Description

A really stunning, very glossy piece of skeletal galena in a sphalerite-wurtzite schalenblende from the Schmalgraf mine in Kelmis. It was found before the first world war - before 1914! In this time Kelmis was still German territory.

Perfect polish and shine. An outstanding specimen. Very 'artistic' 'design'. The luster is absolutely great in nature. Unfortunately we can only reproduce a 'shade' of the quality this specimen has.
