Grand Reef Mine - Graham County
4.1 x 2.9 x 1.8 CM (miniature)
A miniature from the Grand Reef Mine hosting milky white Cerussites with the habit that looks much like a doubly terminated Quartz. The Cerussites are on a typical druzy Quartz matrix and are in very good condition. A nice locality piece, the Grand Reef Mine is well respected as a source of some uncommon Lead secondary minerals.
2.7 x 1.5 x .5 CM (thumbnail)
A crystalized thumbnail of Cornish Torbernite with a bright apple-green color. Ex Dr T.B. Wilson collection, we do not have a mine attribution for this piece although it looks like a great match to Old Gunnislake Mine, but that is not documented. There are many Torbernite locales listed in Cornwall, most have crude plates or scattered crystals, relatively few have rosettes and dense clusters. A colorful English piece that is reasonable in cost yet choice.
Olesna, Horovice, Beroun District
Central Bohemia Region,
7.1 x 6 x 4.4 CM (cabinet)
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
Devils Den, Mount Tabor, Rutland County
3.8 x 3 x 1.1 CM (miniature)
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.
Hematite PS after Marcasite
White Desert, Farafra Oasis
New Valley Governorate,
2.9 x 2.8 x 2.7 CM (small miniature/ large thumbnail (toenail))
A perfect complete radiating pseudomorph with super form. I consider these Pseudomorphs from Egypt some of the best values in minerals today. They are sporadically available on the market and sometimes (as in this piece ) have a highly esthetic form. This shows perfectly well the original crystal structures. A choice example, no damage or contacts.
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province,
3.8 x 3.4 x 2.2 CM (small miniature/ large thumbnail (toenail))
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.
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.
Sierra de la Cruz, Municipio de Sierra Mojada
7.3 x 6 x 3.7 CM (cabinet)
Blocky habit Vesuvianite crystals that are doubly terminated are studding a contrasting Rhyolite matrix. From very old finds at the locality once called Lago de Jaco, now Sierra de la Cruz. The Vesuvianites are well exposed from the matrix and are nearly all bi color. This habit of Vesuvianite was collected before 1980, there have been no more in recent years.
