Sharp crystals of blue Azurite intermixed with green crystals of Malachite after Azurite pseudomorphs on a light matrix with additional yellow/green mineralization. Undamaged crystals with pseudomorphs that reach 2.2cm, some of which are double-terminated.

Achtaragdite is a rare pseudomorph of a hydrogrossular-chlorite-carbonate mineral after what is believed to be Helvite. This is a little understood psuedo likely found many decades ago at the type locality for Grossular garnet in Siberia. It is a fine example with a well formed tetrahedron of the form of the former Helvite crystal. 

Glassy, colorless/white orthorhombic crystals of vuagnatite, a rare silicate mineral, on matrix. Collected by Chuck Trantham in 1982 and valued at that time at $100.

Vug completely filled by radial masses of light blue Hemimorphite crystals. Ex. Chuck Trantham collection. Undamaged.

Scalenohedral pink Cobaltian Calcite crystals covering the front face associated with rounded masses of Kolwezite. Ex. Cliff Krueger, Chuck Trantham collections.

Thick, lustrous black Neptunite crystals on a flat matrix of Natrolite over schist. This is an old Steve Perry specimen that I purchased from Steve about 20 years ago and have kept in my collection ever since. All the crystals are terminated and undamaged, the main crystal is 2.5cm long. There are small brown Joaquinite crystals on the Natrolite.

Single clear Quartz crystal heavily included by silvery crystals of a mixture of galena, pyrite, chalcopyrite, and tetrahedrite (Ag-rich 'Freibergite'). Ex. Chuck Trantham collection. Acquired by Chuck in 1980 from Al McGuinness
