Fluorite (colorless) on Calcite

Item Description

An unusual Fluorite specimen, labeled as coming from "Dongbo" = Dongpo, Hunan, China. The piece features a very sharp, rather lustrous, gemmy cube of Fluorite measuring 2.7 cm on edge, with a few smaller Fluorites associated with attractive smoky-golden colored, vitreous compressed trigonal Calcite crystals, on matrix. The Fluorite crystals are notably colorless, a sign of chemical purity, and honestly a fairly rare occurrence for the species in nature. The main Fluorite is undamaged, and the only roughness is around the periphery where the piece was separated from the pocket wall. It displays wonderfully on its own without the aid of a base or clay, due to a saw mark on the bottom. I have to say that both the Fluorite and the Calcite exhibit colors that I can't remember seeing from anywhere in the Dongpo Ore Field, but China has produced so many isolated discoveries of interesting and unique minerals, that I'm not surprised.
From the collection of Kurt Hefendehl (#788 C), 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.
