Dark green crystals of Kolwezite and/or Malachite that has pseudomorphed after Barite (?) on Cobaltian Calcite. The pseudomorphs form a cluster about 4cm wide in a vug. The Cobaltian Calcite is brown with an later generation of vivid pink. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species. private_notes

A 4cm wide cluster of dark green Malachite on rhombs of pink Cobaltoan Calcite (or possibly Cobaltoan Dolomite) creating a stunning mixture of colors and forms. A beautiful and colorful combination specimen.

Dark olive green Kolwezite atop rhombs of pink Cobaltoan Calcite (or possibly Cobaltoan Dolomite) creating a stunning mixture of colors and forms. There are a few clusters of an earlier generation of botryoidal Kolwezite but the majority is a second generation of slightly lighter green Kolwezite in clusters of angular crystals, possibly pseudomorphs. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species. A beautiful large display piece and combination specimen of two desireable species together.

Long, shimmering stalactites of Malachite on a matrix of solid botryoidal Malachite. Wild looking Congo classic.

Glassy white Datolite crystals on matrix. Found by a friend while prospecting in this area known for Jadeite and Rosenhahnite crystals. These were found in a single boulder that was excavated during construction work on Highway 101. This boulder produced what are considered Californias's best Datolite. Individual crystals on this specimen reach 7mm in size and are translucent to transparent. Superb piece for a California suite of minerals.

Smokey Quartz cluster on Microcline with a terminated green Tourmaline crystal projecting out near the base of the Quartz. The Quartz have an unusual and intersting 'spotted' appearance due to radiation halos from Uranomicrolite. There are also Tourmaline included within the Quartz. Ex. Cal Graeber collection with his number on back.  Cal used to work with Bill Larson when he owned the mine and is a true San diego county expert.  The fact that he kept this specimen in his collection speaks for it's rarity and quality.

Large, dark green single Tourmaline crystal from recent production at this famous mine in Zimbabwe. Tourmaline has been very rare from this mine historically, which has primarily targeted blue Topaz. Most Tourmaline found here occur as small pencil-like crystals and this fat, somewhat tabular crystal in an anomaly. Though dark, it is transparent facet grade throughout with a more greenish brown at the upper third and a bright pure green in the lower two thirds. There is a bit of edge chipping along the sides, it's complete all around, and has a perfect termination. Weighs a hefty 153 grams.

Gem Tourmaline crystal recently mined from the famous St. Anne's Mine in the Karoi district of Zimbabwe. Fully terminated, complete, and nearly undamaged with just slight edge chipping. It's transparent top to bottom with a good medium green color over most of the crystal with a darker green (though still transparent) termination. The termination is multi-faceted and complex. Excellent quality Tourmaline.

Large, deep red complete Zircon crystal from Tanzania, much larger than typical for this locality. It has a steep pyramidal termination and is nicely transparent when backlit.
