Description

A very interesting and nice pseudomalachite old timer specimen from the Siberia locker at Krantz, Bonn. The accompanying simple hand written label states Phosphorochalcit (old german synonym for pseudomalachite) from Siberia so this is most probably a Nizhnii tagil specimen.

Green spherical aggregates of this rarer copper secondary mineral on quartz crystals, all on altered matrix.
