Large open vug lined with Quartz over Chrysocolla with isolated clusters of dark green Clinoatacamite. At the lower right is a single 4cm Selenite crystal grown over a Clinoatacamite cluster. Uncommon for both overall size and the great isolation of the crystal clusters. These are regarded as the world's best Clinoatacamite specimens. 

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.

Sharp, transparent single Wulfenite crystal from the Rowley Mine.  A small but stunning undamaged gem of a Wulfenite. Great color and luster.
