Description

Miniature consisting of siderite matrix with a couple small vugs filled with submillimetric sparkling metallic bournonite crystals. The habitus of the bournonite is rather lamellar and with well defined faces and not the typical cogwheels, which reminds of the ones from the more famous Grube Georg, Germany. The quality of the crystals is very good, with good luster, and it is better appreciated with a higher magnification.

A very unusual locality, sporadically seen on the market!
