Prehnite (classic locality)

Item Description

The Prospect Quarry in New South Wales, Australia is a famous locality for Prehnite specimens, and the entry on mindat.org states that, "The quarry is famous for its world class Prehnite". I've seen specimens in wide range of colors from orange and yellow to beautiful green and blue-green examples. This piece is a wonderful big showy cabinet filled with gemmy/translucent, attractive blue-green colored semi-spherical aggregates covering the entire display side of the specimen. Minor attached matrix can be seen on the reverse side of the piece. Minor roughness can be seen in a few spots, but overall the piece is in great shape, and it's a notably impressive and eye-catching example of this now hard to find material since the quarry closed for good in 2010 (it originally opened in 1820!).
From the collection of Kurt Hefendehl (#146 AU), 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 through our various platforms.
