Microcline (''Baveno'' Twins) with ''Chlorite''

Item Description

A showy display specimen of this hard to find material from Poland featuring several very sharp, rather lustrous, prismatic crystals of Microcline measuring up to 3.8 cm, showing excellent "Baveno" twinning habits, which are lightly dusted with moss green "Chlorite" on the surface. The piece is in fairly good condition, but it's a bit rough around the periphery where it was separated from the pocket wall. I don't remember seeing such a robust and three-dimensional piece like this, usually the specimens from this locality are loose single crystals, or only a couple crystals on matrix. This is a really good example of this seldom-seen material, with larger than average twins and that distinctive green hue that really separates from other Feldspars you'll find around the world. Valued $1,250.
From the collection of Kurt Hefendehl (#18 P), 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.
