Azurite partially altered to Malchite, with the Malachite forming fine 'bulls-eye' patterns. The Azurite is sharply formed with lustrous faces. The back is a large 10cm partial crystal and there are 2 terminated Azurite crystals attached to the front, the best is 5cm tall and grown out away from the largest crystal.

Copper crystal cluster with a deep, rich patina. Good on both sides and undamaged.

Cluster of double-terminated Quartz crystals known as 'Herkimer Diamonds'. Bright and glassy crystals that are complete and undamaged all around.

Snow-white Barite blades, with some that are amber colored, over a matrix coated by drusy Sphalerite.This is out of an old collection built in the 60s and 70s and is surprisingly clean and undamaged, good from both sides. 

Large cubes of lustrous Galena crystals, to 5.2cm on the diagonal, on matrix associated with Chalcopyrite and Calcite crystals. Such specimens with good large crystals on matrix are no longer common.

Elongated Pyrite groups that have replaced a previous mineral, possibly Calcite, on a matrix covered by Sphalerite. The base of one of the Pyrite crystal groups is visible and whatever was there before is all gone now - nothing but solid Pyrite. Bright, shiny luster and undamaged.

Well formed large Ferberite crystals associated wtih transparent Quartz crystals. There are also small purple Fluorite crystals, Muscovite, and Arsenopyrite present.
