Double-terminated Tourmaline with classic Paprok colors of green with a red termination.  Undamaged with good transparency.

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.

Cluster of Tennantite after Azurite crystals covered by Smithsonite crystals. This is the most aesthetic example of this Tsumeb psuedomorph I have seen, and only one of very few that have the associated Smithsonite. It's a floater crystallized all around with a tall 4cm main crystal rising straight up out of the group. The small black areas are not damage - just areas where the Tennantite is corroded and Smithsonite did not grow. The main crystal is completely covered by Smithsonite on the backside and shows mostly Tennantite on the front side. Comes with a custom Lucite base that says 'Tennanite after Anhydrite", though I have only ever seen these called Tennantite after Azurite.

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