Thick, heavy formation of solid Copper with a minor amount of attached Calcite. Comes with an old British Museum of Natural History label.

Flat sheet of Copper covered by acicular Chalcotrichite (needle-like form of Cuprite).

Large, double-terminated blue-cap Dravite from a unique 2017 find. This one has so many things going for it, most importantly it's large size and good condition with only one bit of chipping along the termination. It features a dark body grading up to a translucent white zone followed by an intensly blue termination. While the dark zone in the majority of the crystals were opaque, this one is translucent, even despite it's larger size (I put a pen light behind it in one photo to show the translucency). The other end is terminated with a more pyramidal shape and has green overgrowths. There is another small Dravite intergrown in this end.

Cluster of deep blue Azurite crystals with a minor amount of attached Malachite. This is from what is called the Watercourse Pocket of the mine which produced some of the best specimens ever found there. Specimens from this pocket were composed of interlocking, lustrous crystals such as these. Like many from this pocket, it is a floater with small needle-like crystals of Malachite attached. This specimen features a 1.9cm main crystal with smaller intergrown crystals.

Cluster of 4 orange Stilbite crystals on a matrix covered by drusy Quartz. Small Quartz crystals are scattered across the surface of the Stilbite crystals.

Vuggy rock matrix. The vugs are lined with drusy Quartz crystals and two of the vugs contain double-terminated Quartz crystals known as 'Herkimer Diamonds', the largest measuring 1.6cm wide.

Floater cluster of Copper with large, very well formed crystals. This is a replacement of Copper after an Azurite cluster and has unusually well separated, distinct crystals.
