bournonite cogwheels (2012 find - superb)

Item Description

Massive, stout intergrown bournonite crystals form a dramatic and superb small cabinet from Bolivia. The striking splendent metallic-gray crystals have fantastic dense "cogwheel" faces, characteristic of this classic, desirable species. The stunning large crystal is 4.3 x 2.5 x 1.9 cm. There are even more sharp cogwheels on the back, as a bonus. This outstanding, rich specimen of solid bournonite is from a small 2012 find. Fairly valued at $2000-2500 for large crystal size, high quality and richness. RARE Viboras Mine bournonite in this quality.
