Colorful thumbnail of this uncommon Copper-Vanadium specie from Arizona. This specie was known as Calcio-Volborthite for many years but is now renamed Tangeite after this was re-described from an older type locale in Kyrgyzstan. Well-formed crystals on contrasting matrix that are especially vivid under the microscope. This mining area close to Monument Valley has several small old workings which were sources as far back as the late 19th century.
The famed old Spinel locality of Amity was one of the first of the Eastern USA Classic locales. The exact original locality may be lost today but the Skarns in the area have yielded some nice Spinels from time to time. This is an older piece with fine octahedral Spinel crystals on a crystalline orange Chondrodite matrix. Ex Hladysz collection, this has sharp form, nice arrangement and excellent luster with no damage. Displays very well from several angles and better in person.
A complete doubly terminated twin Alexandrite (color shifting) Chrysoberyl with textbook form. The crystal is coated on a few faces with a thin layer of Muscovite but the exposed faces are translucent to transparent under strong light. This is a fairly old specimen (originally labelled as locality - Fort Victoria, Rhodesia) from what is now Zimbabwe. This crystal has very good color change from green to red depending the light source. This location did not produce much in the way of gem grade but the specimens were on occasion very well-formed and excellent examples of this remarkable mineral.
A colorful mix of rare minerals that are very well-crystalized. The Metatyuyamunite is in well-defined crystals mostly of yellow hues and the Hummerite (a rare Vanadium specie) is the more orange color. Coffinite is identified as well and there is at least one other specie present as bright green platelike crystals. This piece was in the Ruth and Andy Palmer rare species collection (and later Hladysz) which was used as a research tool by the late Dr. Joe Manderino. This area is the type locale for Hummerite, the name Uravan is formed from the element names Uranium and Vanadium.
Chalcopyrite on Sphalerite

two large, well formed and complete Chalcopyrite crystals perched esthetically on a crystallized Sphalerite matrix. While Chalcopyrite is not a rare mineral, very good crystals like these are very uncommon. These are in perfect undamaged condition reaching 4.3 CM and having a fine brassy patina, these are classic textbook crystals. On several faces are a sprinkle of tiny bright golden Pyrite crystals that add a nice sparkle. From Huaron Mining district of Peru this specimen is more than 20 years old, a fine heavy Sulfide piece that looks great from most any angle.
Nekoite is a rather rare mineral in good crystals and the best known come from the Iron Cap Mine. Not often seen in collections or in sizable specimens, this very rich piece of both Johannsenite and Nekoite. Both are well-crystallized and plentiful on many surfaces of this complex specimen. As a bonus there are several gemmy crystals of Manganaxinite hiding in the mix. Nekoit has a resemblance to Okenite which at one time it was mistaken for. The name was created by writing Oken backwards and adding the ite. Best appreciated with good magnification, the crystals of each specie are well-defined and show several habits.
Excellent blue-green color Smithsonite with a wet look, shimmering luster. The botryoidal surface is host to several "eyes" which are holes with a white rim which adds an nice contrast. The remarkable deposit at Choix is not producing at this time, but when it was active the Smithsonites were plentiful on the market. Many colors and forms were found making this a world class locale, often compared with the Kelly Mine in the USA. This piece has the eyes that were famed at the Kelly Mine and the color is comparable too, but as a Mexican specimen this is less costly and a great value for a pretty blue-green cabinet sized Smithsonite..

An unusual habit from this famed Canadian locale, a spherical rosette of small bladed crystals hosts a cluster of larger twinned Selenites. The overall effect is very esthetic and looks fine from any angle. The crystals are a golden to orange-yellow color except at the terminations which are a milky white. In fine condition, we have handled a lot of Selenite from this locale but this piece is quite different in style. As is usual for Selenite from the Red River this is strongly fluorescent.
