Bismuth with Skutterudite and Erythrite (ex Kay Robertson Collection)

Item Description

A cool piece of ore from the famous locality at Jachymov (Joachimstal) featuring silvery Native Bismuth associated with grey Skutterudite and coated by a soft pink layer of Erythrite. These are rare from any Czech locality. The Bismuth shows a tiny bit of crystalline form when viewed up close. Ex Kay Robertson Collection (#11217).
