Ettringite

Item Description

It is not common to find well-terminated crystals of Ettringite on matrix for sale, and they have risen in demand since there is little material available these days. This specimen is from the find in the 1990s, and features several well-formed, sharp, euhedral, lustrous, translucent, prismatic, rich yellow colored hexagonal crystals measuring up to 2.0, aesthetically sitting on matrix. The largest crystal is doubly-terminated, and you can see that the terminations of the crystals have more of a golden-brown hue (possibly transitioning to Sturmanite?). Most of the crystals are undamaged, but there are some contacted areas near the eges. A showy and good quality representation of these classic Ettringites from the N'Chwaning Mines. Priced at $1,450 in the inventory. From the collection of Kurt Hefendehl (#21 SA), 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. WWe at The Arkenstone have the privilege of offering the remainder of this great worldwide collection over the coming months and years through our various platforms.
