Cassiterite and Arsenopyrite on Quartz
Viloco Mine, Loayza Province, La Paz, Bolivia
11.9 x 7.2 x 6.8 cm (4.69 x 2.83 x 2.68 in)

A strong Viloco combination with well-formed Cassiterite crystals set on a bright Quartz matrix. The Cassiterite shows a deep, reflective luster and sits prominently across the top of the piece. Arsenopyrite is distributed across the specimen, adding metallic contrast against the Quartz. The Quartz points give the piece structure and keep the display clean. A balanced and top quality example from this classic locality.

From the collection of Bruce Carter [BC1503].
