Two light lavender casts of Topaz after Augelite associated with elongated, transparent Quartz crystals. This was fouond about ten years ago when the great Augelite finds were made. There are two casts present, the largest over 2cm. This is the best of only a few I saw available. They were originally thought to be Fluorite after Augelite, but have been tested and confirmed to be Topaz.

Classic old specimen of translucent blue Chalcedony that has repalced cubic Fluorite. Lustrous undamaged crystals. Comes with an old Julius Bohm label.

Large intergrown Enstatite crystals that have been replaced by green Talc. Complete all around and terminated. These were found in approximately 1900-1910 and this is considered a large specimen. Comes with an old German label.

Rare pseudomorph of Orthoclase after Quartz. Orthoclase hosting the 3cm pseudomorph at one end, mostly the termination of the former Quartz crystal. Collected in the 1970s, this is one of only a small number of specimens known.

Large, relatively flat specimen with the front face covered by crystals of Galena that have replaced Bournonite. Individual crystal reach 1.2cm in size and are undamaged.

Specimen of Realgar and Orpiment that has replaced fossilized coral. Sawcut on front face to show the coral structure.

Glassy, transparent Fluorite cubes to 3cm on edge grown around a cluster of Arsenopyrite crystals. The Fluorite have green and purple color zones. A 3cm Ferberite crystal extends into the upper back of the Fluorite cluster and there are Quartz crystals attached to the top. I found one small edge nick on a side crystal, otherwise undamaged. Bright and showy, better than photos.
