Cerussite
stock #18.1-349
Grand Reef Mine - Graham County
Arizona, United States
4.1 x 2.9 x 1.8 CM (miniature)
price: $50


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.
Strengite with Leucophosphite etc.
stock #19.1-449
Teskov, Rokycany District
Pizen Region, Czech Republic
8.6 x 6.4 x 5 CM (cabinet)
price: $90


A large block of matrix with sizable surfaces densley covered with interesting Phosphates, mostly Strengite balls and Leucophosphite but others are also present. From the remarkable mine at Teskov that has been a fine source of Phosphates. Ex. Dr. Petra Choce collection, this could be turned into many thumbnails or micro specimens but as is it offers many esthetic views under magnification.
Torbernite
stock #15.1-453

Cornwall, England
2.7 x 1.5 x .5 CM (thumbnail)
price: $80


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.
Quartz- "prase" included by Hedenbergite
stock #19.1-084
Serifos Island, Cyclade Islands
South Aegean, Greece
5.5 x 3.1 x 1.7 (small cabinet/large miniature)
price: $90


A cute classic Greek "Prase" or "Prasm" Quartz with good green color, translucence and sharp tapering crystals. Serifos Quartz has been a long known and collectable variety, it has a very distinctive habit that is only known from a few other skarn deposits worldwide. These have become quite pricy on the market, this one is in good shape, has only very tiny chips that are hard to see by naked eye, and is very reasonably priced for one of these.
Lithiophorite
stock #19.1-373
Olesna, Horovice, Beroun District
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.
Hematite PS after Marcasite
stock #19.1-352
White Desert, Farafra Oasis
New Valley Governorate, Egypt
2.9 x 2.8 x 2.7 CM (small miniature/ large thumbnail (toenail))
price: $90


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.
Olmeite
stock #19.1-237
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
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.
