Pyrite octahedrons (excellent) Ken Roberts Coll.

Item Description

Superb and aesthetic pyrite from this less well-known Peru mine. The striking 2.5 cm octahedron dominates this exceptional miniature cluster of mirror-bright, brass-yellow octahedrons. Octahedrons are uncommon from here, as most pyrites are cubes. Complete all-around and essentially pristine, except for the acceptable basal periphery wear. An exceptional and rare style pyrite from the Ken Roberts Collection. These pyrites rank as some of the best from anywhere in the world. This elegant piece has multiple display views. Valued by Ken at $450.
