SOLD Quartz -Faden, Mt. Tabor Style
stock #SOLD 19.1-367
Devils Den, Mount Tabor, Rutland County
Vermont, United States
2.7 x 1.8 x .7 CM (thumbnail)
price: $0


The Quartz of Devils dens on Mt Tabor was recently (May-June 2019) described in a fine article in Rocks and Minerals. Not well known outside the Northeastern USA, these Quartz can take many habits and are often gem clear, alpine style. This doubly terminated example is very unusual with a Gwindel like twist or rotation, a series of almost aligned terminations and a wide Faden line or string through the center. There has been some discussion if these can be called Gwindels and they do seem to meet the basic definition. In excellent condition, very clear and sharp.
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.

Jeffrey Mine, Asbestos
Quebec, Canada

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.

stock #19.1-363
Cave-in-Rock, Hardin County
Illinois, United States

price: $170


An unusual old specimen from Cave in Rock, southern Illinois.

Some of the Calcites have stair-stepped epitaxial growths along the prisms.
