Choice oldtimer specimen featuring a solid tabular (possibly twinned?) crystal of bournonite, featuring a slight tarnish, proudly cropping out of crystalline blades of hazel siderite.

The specimen is one of the best I have ever obtained, and it came from a Swiss collection. It dates back to pre-1950s. Rare material to obtain nowadays.
