Description

One of the best historical pieces of skeletal galena (= strickblende/knitted galena) in a sphalerite-wurtzite schalenblende from Kelmis. It comes out of the university of Aachen (Aaken) stock from before the first world war - before 1914!

In this time Kelmis was still German territory.

Perfectly cut and polished, great luster. Much better in nature.
