Glassy, flower-like cluster of Quartz crystals on a matrix covered by small Calcite crystals. Highly aesthetic, undamaged specimen. Ex. Chuck Trantham collection.

Two connected crystals of Malachite after Azurite pseudomorphs. Rich green with a velvety surface luster. Comes with an old Al McGuinness label.

Double-terminated transparent Calcite crystals with sharp phantoms caused by Hematite inclusions. There are additional smaller crystals sticking out at right angles from the main crystal. Undamaged. Ex. Bob Reynolds collection.

Deep blue crystals of Clinoclase on matrix from the now defunct Majuba Hill Mine. The area of crystals is 4cm wide. An excellent example for the locality and of the species.

Deep blue crystals of Clinoclase over green Cornubite from the now defunct Majuba Hill Mine. Both the front and back have great crystals.

Beautiful large specimen of Dioptase on drusy Quartz over Chrysocolla and Malachite. This looks like something out of Africa rather than the USA, but it's old Arizona material with large isolated Dioptase crystals to 7mm in size. A big and colorful Arizona classic that will add pop to a mineral case.

Large rhombic Calcite crystals comepletely coated by thick, large crystals of dark green Mottramite intergrown with a second generation of lenitcular Calcite crystals. Clean and undamaged, an excellent Mottramite specimen.

Bladed groups of long Azurite crystals. Well crystallized all around and pristine. Some areas show etching.

Spheres of blue Rosasite atop spikey crystals of green Aurichalcite.

Unusual finger-like formations of pink Cobaltoan Calcite in a Quartz crystal lined vug. The individual crystal aggregates reach 8mm tall. There are so many neat and unusual minerals found in this part of the world and this certainly is one of them.

Cubic Silver crystals on matrix that have been exposed from white Calcite. Cubic Silver crystals are uncommon and these are superbly formed, sharp cubes to about 2mm in size. The crystals are present on a Safflorite matrix around some remaining etched Calcite.

Deep blue crystals of Clinoclase over green Cornubite from the now defunct Majuba Hill Mine. Both the front and back and 1 side have great crystals.

Cluster of clear Quartz crystals with Dioptase. The main Dioptase is 1.3cm long, double-terminated, with both ends extending out opposite sides of the Quartz cluster. Old, rare specimen. Dioptase, when included in Quartz crystals, make rare and valuable specimens.

Bright metallic Galena cubes to 2.5cm on a silicified limestone matrix with red 'Ruby-Jack' Sphalerite crystals, Dolomite, and Calcite crystals from Treece, Kansas. The Galena are present on one side, but the specimen detached in the pocket and the Sphalerite and Calcite are present on all sides, making this a floater.

Bright yellow crystals of Sulfur attached and fully included within transparent Gypsum var. Selenite. Sulfur inclusions in Selenite are uncommon and this is an excellent example. See the current issue of Mineralogical Record for an article on this locality.
