Apatite CaF on Calcite - classic Canadian
stock #21.1-354
Faraday Mine, Farady Township, Bancroft District, Hastings County
Ontario, Canada
9.1 x 5.4 x 2.9 CM (cabinet)
price: $380


A fine, large doubly terminated Apatite crystal sits on an orange Calcite matrix. The Apatite is well-formed with the typical slightly rounded edges and two different types of termination. Fluorapatites are fairly common in the scattered Skarns of this region but substantial crystals like this are not found very often. There are some minor contacts but overall this is a distinctive textbook form crystal with some areas of glassy luster. A modern classic.

Malachite pseudo after Azurite - USA classic
stock #15.1-362
Sacramento Mine, Bisbee, Warren District, Mule Mtns, Cochise Co.
Arizona, United States
3.8 x 3 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $650


A textbook perfect pseudomorph that has the exact form of the original Azurite crystal fully altered to a velvety Malachite. A few tiny bits of Cuprite and Copper are seen with strong magnification on the gossan matrix, but overall this is all about the very fine Malachite. A classic US specimen from the Sacremento Mine at Bisbee, we are told this is from a pre 1929 collection but there are no old labels. Certainly no specimens of this quality have been found for many decades, and will not be seen again.

SOLD Fluorite on Calcite - unusual locale
stock #SOLD 21.1-353
Saint-Honore, Saguenay-Lac-Saint-Jean
Quebec, Canada
7.9 x 6.6 x 5.1 CM (cabinet)
price: $0


Two different forms of Fluorite on Calcite matrix sprinkled with Chalcopyrite crystals. The Fluorite cubes are very sharp, gemmy zoned and vividly fluorescent. The pink portions of the Calcite are also fluorescent making a nice contrast of purple, red and cream colors. The Fluorite cubes are up to 8mm in size and in perfect condition. The cores are a yellow hue with a blue outer zone. We almost never see this locality represented in Fluorite collections but it is clear it was capable of forming some very nice crystals.

Pollucite - gemmy etched crystal mass
stock #8.AE-842
Paprok, Kamdesh District
Konar Province, Afghanistan
4.4 x 3.2 x 2.9 CM (miniature)
price: $110


A transparent and nearly pure crystallized Pollucite that has been heavily etched. Aside from some tiny inclusions this is all Pollucite with total transparency, and curved crystal faces. Pollucite is one of the few sources of Cesium and sometimes also includes substantial amounts of Rubidium, it is an uncommon gemstone as well. The specimen is broken on the base or underside where it was attached but the visible surfaces are in fine condition and show the characteristic Pollucite structure and luster perfectly. This is just under 36 grams of gem crystal that is very lustrous in person.

Quartz with Hedenbergite inclusions and Andradite
stock #8.AE-920
Sinerechenskoe, Kavalerovo mining district, Primorsky Krai
Far Eastern Region, Russia
5.2 x 3 x 2.4 CM (small cabinet/ large miniature)
price: $220


A nice combination specimen of dark green (nearly black from some angles) Quartz clustered on Andradite. The Garnets are tiny sparkling orange color and make a nice contrast. In very good condition as seen, the Quartz shows the classic form where it gets wider toward the termination, yet is not a scepter. Presents well from several angles with a good balance.

Albite - vintage specimen var. Adularia
stock #21.1-078
Greiner (Greinerberg) Finkenberg, Zillertal, Schwatz District
Tyrol, Austria
4.7 x 3.1 x 1.5 CM (miniature)
price: $80


Gemmy and bright small Adularia crystals in two generations on a thin matrix plate. This specimen comes in an antique handmade display box of cardboard that has had a round hole cut into the top and a glass sheet installed. Old labels are included. The specimen is in excellent condition, the labels reference an early alpine locality now known as the Greiner area of Schwatz, Tyrol. All of the Adularia are transparent on close exam. Unfortunately it is impossible to know the exact vintage of this piece or the names of the early collectors but it is still a very nice antique presentation.

Stilbite with Apophyllite
stock #19.1-278
Nasik
Maharashtra, India
9.1 x 6.4 x 3.8 CM (cabinet)
price: $350


We do not often offer Indian Zeolite minerals as there are so many in the market and few stand out. However these can be both exceptionally esthetic and reasonable in price. This vivid orange spray of perfect Stilbites is that sort of specimen. The matrix is a jumble of Apophyllite crystals with off white porcelain luster that make a fine contrast to the orange. In perfect condition and with classic form, this is more impressive in person. Well selected Indian minerals are some of the greatest bargains in the mineral world, they offer perfection, color, esthetics and elegant forms at a low cost. This is that sort of specimen.

Phenakite - gem Brazilian crystal
stock #21.1-290
Rio Piracicaba
Minas Gerais, Brazil
2.6 x 1.7 x 1.5CM (thumbnail)
price: $360


A hefty (7.6 gram), sharp and glassy Phenakite crystal from old finds in Minas Gerais (Brazil). It is hard to be certain but it certainly looks like this crystal is twinned; most are. The underside (or backside) has a large rehealed and recrystallized area that had been broken long ago. There is an unhealed break on one edge so this is not perfect 360 degrees but the display side looks flawless. The transparency and luster are great in person, this is a good sized and flashy crystal from a locality that has become a classic in Brazil but seems to be no longer producing.
