Garnet (pseudomorphed by Chlorite/Chamosite)
stock #8.1-445B
Michigamme, Marquette County
Michigan, United States
6.9 x 6 CM (cabinet)
price: $2180


A big, sharp and fine example of the "aphrosiderite" psudomorph 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!
Fluorite (flattened Dodecahedron)
stock #6.2-186
Shangbao Pyrite Mine, Leiyang
Hunan, 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!
Mimetite on Philipsbornite
stock #8 Pb-991
Hat Yai District
Songkhlei Province, Thailand
4.3 x 3 CM (miniature)
price: $350


A very fine example of the better quality mimetite that had come from this area of Southern Thailand. There has been no more of this for several years and the area is considered unworkable now due to political problems. This is a lusterous sparkling miniature of glassy yellow crystals. This location is one of a very few great localities for crystalized mimetite worldwide. Like most others (Tsumeb, Pingtouling etc) Hat Yai no longer produces anything. Good specimens are fast becoming classics, and this is one.
Grossular Garnet (chromian var. Tsavorite)
stock #9.1-137
Mine Lac dAmiante (Black Lake Mine), Megantic County
Quebec, Canada
2.9 x 2.7 CM (thumbnail)
price: $350


A brilliant thumbnail of electric green gem garnets on matrix. For intense color and luster this is really as good as any of these can get. The largest crystal is 7mm, about the biggest size that can still have such a deep green color. Displays great, we have not seen any of this quality for many years !
Serpierite with Ktenasite
stock #8 GRC-1006
Kamereza Mines, Aglos Konstantinos
Attiki Prefecture Laurion District, Greece
10.7 x 7 CM (cabinet)
price: $200


A bright, sparkling and very 3 dimensional piece of these two rare minerals from the classic locality of Laurion. Excellent coverage and color. Serpierite is a sky blue hydrated sulfate and the mid member of the Deviline and Rapidcreekite series. It is nice to have a rare mineral that is also cabinet sized and pretty since this is usually available just as micro specimens!
Bournonite cogswheel
stock #6.2-891
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
3.4 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $400


We have all seen a lot of Bournonite from Yaoganxian, some is world class, but most has a lot of serious damage. Clean examples of this brittle mineralare quite rare, and to find a nearly pristine "cogswheel" type that is crystalized all around (floater) is very special. This complex cluster has excellent mirror bright metallic luster, great form and esthetics. Very careful examination shows a few hard to find chips all under 1 mm in size, not distracting at all. For some reason, there have been more single, prismatic type crystals from Yaogangxian, this example looks much more English than Chinese! Super reasonable !
