Item Description

This is honestly the only specimen we've seen of its kind from Pakistan. While there are many localities where fine crystallized examples of Feldspar have been found in Pakistan, they are typically white in color. Occasionally we might see something colorful like the rare purple Albites, but this piece is distinctly unique in its hue. The piece was simply labeled as "Feldspar" in Kurt's collection catalogue, but I'm willing to bet it's Microcline. With that said, it's one of the most unexpected colors I've seen for the material as it can best be described as a pastel "seafoam" hue, and it's visibly different than say a pale colored Amazonite. Additionally, the form / arrangement of the piece is odd for Feldspar, as it's a tightly intergrown cluster of crystals, flaring in a multitude of directions, with no matrix, and only a tiny bit of associated Muscovite "rosettes". It's hard to convey the quality in the video, but these Feldspar crystals are not only sharp and very well-formed, but they highly lustrous, with a reflective "wet" luster on the surface. Additionally, the crystals pass light when backlit, showing a gentle internal translucency that you wouldn't normally expect from most Feldspars. The majority of the crystals are in good condition, but there are some contacted areas, so the piece is not 100% pristine, but the damage is more than forgivable in my mind as the color is so unique. The largest crystal measures 3.0 cm long. If you collect Feldspars, pegmatite minerals or specimens from Pakistan, do NOT miss out on this chance to get your hands on something that is incredibly rare in terms of the strange and desirable color. We don't have another like it to offer.
From the collection of Kurt Hefendehl (#257 AP), 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 for the coming months/years through our various platforms.
