Butte, Montana, U.S.A.

An aggregate of several heavily-intergrown Digenite crystals makes up this thumbnail piece. The aggregate is in excellent condition, showing no damage, and shows some good, though incomplete, isometric form. The mineral has a dark gray color and a very dull, almost submetallic luster, and is completely opaque. It is interspersed through a bit of white calcite matrix, and some coppery-red color and brighter metallic luster are visible on the piece. It is affixed inside a plastic thumbnail box with a removable putty.

Dims: 1.6 x 0.9 x 0.7" (4.1 x 2.3 x 1.7 cm)

Leonard Mine, Butte, Silver Bow County, Montana, U.S.A.

This small hand specimen consists of a chunk of massive Digenite. It shows no crystal form whatsoever and almost looks like a piece of furnace slag. However, its density betrays its metallic content and its blue-black color and submetallic luster are characteristic of the specie, as is its locality. There is no host rock present.
