Chalcopyrite - classic, fine twinned crystal
Biersdorf, Daaden, Daaden-Herdorf, Altenkirchen District
Rhineland-Palatinate, Germany
6 x 4.9 x 3.4 CM (cabinet)
price: $1650
Post Tucson 2022

A brilliant golden Chalco crystal (3 CM across) perfectly twinned and perched on contrasting matrix. From the old mining region of Biersdorf (Rhineland-Palatinate, Germany) which is well-known for excellent Chalcopyrites, among the very best known in Germany. Even among the many good pieces from here, this is an incredible standout specimen. We do not have an exact mine name for this piece, but both the Fusseberg and Freidrich-Wilhelm mines are likely candidates. The perfection of the star-like twin is impressive, this is an excellent Chalcopyrite from anyplace. Highly esthetic, lustrous metallic on the front side and with a dark patina on the back, this is in excellent condition with no damage which is rare on this soft, brittle mineral. A superb German classic.
