SOLD Boothite with Arsenolite (very rare hydrated Copper Sulfate)
stock #SOLD Alec 12-599
Baker, San Bernadino County
California, United States
6.5 x 3.6 x 3.5 CM (cabinet)
price: $0


Most "very Rare" minerals tend to be very tiny and very drab. This is an exception with bright blue sparkling masses of well formed crystals mixed with platy white Arsenolite crystals. This is similar to Chalcanthite but it has 7 H2O included making it "fully hydrated". This was part of the Ruth and Andy Palmer species research collection and was studied by Joe Mandarino. Almost never seen for sale and an exceptional example!
Rhodochrosite with minor Sphalerite, Pyrite, Quartz
stock #A7-548
Sweet Home Mine, Alma
Colorado, United States
2.6 x 1.7 x 1.1 CM (thumbnail)
price: $330


A well composed Rhodo thumbnail with great color from the Larry White collection. The piece is mostly just 3 rhombs juxtaposed with almost no matrix. Good translucency and luster this is a nice yet affordable example. The cost of any good Sweet Home specimens has consistently gone up every year, and since "they ain't makin 'em no more" the supply is now very small.
Brochantite- (rare stout crystals)
stock #Alec-3-481
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
4.9 x 3.7 x 3.9 CM (miniature)
price: $775


A well formed and undamaged specimen of the "stout" crystal habit found about 4 years ago at Milpillas. This locale is now world famous for some of the best Azurites, and the very best Brochantites ever seen. The Brochantites were mostly of the delicate "hairy" or fuzzy type, which were beautiful but incredibaly fragile. Only a few of the thicker crystals on matrix came out. The very best pieces sold quickly in the 5 and 6 figure range, few were available for collectors of "normal" means. This is one such- an excellent miniature example that is both esthetic and affordable. The largest crystal is 2.5 CM long and all have excellent luster.
Sulphur (native crystallized with petroleum inclusions)
stock #14.1-429
Girgenti
Sicily, Italy
7.1 x 4 x 6.4 CM (cabinet)
price: $500


A very attractive (and genuine natural) Sulfur with a sharp, well formed 3.2 CM crystal nicely perched on a calcite/ aragonite matrix. There are petroleum inclusions in the Sulfur that prove that this is natural and not one of the common fakes. An older (pre 1960's) piece with great composition, there are some tiny edge chips visible so this is not for a perfectionist. If perfect the price would be far more, but it is still an attractive, reasonable cost classic mineral specimen.
Rhodonite crystals (classic locale and habit)
stock #12.1-314
Franklin Mine, Franklin Mining District, Sussex County
New Jersey, United States
5.7 x 4.7 x 2.9 CM (cabinet)
price: $475


A well composed, classic Rhodonite specimen from the great Franklin New Jersey that has fine form and color. This cluster has some well terminated crystals up to 3.3 cm long and is above average. Collected over 50 years ago, this has the classic form of blocky, red-pink, somewhat crude crystals with minor calcite associated. At one time these were found in any good USA collection, but they are now quite scarce in any quality.
Rhodonite (gemmy crystals) on Galena
stock #13.1-317
Broken Hill, Yancowinna County
New South Wales, Australia
3.1 x 2 x 1.9 CM (small miniature/ large thumbnail (toenail))
price: $850


A single, brilliant dark red gemmy Rhodonite crystal is exposed in a mass of silvery Galena. The Rhodonite is 2.3 CM across, and has very bright luster. Typical crude but complete edges are undamaged. This is the classic form for Broken hill Rhodonite,but the gemmyness, size and deep color are far better than average.
Fluorite (alternating color faces, internal bubbles)
stock #Alec 29-035
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
4.4 x 3.2 x 2.6 CM (miniature)
price: $2600


A killer miniature with a perfect 3 CM fluorite (complete all around) neatly perched on calcite matrix. Great architecture and esthetics, but what sets this apart is the faces have alternating colors! The slightly frosted deep blue faces offset from the glass clear faces that have a white to lilac-purple color. The interior is seen clearly through the unfrosted windows and is almost colorless. Looking closer the inside is loaded with bubbles, the larger ones are frozen inside negative crystals but some very tiny bubbles move slowly in their oil filled cavities. There are also complete internal cubes and partial cubes to be seen with magnification. Absolutely fascinating, attractive and even better in person. Even after seeing thousands of Huangang specimens this one is a significant standout.
Malachite- Stalactititic "cauliflower"
stock # Alec 24-096
Luishia Mine, Katanga Province
, Democratic Republic of Congo (Zaire)
5.3 x 4 x 1.5 CM (small cabinet/ large miniature)
price: $385


Unusual form, attractive and elegant small cabinet specimen of Malachite from the Congo. Malachite is a rather common mineral and often not given very much respect since it is so abundant. It takes a very good specimen to get noticed. The copper belt of the Congo has yielded some of the most beautiful Malachites of all time. The best show a wetlook luster, are chantoyant chantoyance, have rich color and attractive form. This has all that and is in excellent condition.
