Siderite (''ball'') with Calcite (ex Kurt Hefendehl Collection)

Item Description

A beautiful spherical group of tan colored Siderite from the Nikolaevskiy Mine in Dalnegorsk, Russia. The "ball" is complete on the top, and plays hosts to many small compressed silvery colored trigonal crystals of Calcite, and when you flip the piece over, you can see it's partially hollow underneath and filled in with many more Calcites, along with an iridescent metallic crystal of Pyrite. The piece is complete all around and displays well as you can see from the photos. A really good example of these attractive and unusual Siderites from this prolific locale. From the collection of Kurt Hefendehl, 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.
