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!
Yaogangxian Mine, Yizhang County
3.4 x 2.6 CM (small miniature/ large thumbnail (toenail))
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 !
Fine pink to honey color gem garnets in a dense cluster on matrix. Crystals to 8mm showing excellent luster., from the classic and now famous Jeffrey Mine. Some assocated vesuvianite and micro diopside too. Minimal damage, except at the edges where removed, this is a nice yet affordable older piece from the 60's.
