Tetrahedrite - classic Utah
stock #AC-068
Bingham Canyon, Bingham Mining district, Salt lake County
Utah, United States
8.8 x 67.2 x 5.8 CM (cabinet)
price: $230


Well-crystallized sizable specimen of lustrous Tetrahedrite with some Pyrite as well. A rich chunk from the famed Bingham Canyon deposit, ex Schortmann Minerals. The label address gives a date range for this piece of 1937-1946 at their shop. It is clearly from the early era of mining. The area had several mines at that time which began in 1903, but in 1936 Kennecott bought out the previous operations and eventually this became one of the largest open pit mines in the world. This piece is quite choice, densely packed with crystals and was priced at a hefty $4.00 at that time. A lot of money in that time some 70-80 years ago!

Wardite and Crandallite - USA classic
stock #22.1-357
Little Green Monster Mine, Clay Canyon
Utah, United States
6.3 5.4 x 2.1 CM (cabinet)
price: $290
Fall 22

A half nodule of classic Fairfield Utah Phosphate minerals. An older specimen from the era of Over and Montgomery (1930s) at the Green Monster Mine, this is lightly polished and shows well-defined banding of species. The white core of this is likely Fluorapatite but it has not been analyzed.

Variscite with Crandallite and Wardite - classic US
stock #21.1-331
Little Green Monster Mine, Clay Canyon
Utah, United States
7.7 x 4.5 x 1.9 CM (cabinet)
price: $380
New Year 22

A half nodule from the famed Variscite locality of Clay Canyon. This is quite an unusual nodule, it has complex zoned "eyes" showing these three Phosphates in concentric circles. An impressive illustration of the sequential deposition and alteration of these minerals, the details are especially striking. With good magnification it can be seen that there are small open cavities between some of the rings which contain micro crystals of other unidentified species. An early piece from the classic finds by Ed Over and Arthur Montgomery. In excellent condition, the color is a little brighter in person, overall a choice and mineralogically interesting piece of a type I have never seen before.

Gordonite (rare Phosphate) on Variscite, type locality
stock #20.1-139
Little Green Monster Mine, Clay Canyon
Utah, United States
3.4 x 2.7 x 1.9 CM (small miniature/ large thumbnail (toenail))
price: $450
New Year 22

A rind of tiny, glassy Gordonite crystals on a Variscite nodule that has a tiny bit of Crandallite as well. From the type locality in Utah. This is the type locality for this specie found during the famed excavation project by Ed Over and Arthur Montgomery in the 1930's. The individual micro crystals are up to 1.5 MM in size, which is fairly large for the specie. These are both isolated, free standing and in radiating sprays. Remarkably the main cluster of crystals extends across 1.5 CM which makes this specimen an incredibly rich example, very fine for this rare specie.

Topaz on Rhyolite
stock #21.1-336
Topaz Mountain, Thomas Range, Juab County
Utah, United States
6.4 x 5.6 x 5.7 CM (cabinet)
price: $490
Late Summer 2021

A perfect, gem clear sherry colored Topaz crystal perched on a hard Rhyolite matrix. This classic locality is famed for Topaz and this is an especially choice piece with unusual perfection and no fading to the rich color. Even under 20x magnification this is undamaged. This does not have dark inclusions or interior cleaving lines inside as most do, it is eye-clean gem. This zone continues to produce a few nice pieces each year to dedicated diggers but the quality of this piece is far beyond most found. Most crystals of this size or larger are far less clear or even opaque.

Variscite half nodule with Crandallite and Wardite
stock #21.1-330
Little Green Monster Mine, Clay Canyon
Utah, United States
7 x 5.5 x 3.2 CM (cabinet)
price: $450
Late Summer 2021

A complete half nodule of colorful phosphate minerals from this famed, classic US locality. The nodule has a full mineralized edge rim in perfect condition with no chipping or missing bits which is most desired. The color zoning of the bright yellow to greenish Crandallite is especially distinct on this specimen, it has a clear separation line and contrasts well with the inner white and green interior. This piece is from the early excavations at this site by the legendary team of Over and Montgomery. Choice and better in person.

Mixite - historic specimen
stock #AX-35-144
Mammoth Mine, Tintic Mountains, Juab County
Utah, United States
7.6 x 4.5 x 2.7 CM (cabinet)
price: $320
new year 2021

This specimen dates to the famed Levison collection (New York City) acquired in 1899. Mixite is considered fairly rare, an unusual Bismuth Copper Arsenate, almost never seen in display specimens. This is a sizable and complex multi-specie piece with a Barite matrix hosting areas of Mixite, Malachite plus what seems to be Olivenite. There are a few additional small crystals not identified. The Mammoth area of Tintic was a fantastic locality that provided some rare and exotic species including five new minerals. This specimen has a very tattered old label affixed (not easy to read) and we also include a photocopy of the page from his collection ledger for this piece. A nice example in a sizable specimen.

Smithsonite with Hemimorphite
stock #0770-JM-4361
Hidden Treasure Mine,Oquirrh Mts. Tooele County
Utah, United States
7.8 x 6.7 x 3.8 CM (cabinet)
price: $490
new year 2021

Choice old Smithsonite with botryoidal blue-green surface sprinkled with lustrous small Hemimorphite crystals. Ex. John Marshall collection, a fine piece from the Hidden Treasure Mine (Utah); this is more than 40 years old. The matrix is especially nice as it shows the unusual layered stacking of Smithsonite and has spaces between each layer. The Hidden Treasure Mine is just that, - A less well-known or hidden treasure which has produced some fantastic specimens.
