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 well formed thumbnail of complex Acanthite crystals. These show modified cube forms and "melted" look hoppered crystals. A nice dark silver patina and good luster give this a nice presence. A classic Mexican specimen.

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.
A super well formed snowflake style Cerussite twin with excellent detail and luster. A textbook perfect habit in remarkable clean condition damagewise this displays great from several angles. Presents both gemmy transparent areas and zones of "catseye" inclusions. Fine classic material and better in person.
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.
A cute small miniature featuring glass clear cubes that are almost colorless but have a tiny hint of blue in some light. The main Fluorite is 1.3 CM across and there is no damage on the specimen. The matrix can be seen perfectly through the crystals. Walworth Fluorites are quite rare on the market and much respected by regional collectors and Fluorite lovers worldwide. From an older collection this is a very good value.
Thumbnail specimen of gemmy Eosphorite crystals in a radiating spray on Quartz matrix. As is sometimes the case there are micro crystals of Zanazzite associated. The condition is excellent and by naked eye perfect. At 20X magnification one small crystal can be found that has some termination damage. Remarkable for this delicate mineral in such long, slender crystals. great value.
A sculptural arrangement of elongated crystals of Apophyllite with green inclusions and some zoning due to Celedonite inclusions. In fine condition and with great form this stands out among the many average pieces from the famed Deccan traps of India. As fine minerals from many locales have become so incredibly expensive, it is still possible to build a suite of top notch Indian minerals for a relatively modest investment.
