Central Bohemia Region,
Czech Republic
7.1 x 6 x 4.4 CM (cabinet)
price: $40
A black ugly, nearly pure, globular Lithiophorite that is a very good example of the specie and the locality. From an old Czech collection, this Manganese Oxide mineral (with Aluminum and Lithium) is never a "pretty" mineral, but it is uncommon and this a rich specimen.
Quartz- faden, USA locality
stock #19.1-365
Devils Den, Mount Tabor, Rutland County
Vermont,
United States
3.8 x 3 x 1.1 CM (miniature)
price: $85
The faden Quartz from the long known locality of Devils Den, Mt Tabor, Vermont is rarely seen. This site was recently described in the June, 2019 issue of Rocks and Minerals, and illustrates several unusual habits of Alpine style Quartz not often seen in the USA. This tabular transparent Quartz crystal shows a very distinct faden string as well as offset growth structures and recrystallized breaks. Some chipping exists at one end but the rest is undamaged. A nice gemmy transparent Faden from the USA not often available.
Olmiite

3.8 x 3.4 x 2.2 CM (small miniature/ large thumbnail (toenail))
price: $90
Spring 2019
A cute specimen of Olmiite crystals in spherical form on contrasting matrix. Nice luster and fair pink color, these were once all labeled as Poldervartites (a rare mineral at the time of the find) later re-studied and classified as Olmiite (also at that time a rare mineral). This discovery was sizable and enough good specimens found to allow collectors to own a nice piece without major financial pain. In good condition and a good value.
Analcime on Serandite/ Schiziolte
stock #18.1-744
Mont Saint-Hilaire, Monteregie
Quebec,
Canada
2.7 x 1.7 x 1.1 (thumbnail)
price: $65
Classic Mt. St. Hillaire specimen of a cream Analcime crystal nicely perched on a salmon color Serandite and or Schiziolite cluster. The Serandite is broken at one end but terminated (crudely) on the other. It has been recently determined that some but not all of this habit Serandite is in fact Schiziolite and requires testing. It seems that some crystals are also zoned and have both species present. This one has not be analyzed. As is typical on specimens from this locale, there are other species present as micro crystals too, a Polylithonite rosette and a small cluster of Rhodochrosite. Nice combo thumbnail.
