Item Description

The Chalcopyrites from this ancient iron / copper mine are some of the best examples of the species from any German locality, and beloved by European collectors. It should be noted that according to, this mine was first mentioned in 1712 and closed in 1965. This showy and fine quality small cabinet specimen is filled with excellent, tightly intergrown, sharp, lustrous, lightly iridescent, metallic, brassy sphenoids on matrix, creating an eye-catching specimen from this noted locale. The largest crystal measures about 9 mm, though it's difficult to discern individual crystals as they are intergrown in a way that makes two crystals look like one. There are some crystal that appear to be twinned as well, but they could simply be intergrown at an angle that makes them appear to be twinned. Minor nicks/dings are present, but overall the piece is in good condition and looks great in person. Valued $950.
From the collection of Kurt Hefendehl (#307 D), 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 for the foreseeable future through our various platforms.
