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.
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.
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.
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.
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!
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!
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.
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 !
