Galena on Sphalerite
stock #8.1-443
Krushev Dol Mine, Madan, Rhodope Mts.
Smolyan Oblast, Bulgaria
8.4 x 6.9 CM (cabinet)
price: $250


A sizable (4.4 CM) galena sits in a sea of lusterous Sphalerites. Clean and esthetic, the Galena has some hoppered areas and elaborate growth phase lines. Nice contrast and no damage on the display side.
Pink Fluorite
stock #8.1-444
Chumar Bakhoor, Hunza Valley
Gilgit, Northern Areas, Pakistan
5.1 x 4.9 CM (miniature)
price: $480


A single pink octahedron with frosted faces and very good transparency. The crystal is contacted on the back and base and has some adhering muscovite. The display side however presents well with sharp faces, clean edges and good light pink color. A good value for a crystal of this size.
Fluorite on Dolomite with Chalcopyrite
stock #8.1-445
Naica Mine. Naica, Municipio de Saucillo
Chihuahua, Mexico
6.4 x 5.6 CM (small cabinet/ large miniature)
price: $250


An older piece (60s vintage) from the John Marshall collection, this is distinctly different from more recent materials from Naica. Clear, transparent Fluorites are well placed on a contrasting matrix. The crystals are undamaged, bright, gemmy and have slightly curved faces. Displays very well, this will be a great addition to any Fluorite collection.
Beryl V Aquamarine with Albite on Muscovite
stock #8.1-064
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
7.1 x 5.4 CM (cabinet)
price: $350


A gemmy 4 CM aqua in perfect condition is penetrating a 4.8 CM albite crystal sitting on Muscovite. From the now famous Mt Xuebaoding area, this is a fine combo piece. Unusual relationship is prominently displayed in a very esthetic specimen. There are a lot of Aquas on the market from this area, this one is distinctly different and nice.
Garnet (pseudomorphed by Chlorite/Chamosite)
stock #8.1-445B
Michigamme, Marquette County
Michigan, United States
6.9 x 6 CM (cabinet)
price: $140


A big, sharp and fine example of the "aphrosiderite" pseudomorph of Garnet by a Chlorite mineral. These old classics from Michigan are usually not this good, this crystal has every face complete and is a the most perfect example I have handled, and at nearly 3 inches, that is remarkable. Nice black to greenish blue patina too. An old Wards label is included.
Elbaite tourmaline with Beryllonite
stock #8.1-446
Arqueana Mine
Minas Gerais, Brazil
8.4 x 6.2 CM (cabinet)
price: $1400


A fantastic combination specimen, this is NOT common! Immediately obvious is the big, two-tone green Elbaite just under 7 cm long and over 3 cm thick. That would be a very fine and attractive specimen on its own, but the matrix is composed of dozens of sharp terminated Beryllonites to 1.3 CM long. The overall condition is excellent, there is some minor chipping that is not easily seen from display angles.
Pyrite (Pyritohedral) with Dycrasite and Friburgite
stock #AC- 274
Eagle Mine, Gilman District, Eagle Co.
Colorado, United States
5.2 X 4.8 CM (miniature)
price: $50


well crystallized and classic for the mine this is almost all Pyrite with some Galena matrix. Magnification shows the "ugly grey-black" coatings on the pyrites are micros of Friburgite in "cruller" form with what appears to be Dycrasite. A good reference piece for this prolific mine and not that ugly overall!
HOLD Fluorite (flattened Dodecahedron)
stock #HOLD 6.2-186
Shangbao Pyrite Mine, Leiyang
Hunan Province, China
3.7 x 3.3 CM (miniature)
price: $40


This type of Fluorite is distinctive for the Shangbao mine. The dodecahedron is flattened as would be expected in a Spinel Twin, the six square faces of the original cube form are glass clear like windows into the crystal and the other adjacent faces are frosted. There are some pretty purple phantoms and the crystal cluster is clear enough to see a mass of creamy dolomite inside the fluorite. The backside is heavily contacted but overall the condition and presentation is good. A pretty and inexpensive piece!
