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!
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 !
Serpierite with Ktenasite
stock #8 GRC-1006
Kamereza Mines, Aglos Konstantinos
Attiki Prefecture Laurion District,
10.7 x 7 CM (cabinet)
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!
