Description

Even though the Saarland was once a very important mining area, nowadays very rarely you can find a mineral specimen from the old mines. This specimen is very good, for what you see from this region. The siderite is lustrous, spotted with tiny chalcopyrite crystals. Contact marks are limited to the sides.
