Tamminen Mine (Quarry), Greenwood, Oxford County
2 x 1.6 x 1.4 CM (thumbnail)
A thumbnail cluster of Hydroxylherderite crystals up to 1.6 CM in size. This specimen was collected in the mid sixties by Les Hitchings. The Waisanen Quarry is part of the legendary Oxford County, Maine pegmatite zone and is well known to local collectors but less so farther afield. The quarry has yielded some many rare minerals, many Phosphates and and occasional gem crystal but is best known for the Herderites. A nice thumbnail, these are not often available.
A very pure seam of good, dense green Chrysoprase with excellent translucency. Nearly all gem grade weighing over 96 Grams. From an older collection a 1966 vintage chunk.
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.
