Chalcopyrite (twins)

Item Description

A classic specimen of these now hard to find Chalcopyrite specimens from the San Martín Mine in Mexico featuring many very sharp, highly lustrous (splendent), rich brassy colored twinned crystals measuring up to 1.0 cm, which are associated with thin prismatic crystals of white Calcite, along with colorless, gemmy Quartz crystals, and minor black Sphalerite on matrix. Virtually all of the Chalcopyrite crystals are undamaged, and they look beautiful up close with their multi-stepped faces and distinct "heart"-shaped or "butterfly"-shaped twins. Beautiful material, some of the best crystallized Chalcopyrite from not just any mine in Mexico, but North America.
From the collection of Kurt Hefendehl (#294 MX), 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 over the next two to three years through our various platforms.
