Small but very impressive thumbnail of intense green Garnets sitting on a druze of tiny Diopside crystals. The Diopside is slightly greenish in color and is fluorescent a bright yellow while the Grossular (in 450 NM light) is a brilliant red. Even without this very rare response for a garnet, the specimen is super attractive, the Garnets are gem clear, lustrous, sharp and undamaged. From the great Jeffrey mine, this is a tiny treasure.
An unusual old specimen from Cave in Rock, southern Illinois. Etched Yellow Fluorite with a hint of purple zoning is the matrix for a treelike spray of slender spikey Calcite crystals that are coated with secondary aragonite. Some of the Calcites have stair-stepped epitaxial growths along the prisms. Ex Larry Conklin with his label, This looks very much like some Minerva #1 mine specimens but Conklins laberl only lists Cave in Rock. A delicate, sculptural piece that is also somewhat fluorescent.
The Auglaize Quarry of Ohio is a famed locality in the Finley Arch zone. It is famed for small pockets of Fluorites that can be very sharp and iridescent. This is a nice example of the this locale which is no longer open for collecting. The Fluorites are very lustrous, those that are in the protection of the vug are in fine, undamaged condition. All have the classic "root beer" brown color and show multi color iridescence. As is usually the case these are also brightly fluorescent.
Beryl V. Aquamarine
Shigar, Skardu District, Baltistan
2.9 x 2.4 x 2 CM (thumbnail)
A clean thumbnail of gem clear Aquamarine on an Albite matrix. The Beryl is flattened along one axis and has the classic flat termination. In perfect condition, super transparent, the crystal faces are mostly flat with minimal striation. Overall a choice small gem from the great Shigar pegmatite zone.
Sassi, Gilgit district
3.9 x 2.3 x 1.9 CM (small miniature/ large thumbnail (toenail))
A shard of feldspar matrix hosts a glassy green Herderite crystal in fine condition. Intensely fluorescent, the crystal shows sharp edge modifications and striated faces. From a find in 2005, the crystal here is 2.3 CM in diameter and transparent to translucent. Choice with no visible damage.
Spessartine - etched gem crystal
stock #18-AX-7 060-(617)
Pederniera Claim, Sao Jose da Safira, Doce Valley
3.5 x 1.6 x 1.1 CM (small miniature/ large thumbnail (toenail))
A fine, complete floater of naturally etched gem quality Spessartine from an unusual locale. This is an older piece from the famed Pederneira Mine ex. Larry White collection. Similar to the better known Navegadora Spessartine, we have only seen one other example from this locality. Like a modern cityscape or sculpture, this is a fine example of this Garnet habit. Completely translucent to transparent, this is all gem grade, with backlighting (the photos are not backlit) it glows a bright red. In undamaged condition, the geometric etchings and crystal forms are especially sharp on this toenail sized piece.
Remarkable, super large Bornite crystals in a cluster from Zambia. Bornite is a common ore mineral that is surprisingly rare in crystalized form. Large and distinct crystals are far more rare yet. This cluster of big crystals has a well defined form, sharp edges, striated faces and a nice dark blue patina. There is no matrix, just Bornite. Nachanga is one of the major mines in Zambia, worked for Coper and Cobalt. This locality has produced some exciting and fine specimens but they are only rarely available. This is by far the best Bornite I have seen from this mine.
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
4.6 x 3.2 x 1.4 CM (miniature)
A very delicate cluster of clear "windowpane" Wulfenites on contrasting dark Gossan matrix. From the Silver Bill mine, a very important Arizona locality that is less often seen available in choice pieces. All the main crystals here are perfect and damage free, only a tiny crystal at one edge is broken. This is in incredible condition given the fragility. The Silver Bill was at one time open to mineral collectors since it shut down, and a few choice things were found on occasion. Mining began here in 1893 and the best specimens were found long ago. Good Wulfenites were never as common as at the more famed mines like Glove and Red Cloud, but they can be impressive and quite unlike specimens from these other localities. Choice.
