Really fine form and rich color on this specimen from the recent finds at Luputo. The pseudomorph retains the shape of the original Azurite crystals that were rep[laced by Malachite and finally replaced by the blue Chrysocolla. The delicate array of crystals is on a Gossan matrix and in excellent condition despite the fragility. The discovery of this material made big news in the mineral world. This is a choice example with particularly distinct crystal shapes well presented.
Barite - Phantom crystal
stock #AX-22-180
Muddy Creek, Rio Grande Valley
Colorado,
United States
3.6 x 3 x .6 CM (miniature)
price: $50
new june 17
A simple single crystal of Barite with a dark phantom zone. This also has a druse of tiny sparkling Barites that add a little flash. In good condition and a nice example of the find.
A choice and attractive Tsumeb specimen. A flower-like cluster of sharp Malachite pseudo after Azurite crystals is nicely perched on mounds of sharp well crystallized green Duftite. These are sizable (for the specie) and they are perched on what looks to be Mimetite and some Cerussite with a few gem clear Calcite crystals, a tuft of Rosasite and a few other micros of related species. This is the kind of elegant and complex mixing of diverse species and crazy chemistry that makes Tsumeb minerals so incredible. In fine condition, displays well and a real treat under the microscope.
Prehnite - Single euhedral crystal
stock #17.1-316
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec,
Canada
2.1 x 1.3 x 1.4 CM (thumbnail)
price: $180
new june 17
A large, sharp, very pale green single crystal of Prehnite in blocky form. From the Jeffrey Mine, where some of the worlds best and largest Prehnite crystals were found. No damage and with good luster this is a nice thumbnail that shows the habit well. Prehnite is a rather common mineral but crystals over a half centimeter are very rare and only come from a few finds.
A complete floater, this twinned Cerussite is crystallized all around and is in pristine condition. Dusted with Micro crystals of Posnjakite and perhaps a few other species, which add a nice color contrast. The individual arms are complex, multi-faced, parallel growth crystals which are lustrous and in some areas transparent. Text book habit with the twinning well defined and esthetic.
Amethyst -
stock #15.1-520
Boekenhoutshoek, Mkobola
Mpumalanga,
South Africa
7.3 x 5.6 x 4.2 CM (cabinet)
price: $290
new june 17
From the find 3 years ago in the almost unpronounceable locale of Boekenhoutshoek, Mkobola. This is the sought after deep purple color that has not been found in more recent digging there. This small cabinet piece has excellent form and color. "Cactus" habit quartz are usually much more pale or are not even purple. The royal purple this piece has is the most uncommon and most desired. In fine undamaged condition,
Cerussite -vintage from classic locale

Freidrichssegagen Mine, Frucht, Bad Ems District
Rhineland-Palatinate,
Germany
3.2 x 2.6 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $380
new june 17
An old, very gemmy Cerussite with several different crystal habits present with label from the mining Acadamy at Freiberg (Bergakademie Freiberg). The Bad Ems area once had many lead mines and was famed for its great Pyromorphites. The Cerussites could also be quite fine as seen here but many old pieces do not have a clear mine atribution. This piece is clearly noted as from the Friedrichsegen mine, which closed in 1913. The condition is excellent.

An esthetic cluster of well formed leaf-like pink Serandite with contrasting white Analcime crystals. A classic association from Mt St Hillaire, the only locale where sizable, fine crystals were found. Minor black Aegirine is also noted. A lot of visual impact for a small specimen. In excellent condition.
