Brochantite (uncommon from Tsumeb)

Item Description

A fairly hard to find specimen of Brochantite from Tsumeb featuring deep emerald green "rosettes" of thin bladed crystals measuring up to 1.1 cm on matrix. The crystals have good luster, not just for Tsumeb but the species in general. With strong backlighting, you can see small flashes of electric color coming through the crystals. The front/display side of the piece is in great shape, with very minor imperfections. If you collect Tsumeb specimens, this is something that is rarely seen on the market, and this piece is a good display quality example from this historic and prolific mine.
From the collection of Kurt Hefendehl (#33 T), a well-known German collector all over Europe with worldwide contacts to dealers and collectors. He started collecting seriously at the age of 14 and his great and varied worldwide collection reached over 6000 pieces. He was very active mineralogically until shortly before his passing in 2020 at the age of 82. Considering his collection had a large number of pieces, it still had an unusually high standard of quality from most worldwide localities. He particularly specialized in all classics as well as minerals of the Black Forest, where he spent much time collecting. His Black Forest and German subcollections went to his good friend Wolfgang Wendel. We at The Arkenstone have the privilege of offering the remainder of this great worldwide collection through our various platforms.
