Calcite (twin) on Quartz with Dolomite (rare locality specimen)

Item Description

This piece is listed as coming from the "Aaka Mine bei Tata" in the "Saghrou Gebirge" = Jbel Saghro of Morocco. I can't find a listing for this locality in any database, so if anybody has a bit more detailed information about where this piece might have been found, please let us know. For reference, the collection catalogue mentions that this discovery took place in 2004. This piece is not what one typically expects to see from Morocco, as it features a gorgeous, lustrous, gemmy, golden, complex twinned crystal of Calcite measuring 4.6 cm across, sitting aesthetically atop prismatic, colorless, gemmy Quartz crystals with little white rhombic Dolomite scattered about. The Calcite is unfortunately cleaved on one end, but it's still an eye-catching and as far as I know, unique example that would make a nice addition to any worldwide Calcite collection or a suite of minerals from Morocco.
From the collection of Kurt Hefendehl (#233 MC), 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 through our various platforms.
