SOLD Wulfenite with Smithsonite (Co)
stock #SOLD 23.1-598
Tsumeb
Otjikoto Region, Namibia
4.2 x 3.9 x 2.4 CM (small miniature)
price: $0


Small but pretty miniature from Tsumeb of course. The Smithsonite is well-crystalized with gemmy dark pink color that is almost purple. Scattered in this are gemmy butterscotch yellow-orange Wulfenites that are also gemmy. The matrix is a nice contrast and the whole is in excellent condition. Many pink Smithsonites are mistakenly called Cobaltoan when often the color is actually from Manganese, Iron or another source. We are fairly sure this is indeed Cobaltoan Smithsonite based on the paragenesis and match to another well-tested sample. No matter the chromophore here the specimen is richly colorful, attractive and a very nice association that is not crazy expensive for one of these.

Aurichalcite
stock #AX-10-868
Mina Ojuela, Mapimi
Durango, Mexico
7.3 x 6.8 x 3.8 CM (cabinet)
price: $420


A rich and large vug of Aurichalcite crystals in hairlike masses and clusters. Excellent color and in very fine condition. A classic from Mina Ojuela, this is a fairly old (1970-80 era) specimen and far better than the usual seen from this locality .It has a very large blue zone, long hairs (to well over 1 CM) in thick layers and has real display impact. Very few minerals in the world have this exact color, it stands out in any cabinet!

Spinel on Marble- classic Mogog red
stock #24.1-181
Pein Pyit, Mogok, Pyin-Oo-Lwin District
Mandalay Division, Myanmar (Burma)
3.1 x 2.4 x 2.2 CM (thumbnail)
price: $160


A single bright red crystal of Spinel sits on a small mass of pure white Marble. The form is a modified octahedron and is undamaged, complete and presents well. This is classic Mogok material, the crystal is vividly fluorescent and displays well from all sides. This is a small and affordable version of the top larger Spinels that are known from here which typically sell at incredibly high prices.

Topaz - clear gem crystal
stock #24.1-182
Sakangyi-Kyauk-Pyat-That, Mogok, Pyin-Oo-Lwin,
Mandalay Division, Myanmar (Burma)
2.7 x 1.8 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $240


Sharp and water-clear transparent Topaz crystal with very bright luster. From the pegmatite of Sakangyi, it is perfectly formed and undamaged. Sadly the current state in Myanmar is very much in chaos and no mining of any sort is going on. This may take a very long time to resolve. The complex mineralogy of this region has produced many incredible finds and is of course world famed for the gem Corundum found there. Topaz like this can be fantastic, showing these very elegant and complex terminations, prism modifications and very sharp form.

Rhodochrosite - unusual locality
stock #24.1-180
Olpe, Arnsberg
North Rhine-Westphalia, Germany
2.4 x 1.7x 1.2 CM (thumbnail)
price: $280


Small but well-formed scalenohedral crystals with good pink-red color form a druse on matrix. I have never seen another Rhodochrosite from this locality but it is listed as a specie found there by Mindat, though there are no photos of examples. The mines in this site are quite sizable and produce Barite as well as Lead and Zinc. Several Manganese minerals are noted as well. We can not find any published examples from this mine and only two examples from all of Arnsberg are on Mindat, so it is safe to say it is a fairly rare occurrence. A nice thumbnail and a good addition to a German collection or a Rhodochrosite suite.

Pecoraite ps after Millerite with Millerite
stock #24.1-179
Sterling Mine, Antwerp, Jefferson County
New York, United States
6.4 x 3.3 x 2.8 CM (cabinet)
price: $290


Pecoraite can be seen as a greenish alteration of Millerite crystals along with some unaltered Millerite in vugs. A quite rare specie worldwide and also rare from the famed Sterling Mine locality, this specimen was in the collection of Skylar Alverson which he obtained in 1980. The matrix is the classic Iron ore most likely Hematite with tiny Quartz, Dolomite and Chalcopyrite crystals. The hairlike crystals are mostly brassy unaltered Millerite but some show the alteration and are no longer metallic. Millerite from Sterling Mine is quite sought after, the Pecoraite is much more rare and the two together are a nice combination. Please note, these are quite tiny crystals, well visible by naked eye but really not a display type specimen, it is best appreciated with magnification.

Schizolite with Kupletskite and Calcioancylite etc.
stock #23.1-156
Mont Saint-Hilaire, Monteregie
Quebec, Canada
6.8 x 3.4 x 2.7 CM (cabinet)
price: $390


An outstanding assemblage of well-crystalized uncommon minerals from the famed Mt St. Hilaire. The large pink Schizolite crystals are slightly radiating and reach over 5 CM. Schiziolite from this locality had been misidentified for decades as Serandite, which also is found there. The Kupletskite is in two forms thin blades in sprays and larger more blocky crystals. The Calcioancylite is less noticeable in very tiny white crystals. Attractive and uncommon species are well-presented in this well-crystalized Alkaline assemblage.

Wulfenite with Duftite, Conichalcite and Mottramite
stock #21.1-474
Tsumeb
Otjikoto Region, Namibia
7.6 x 5.8 x 4.2 CM (cabinet)
price: $860


Striking, colorful and complex specimen with well-defined Wulfenite crystals that are partly to fully overgrown with bright green secondary copper minerals. In fine condition as seen, the largest Wulfenites are over 1.5 CM with a butterscotch orange color. Tsumeb is famed for its great specimens with diverse species, habits, colors and chemistries. The results are sometimes especially attractive like this. The associations here are especially impressive.
