Hambergite (excellent crystal) with Tourmaline on Albite

Item Description

Hambergite is not typically seen in well-crystallized examples from most localities around the world, but there are a few places that have produced some superb examples in recent memory. This particular specimen comes from Stak Nala, which is best-known for producing the most iconic Tourmalines from any Pakistani locality. With that said, Hambergite is exceptionally rare from Stak Nala, and this particular piece is one of the best examples we've ever seen from the locality. This wonderful small cabinet display specimen features a fine quality, large, rather sharp, highly lustrous, pearly white bladed crystal of Hambergite measuring a whopping 4.2 cm, sitting atop beige blades of Albite (var: Cleavelandite) matrix. A smaller secondary Hambergite can be seen on flaring off the big crystal for a nice touch. If you flip the piece over, you can see a single crystal of multi-color Tourmaline, showing green, golden, black and colorless hues. Hambergite is a rare beryllium borate species that occurs in pegmatites, but you rarely see showy matrix specimens like this from Pakistan or any other locality. If you collect Pakistani minerals, or gem crystals, don't miss out on this great rarity! Valued $3,000.
From the collection of Kurt Hefendehl (#238 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.
