The Worldwide Collection of Kurt Hefendehl

This week we are pleased to offer a selection of classic specimens from the diverse and historic collection of one of the great mineral collectors of Germany from the last nearly 70 years. Kurt Hefendehl was a well-known German collector in the mineral world 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. 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. Stay tuned for more, and in the meantime here is a selection through the middle of the collection, specializing in classics of the 1970s-1990s.
