Large intergrown Enstatite crystals that have been replaced by green Talc.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.

Purple Fluorite cubes to 3cm on edge intergrown with Arsenopyrite and Muscovite crystals, all atop a Quartz crystal. Good all around and undamaged.

Water clear light green Fluorite cubes on matrix. Central main isolated cube is 2cm on the diagonal. Some of the smaller crystals are so clear you can't see them until you reflect light off their faces. This is the best quality from this find that I could find. Complete all around and undamaged. Better than photos.

Transparent purple/blue Fluorite cubes on a Quartz crystal covered matrix. Exceptionally bright crystals! It really pops when compared to others. Glossy, wet-looking luster. There are a couple tiny, trivial nicks that you have to search for, otherwise undamaged. This one is really nice and way better than photos.
