Description
A well-defined, 1 cm measuring sharp Bournonite crystal with attractive tarnish on an elongated siderite/calcite matrix. Yes, admittedly there are these much bigger Bournonite crystals coming out of China, however, nothing beats an old European classic like this one. Considering that the Georg Mine, an iron mine, was abandoned in the mid 1960s, this pristine specimen is much older. Come and get it, it´s rare and good example or the locality.
