Pink rhodochrosite with the dominant crystal 6cm wide and perfectly centered atop the specimen. The Rhodochrosite formed as a replacement after Calcite. The specimen has areas of coverage by drusy Quartz and has associated Pyrite.

Two large Azurite crystals on a Dolomite matrix. Largest crystal is 3cm. Both are well terminated. There are small reticulated Cerussites on the Dolomite. I bought this about 15 years ago in Tucson and have held it in my collection since then.

Highly aesthetic specimen of a large single crystal of Malachite with attached octahedra of Cuprite. The Malachite has spherical indentations on the front and backside with a broad, flat termination. The locality is believed to be Ongonja, but it is possible it could be Katanga. Undamaged.

Glassy and gemmy etched Aquamarine crystal. Natural processes in the pegmatite have partially dissolved the crystal leaving this fully crystallized, undamaged gem with oustanding form.

Two larger velvety crystals of green Malchite after Azurite crystals on matrix with blue Azurite crystals.  The Azurite crystals are located both on the matrix and on the pseudomorphs. Fine and undamaged, an excellent Ajo specimen.

Single Tourmaline crystal that grades up from medium green to clear to dark green at the termination. Unusual color zoning. Undamaged, with gem zones.
