Quartz - Mt Tabor style tabular, gemmy
stock #19.1-368
Devils Den, Mount Tabor, Rutland County
Vermont, United States
2.3 x 1.3 x .7 (thumbnail)
price: $110


Small, perfect, gem clear, brilliantly lustrous tabular habit Quartz. From the recently described (May-June 2019 Rocks and Minerals magazine) Devils Den locality. These alpine style Quartz are not often available and are not well known outside the Northeastern USA. An excellent thumbnail example from this location and an attractive Quartz from anyplace. In fine condition as seen.
Quartz -"Mt Tabor type"
stock #19.1-366
Devils Den, Mount Tabor, Rutland County
Vermont, United States
3.2 x 2.2 x .6 CM (small miniature/ large thumbnail (toenail))
price: $130


Gem clear, doubly terminated Quartz from Devils Den that has a slight faden line, and several terminations in a line that share the same tabular prism faces. Some of this sort have been called "Mt Tabor Twins" though these are likely not a unique twin law but are quite distinctive and very unusual. The June 2019 Rocks and Minerals article describes the locality well and these alpine style USA Quartz are not often available on the market.
Quartz- faden, USA locality
stock #19.1-365
Devils Den, Mount Tabor, Rutland County
Vermont, United States
3.8 x 3 x 1.1 CM (miniature)
price: $85


The faden Quartz from the long known locality of Devils Den, Mt Tabor, Vermont is rarely seen. This site was recently described in the June, 2019 issue of Rocks and Minerals, and illustrates several unusual habits of Alpine style Quartz not often seen in the USA. This tabular transparent Quartz crystal shows a very distinct faden string as well as offset growth structures and recrystallized breaks. Some chipping exists at one end but the rest is undamaged. A nice gemmy transparent Faden from the USA not often available.
Aragonite on Calcite on Fluorite
stock #19.1-363
Cave-in-Rock, Hardin County
Illinois, United States
6.3 x 3.9 x 3.3 CM (cabinet)
price: $170


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.

stock #19.1-362
Stoneco Auglaize Quarry, Junction, Paulding County
Ohio, United States
8.2 x 5.9 x 3 CM (cabinet)
price: $150


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
stock #19.1-361
Shigar, Skardu District, Baltistan
Gilgit-Baltistan, Pakistan
2.9 x 2.4 x 2 CM (thumbnail)
price: $110


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.
Hydroxylherderite

Sassi, Gilgit district
Gilgit-Baltistan, Pakistan
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
Minas Gerais, Brazil
3.5 x 1.6 x 1.1 CM (small miniature/ large thumbnail (toenail))
price: $240


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.
