Chrome Tremolite
stock #8BURE 881
Mogok, Pyin-oo-Lwin District
Mandalay division, Burma (Myanmar)
5.9 x 3.6 CM (small cabinet/ large miniature)
price: $200


A single sizable (3 CM) crystal of rich green Chrome tremolite sits on a calcite matrix. The crystal form is impressively sharp for one of such size, this is not the typical "blob" of tremolite! Great color and gemmy on thin edges, these are not common in general and rare in such aesthetic specimen.
Sphalerite with Quartz
stock #8.1-439
Krushev Dol Mine, Madan, Rhodope Mts.
Smolyan Oblast, Bulgaria
10.4 x 7.5 CM (cabinet)
price: $325


As a rule, black Sphalerite is not a very desirable mineral, but this one is something special! Lusterous and sharp glassy Sphalerites to almost 3 CM are decorated with treelike growths of slender quartz crystals. In great condition and with killer esthetics, the Sphalerites are well positioned and show complex growth hillocks on many faces. Careful examination finds only minor edge wear on some sphalerites, nothing distracting from the impact of this piece. Great for this specie and exceptional for this famous mineral region!
Sphalerite with Chalcopyrite
stock #7-TRI-578
Tri State District, Ottawa County
Oklahoma, United States
15 x 9.7 CM (cabinet)
price: $500


A very old and very fine Tri-state classic! Ex collection of the Arizona-Sonora Desert Museum, This is a true top shelf specimen. Sphalerites here reach to 4 CM and are exceptionally well formed. The smaller crystals are a fine ruby red (rubyjack) while the larger ones are darker and coated with chalcopyrites. Some faces are noticably irridescent and over all the luster is outstanding. The only damage is at the outer edges where it would be expected, the display face is pristine, three dimensional and very esthetic. The old Tri-state area produced a lot of materials in its time, but this quality was excellent even in its heyday.
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.
HOLD Garnet (pseudomorphed by Chlorite/Chamosite)
stock #HOLD 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.
