Vivianite

Item Description

An old and hard to find Vivianite specimen from Ronneburg featuring broad, bladed crystals which are dark in color (due to decades of oxidation) measuring up to 3.4 cm on minor matrix. With strong backlighting, some of the crystals show light yellow to greenish hues, but we couldn't get a photo that showed it off properly unfortunately. The piece is not pristine, there are some broken crystals, but it's still big and showy, and the crystals are bigger than the few I've seen from Ronneburg over the years.
From the collection of Kurt Hefendehl (#192 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.
