SOLD Gratonite
stock #SOLD 13.1-380
Excelsior Mine, Cerro de Pasco, Pasco Province
Pasco Department, Peru
3.3 x 2.2 x 2 CM (miniature)
price: $0
pre Tucson 2015 update

A small crystallized specimen of the rare mineral Gratonite from the only find of good specimens some years ago at the Excelsior mine. This is not typically a pretty mineral, and this will not win any beauty contest, but here are several habits of distinct crystals, albeit with some tiny zones of damage. A good reference specimen of a rare mineral that is also very affordable.
Zoisite (gem crystal from Pakistan)
stock #8.AE-870
Alchuri, Shigar Valley, Skardu District, Baltistan
Northern Areas, Pakistan
2.9 x 1 x .5 CM (miniature)
price: $240
pre Tucson 2015 update

A gem clear Zoisite crystal that is not at all like the usual from Tanzania. This is a nice small example with well defined striations and habit that is also distinct and shows dichroism. This came out over 10 years ago and since then we have not seen any. A minor chip is noted with magnification so this is not for the picky perfectionist, but it is a nice displayable gem crystal that is affordable. A rare example from an unusual locality.
Calcite & Quartz (cumberland habit)
stock #ALEC-20-155
Sa Ducessa Mine, Oridda, Carbonia-Iglesias Prov.
Sardinia, Italy
5 x 3.7 x 3 CM (miniature)
price: $200
pre Tucson 2015 update

An odd yet attractive very old Sardinian Calcite specimen with a second generation of Quartz in "Cumberland Habit". The quartz also has numerous inclusion and some is in stacked groupings. There is considerable hematite on and in many crystals here adding nice color contrast. In good condition and attractive, most everything is doubly terminated.
Azurite on Anglesite over Cerussite etc.
stock #ALEC-24-393
Tsumeb
Otjikoto Region, Namibia
3.5 x 2.1 x 2.9 CM (miniature)
price: $2900
pre Tucson 2015 update

An exceptional Tsumeb specimen that is both esthetic and really different. Ex. Sussmann Collection, this has the form of blocky Cerussite crystals that are fully encased in smaller Anglesite crystals. Some of the Anglesite shows inclusions and overgrowths of Malachite and Linarite. The Azurite crystals are the finishing touch and these are very fine, electric blue and with top luster. The whole displays very well, the color contrast is excellent and I have never seen this style presentation in any other Tsumeb piece.
Fluorite with Phantoms
stock #ALEC-20-157
Cave-in-Rock, Hardin County
Illinois, United States
8.2 x 6.7 x 4.5 CM (cabinet)
price: $700
pre Tucson 2015 update

Excellent form and sharp edged cubes typify this fine old Cave in Rock Fluorite. In excellent condition and with a nice contrasting matrix of tiny golden Sphalerites and white Calcites. Moderate backlighting makes this glow deep purple hues and the phantoms are very evident. Backside contacting is typical but the 3 dimensional presentation is much better than usual.
Fluorite
stock #ALEC-20-071
Elmwood Mine, Carthage
Tennessee, United States
4 x 3.2 x 3.2 CM (miniature)
price: $320
pre Tucson 2015 update

Good Fluorite from the Elmwood mine is always desirable but the mine is mostly producing Calcite now. This is a small but quite nice specimen that sits on a contrasting matrix. Nice zoning and clarity, this one has the delicate surface steps and it is possible to see the matrix through the Fluorite. A modern American classic, still affordable for now, but attractive enough for any collection.
Calcite included by Realgar
stock #8.1-123
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan, China
3.1 x 2.9 x 2.5 CM (miniature)
price: $140
pre Tucson 2015 update

We have seen very few of these esthetic Calcites from the Shimen mine, and none for several years. This was obtained in China in 2002, it is a single gemmy Calcite included by and associated with blood red Realgar. The crystal displays well and the staining of the orange-red color adds a very attractive touch.
Weloganite with Dresserite, Dawsonite
stock #ALEC-10-946
Francon Quarry - Montreal
Quebec, Canada
8.5 x 8.1 x 5.6 CM (cabinet)
price: $290
pre Tucson 2015 update

A sizable cavity filled with sharp Weloganite crystals up to 2.2 CM long. There are numerous tiny crystals of the classic related species (and probably some Strontianites too. The Francon Quarry is now gone, its Weloganites were by far the best ever found worldwide. The biggest of these are undamaged with the elegant complex hourglass habit well presented. There are some "natural" broken crystals in the pocket that show signs of partial rehealing. A good, affordable specimen with some well formed, rare crystals.
