Massive Calcite, Prehnite and Copper with a crystallized vug of the same species. There is a large 4cm Copper crystal in the vug as well as a mass of Prehnite that rises up and contains 2 well formed Copper crystals to 2.5cm wide.

Classic Almandine specimen from Zillertal featuring two dark reddish-brown Almandine crystals in a schist matrix. The well-formed dodecahedral crystals reach 3.3cm in size.

Classic Italian Almandine specimen from Seeber valley featuring five dark reddish-brown Almandine crystals in a schist matrix. The well-formed dodecahedral crystals reach 4.7cm in size.

Olive-green to brown Microlite crystals on Orthoclase crystals that are coated by Lepidolite. There are 10 octahedral Microlites crystals to 8mm in size present on the specimen. A rare, hard to find specimen.

Purple and yellow Fluorite crystal with attached red Sphalerite crystals from the famous Fluorite region in Hardin Co., Illinois. The Fluorite is rectangular and complete all round with cubic purple Fluorite over a yellow core. Translucent with color zoning.

Thick, transparent colorless Cerussite crystals, shocking in size and quality for the locality. This is from a recent find and look more like something you would see from Tsumeb than any I've ever seen from the Ojuela Mine. The specimen is composed of a large single crystal with a smaller V-twin attached. Unfortunately while photographing, the small V-twin detached from the main crystal and I had to therefore reattach it (the smaller crystal fits perfectly into an angular groove on the larger crystal like a puzzle piece).

Large, complete single Azurite crystal from the Milpillas Mine. This is a floater well crystallized all around. There is some minor chipping present, but overall it's in good condition. Nice to find a complete single crystal like this. Both sides shown in photos.

Lustrous Amethyst Quartz crystals known as 'Cactus Quartz' from South Africa. There are two generations of growth. The first generation has large Amethyst crystals measuring about 1.4cm thick, with a second generation of smaller crystals attached to the prism faces on the larger crystals. Undamaged.

Crystals of translucent, lenticular Dolomite and tan colored Siderite all sprinkled with metallic crystals of Pyrrhotite. Ex. John Betts personal collection.

Large rock matrix covered by tiny clear Calcite crystals which are in turn sprinkled with small green Malachite spheres and starburst clusters of yellow Mimetite. Good coverage on both sides.

Complete 'citrus' orange Spessartine crystal from old finds in Tanzania. These were mostly found as partial or damaged crystals with complete crystals such as this much less common. Excellent form with a few small edge chips and surface pits but no significant damage. Translucent with great color, there are some darker black included areas but also areas of superb gem transparenct. Weighs 37.30 grams.

Intergrown cluster of tabular blue Alkali Beryl crystals, Tourmaline, and Mica. The Beryl crystals reach 1.3cm in size with glassy luster on the thin edges. The colorful Tourmaline crystals show light etching. Well crystallized all around. Note that these were once thought to be the Cesium rich species Vorobyevite but analyses did not show Cesium and this name has since been discredited.

Three crystals of translucent to transparent Apatite crystals in a vug with Quartz crystals. The crystals have good purple color with the main Apatite crystal 1cm in size. Sawcut on base and one side. 

Cluster of translucent Azurite crystals on starkly contrasting white matrix from the Volborthite pocket of the Milpillas Mine. The Azurite from this area of the mine are known for their distinctive tabular crystals that occur on a white matrix. The crystals on this specimen reach 2cm in size and are in pristine condition. Highly translucent with backlighting with a blue glow showing on the white matrix below.

Inky, translucent blue Fluorite crystals partially coating Quartz crystals. This is a superb example from this occurrence, one of the best I've seen. Pristine and undamaged all around. Ex. Len Pisciotta collection and comes with an old Andy Seibel label.
