Skutterudite (Var: Smaltite), Bismuth
Small Cabinet, 5.4 x 3.6 x 3.6 cm
Schneeberg District, Erzgebirge, Saxony, Germany
A solid mass of very heavy, metallic ore is host for sharp crystals of smaltite, the cobalt-rich variety of skutterudite. Classic old material. This is a fine piece with crystals to 4 mm including a sharp cube, atop. I have chosen not to clean this piece of its accumulated patina. Note the attractive wavy growths of native bismuth, on which the crystals sit. Ex. John White Collection.
