Description

This is my last excellent sample for Strickbblende (knitted Galenite and Sphalerite/Wurtzite) from the classic Schmalgraf Mine, La Calamine, Belgium, famous for such very special specimens.

This stunning, on one side polished slice shows an exremely high luster and a stunning structure. Rarely available in this outstanding quality on the mineral market!

Mined in the early 19th century
