Large, intergrown rosettes of Azurite crystals from early production at the Shilu Mine in China. This is an old Al Ordway specimen and comes with his old label. Al was one of most famous California field collectors and a really fine mineral dealer. A complete all around undamaged floater with no points of attachment. Most of this find were singles with subpar luster and some damage. This is a very 3-dimensional piece composed of multiple intergrown rosettes. Better in person!

'The Sand Dune'...Lustrous orange Wulfenite crystals on matrix from Los Lamentos, Mexico. The Wulfenite have the best color for the locality and good luster and are nearly pristine with just minor edge chipping on some. The matrix is artistic, aesthetic, and unique. Drusy Calcite is studded with Wulfenite of the highest quality and color for the locality. A really neat feature is the wavy 'sand dune' like appearance of one side. Comes with a custom Lucite display stand.

Shiny metallic crystals of Bournonite from the Viboras Mine in Bolivia. The crystals are pristine and have bright silvery coloration, much more so than photos indicate - even better in person! The large cluster on top is 4.5cm wide and the intergrown pair of crystals below reach 3cm in size.  Comes with a custom Lucite display stand.

Two interconnected crystals of Topaz bisected by a single Tourmaline crystal with a touch of Albite at the base. Both of the Topaz crystals are glassy and translucent to transparent. The Tourmaline is Elbaite due to the presence of a thin green zone at the termination and provides a stark contrast between the two golden Topaz crystals. All the crystals are pristine and come together to form an aesthetic display piece. Comes mounted on a Lucite stand.

Bold and dramatic bow-tie cluster of Arsenopyrite crystals from the Panasqueira Mines in Portugal. An exceptional example of a fairly common mineral, the cluster is complete all around and undamaged with bright, silvery metallic luster. Comes with a Lucite display stand. Ex. George Holloway specimen.

Glassy apple-green crystals of Apophyllite in an absurdly aesthetic bow-tie cluster.  This specimen is the epitome of natural art.  The cluster of Apophyllite crystals are perched dramatically atop peach colored Stilbite crystals. In the world of Apophyllite specimens, one in thousand is a bow-tie formation. Of those few, 99 percent have damage of some kind. Do the math, this is a special and rare specimen. Comes with a custom Lucite display stand.

One of a kind specimen composed of casts of scalenohedral Calcite crystals that are coated with Cuprian Adamite, Rosasite, Malachite, and colorless Smithsonite. This specimen has the desired qualities of being aesthetic, colorful, mineralogically interesting, and rare. There are a couple old collection numbers affixed to the bottom. Rare and unusual!!!

Rare specimen of Goethite after scalenohedral Calcite crystals that are coated with radial sprays of fibrous Olivenite and bright green Conichalcite. There are additional minerals present, and the old label notes the possible presence of Attikaite. This specimen has the desired qualities of being aesthetic, colorful, mineralogically interesting, and rare. There are a couple old collection numbers affixed to the bottom. Unique and unusual!!!

Classic lustrous brown Pyromorphite crystals on a Galena rich matrix from Bad Ems, Germany. Ex. John Sinkankas specimen and has his collection number ('JS PYM 2) painted on the bottom. This specimen is also illustrated on page 421 of Sinkankas' famous book 'Mineralogy for Amateurs'. John Sinkankas was a legend in the field of mineralogy, this is your opportunity to own a piece of history along with an excellent, classic mineral specimen.  Comes with a custom Lucite stand.

Complete crystal group of the rare mineral Volkovskite from the Boulby Mine in England. This is one of only two known terminated crystal groups collected from a single find made deep in a section of the mine that extends out under the Altlantic ocean. The Volkovskite was found during normal mining operations for potash when the mine machinery stalled when it encountered a mass of the much harder Volkovskite. Because Volkovskite damages mine machinery, the area where it was found is now avoided and it is unclear if anymore will be recovered. This recent find of Volkovskite has set the world standard for the species and this specimen is one of the best. The specimen has crystallized surfaces all around - most were just cleavages (the cleavage structure can be seen on the bottom of this specimen, last photo).

Stunning and important Benitoite/Neptunite specimen from the Gem Mine in California. This specimen is composed of a flat schist matrix partially covered by white Natrolite hosting two large Benitoite, Neptunite, and a single Joaquinite crystal. The largest Benitoite is 3cm wide (and the second crystal is not much smaller). The truely great Gem Mine specimens are composed of Benitoite, Neptunite, and Joaquinite on white Natrolite - this specimen checks all the boxes. This visually appealling specimen was in the personal collection of the late California mineral dealer Al McGuinness. Al was an active dealer in California during the heyday of Benitoite mining and had the opportunity to select the best. The fact that he kept this particular specimen speaks to it's exceptional quality and visual appeal. 

Large, lustrous Dioptase crystals on white Calcite from Tsumeb, Namibia. The Dioptase crystals reach 2.3cm in size and are translucent to transparent.  Although Dioptase specimens are found at other worldwide localities, those from Tsumeb, especially on white Calcite crystals, are considered the world's best and let's face it, Tsumeb is the magic word to most connoisseurs of fine mineral specimens. The Dioptase crystals show a unique fine etching that extends into the gemmy crystals. Dioptase is notoriously difficult to photograph and this is MUCH better in person. At 12cm wide, this is a large and significant Tsumeb Dioptase.

Icey-blue specimen of gem quality Aquamarine from Brazil. This has been naturally etched in the pegmatite yielding this remarkably formed specimen.  This Aquamarine is like frozen ice that never melts. This specimen is pristine with hundreds of glassy faces on all sides.

Quartz crystals (smokey and Amethyst) replacing a long Anhydrite crystal from Brazil. This rare pseudomorph has alot of character. The shape of the former Anhydrite with Quartz crystals along the edges reminds me of a chain saw blade. Translucent to transparent, pristine with an abundance of life, a truely unique specimen. Comes with an old Ken Roberts label.  Ken is a mineral dealer noted for his high level of taste and aesthetics.

Colorful combination specimen of Inesite and associated minerals from the Daye Mine in China. Bright red rosettes of Inesite to 2cm in diameter are attached to clear Quartz crystals (most Inesite has a brown component that this one is lacking). Associated minerals include Pyrite and clear, tabular Apophyllite. Comes with a custom Lucite display stand.
