Polybasite on Acanthite
stock #20.1-112
Guanajuato, Municipio de Guanajuato
Guanajuato, Mexico
3.2 x 2.4 x 1.7 CM (thumbnail)
price: $3200

A killer specimen with exceptional form, the main crystal being textbook perfect, sharp and perfectly defined. Formerly in the collections of Carl Acosta and Brett Keller, this is just barely within the size limit to be classified a thumbnail. The Acanthite matrix is the "melted" look type and is a fine contrast to the large Polybasite. Displays well from either side, what we consider to be the front or best view has a nice metallic patina. Most of the Polybasite we have seen from Guanajuato is more crude or has overgrowths of Pyrite, this is just a superb example of the specie and extraordinary for the locality.

Prehnite and Apophyllite - classic locale
stock #17.1-649
Loanhead Quarry, Beith
Strathclyde, Scotland
5.9 x 4.7 x 3.4 CM (cabinet)
price: $290

Yellow Prehnite in a crystalline ball from the Loanhead Quarry, Scotland. A single gem clear Apophyllite crystal is a fine contrast. From the Les Hitchings collection, this was collected by him in 1974 during an extended trip to Scotland where he spent weeks digging in the Glasgow area. This was the best Prehnite he obtained.

Copper - well-crystallized
stock #6.2-807
Tongshan Mine, Guichi Dist., Chizhou Pref.
Anhui Province, China
6.8 x 4.8 x 5.3 CM (cabinet)
price: $650

Well-defined, sharp Copper crystals from China are very rare on the market, nearly non-existent. I can not recall seeing better formed crystals than these, most are quite crude or flat habit. These crystals are very well formed, mostly dodecahedral with some modified cubes. The Copper matrix is a spongy mass with a reddish color composed of more tiny copper crystals and masses. A nice copper from anyplace but outstanding from China. We obtained this in China in 2008, sold it then and now have it back again.

Galena - skeletal, hoppered crystals
stock #20.1-288
San Carlos Mine, Municipio de Maunuel Benavidas
Chihuahua, Mexico
10 x 7.1 x 4.7 CM (cabinet)
price: $950

Incredible,an older (1952) Mexican Galena with textbook perfect hoppered, skeletal form crystals. This specimen is from the San Carlos Mine, which in the late 1950 era produced some world class Vanadinite. After many years with no specimens, the mine again produced fine Vanadinites and Wulfenites in 1980 and 2018. We have never seen any other good specimens of Galena from this locale, and this is a choice piece from anyplace. The Galena has a dull luster from micro a micro druze of Anglesite and some Calcite. The forms range from deep hoppers with geometric ridges to intersecting boxes and even spirals. From the collection of Skylar Alverson obtained from G. Hixon in 1952. Outstanding condition and form, just a super Galena and a choice Mexican specimen.

Citrine -Doubly terminated Quartz
stock #20.1-286

North-Western Province, Zambia
9.2 x 1.7 x 1 CM (cabinet)
price: $170

A single Quartz prism, doubly terminated and complete all around with a color range from light yellow to a darker orange yellow at the tips. From a find about 3 years ago in Zambia, the best locality informaqtion we have is North-Western Province. The habit and form is quite different from the other Zambian locale in Luapula. If this locality produces again we will likely get better details on the exact source, but until there is more info we can still appreciate the quality of these specimens. All of the faces have a light frosting but the interior is gem clear with no clouding. The crystals were sold as gem rough but a few choice pieces were saved uncut.

Hematite -well crystallized
stock #18-AX-14-355
N Chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
5.2 x 3.8 x 2.9 CM (cabinet)
price: $320

Stacks of sharp disk like crystals with bright luster from the famed N'Chwaning mine. From the finds over two decades ago this specimen is in outstanding condition, the only damage is on the small area of the base where it was removed. Some of the clusters are rosette-like but the aligned stacks are dominant and quite differnt from the well-known Alpine habits of Hematite.This can be displayed in most any orientation and is much more impressive in person. The edges of the crystals are quite sharp and well defined.

stock #20.1-285
Goanikontes Claim, Goanikontes, Arandis
Erongo Region, Namibia
5.7 x 4.4 x 2.9 CM (cabinet)
price: $220

Several delicate sprays of Boltwoodite crystals up to 1.3 CM (quite large for the specie) from Namibia. The small Uranium prospect at Goanikantes (Erongo region) was once the source of the worlds best Boltwoodites. This is a good example with moderate yellow color and nice contrast to the dark matrix. We can deliver this at any of the shows we attend but shipping must be arranged in advance.

stock #20.1-287
Daoping Mine, Gongcheng County, Guilin Prefecture
Guangxi Province, China
4.7 x 3.2 x 1.7 CM (miniature)
price: $880

Elongated chain crystals in an intricate cluster showing exceptionally bright color and luster. The form and overall display esthetics clearly show why the Daoping mine is considered by many as the greatest Pyromorphite locality in the world. This piece displays super well from any angle and has a lot of visual impact. In fine condition as seen, this is almost a complete "floater" just a tiny contact on the base and on the back, the front side is flawless and shows beautifully the epitaxial alignment of the stacked crystals. A lot of good pyromorphite came from Daoping from 2000 to 2017, but top grade pieces have always been uncommon and desirable.
