stock #Alec-35-034
Calvin Mitchell Prospect, Dekalb, St Lawrence County
New York, United States
5.7 x 4.7 x 4.5 CM (cabinet)
price: $320
Pre Holiday 2017

A spray of gemmy green Diopside crystals (to 1.4 CM) stand on a matrix of Quartz from famed Dekalb, NY locale. The Diopsides are undamaged and glassy, terminated and a few show fibrous areas inside. Not often available and usually quite expensive.
Rosasite on Malachite ps. after Azurite crystals
stock #17.1-697
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.6 x 2.6 x 2.4 CM (thumbnail)
price: $550
Pre Holiday 2017

One of the more famed Pseudomorphs from Tsumeb is Rosasite replacing Malachite that has replaces Azurite crystals. This is an excellent example with a thin outer zone of Rosasite that has several small Calcite rhombs sprinkled on the surface. Attractive and now quite uncommon, the main crystal is in perfect condition. Other crystals on the back and bottom side are broken showing the malachite core, does not affect display. A big thumbnail with a lot of good visual impact.
Fluorite in Dolomite cast
stock #17.1-696-17a
Walworth Quarry - Walworth, Wayne County
New York, United States
3.1 x 2.8 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $160
Pre Holiday 2017

A single gem-clear cube of Walworth Fluorite is perched perfectly inside a thin Dolomite cast. Walworth Fluorites are classic but not often available as few are found each year. This is even more unusual as the thin shell or "cup" is an uncommon matrix composed of tiny Dolomte crystals. The Fluorite is clean, undamaged and colorless. This could trim to thumbnail size if desired.
Pyrargyrite on Quartz with Dolomite, Pyrite, Galena etc.
stock #15.1-920-(SM5320)
Guanajuato, Municipio de Guanajuato
Guanajuato, Mexico
4.5 x 3.2 x 2.8 CM (miniature)
price: $300
Pre Holiday 2017

Clusters of dark ruby silver crystals with very good form stand out well from the contrasting matrix. In fine condition this could trim out to thumbnail size if desired but it looks fine as is. Ex Charles M. Noll collection, these crystals are quite dark as is typical at this region, and not translucent but in strong light shows bits of red color.
Fluorite on Lollingite
stock #A-11-017
Huanggang Mine, Chifeng Prefecture
Inner Mongolia Region, China
3.6 x 3.2 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $280
Pre Holiday 2017

Well-formed transparent Fluorite on crystalline blades of Lollingite in an attractive arrangement. A fine example from the Inner Mongolian finds at the Huanggang Mine. The display surface is perfect and undamaged, the back of the Fluorite has a clean geometric contact but is undamaged. The Lollingite from here is certainly some of the best ever found, the addition of fine Fluorite makes this miniature especially attractive.
Silver- Spinel twin crystals, wires etc
stock #17.1-362
Beaver Mine, Cobalt, Timiskaming District
Ontario, Canada
7.9 x 6.5 x 5.4 (cabinet)
price: $480
Pre Holiday 2017

A very rich, well crystallized and nearly pure Silver specimen. Like a sandwich the matrix forms the "bread" holding a fat 3.3 CM thick vein of silver. Crystals and wires protrude from the mass up to 2.5 CM and distinct Spinel twins reach up to 1.7CM. Nice patina and form. The bottom edge (as I see it)is flat where it was sawn or cut from matrix, otherwise this is perfectly natural and undamaged. From the collection of Les Hitchings, obtained by trade in 1968. His notes attribute this to Beaver mine which seems right for the habits and form but the label is not really clear on this attribution. A rich and choice old Silver from Cobalt no matter which mine.
Cerussite on Barite
stock #A-12-481
Mibladen Mine, Upper Moulouya lead district, Midelt, Khenifra Province
Meknes-Tafilalet Region, Morocco
4.9 x 3.4 x 2.4 CM (miniature)
price: $135
Pre Holiday 2017

One of the best values in todays mineral market are the Cerussites on orange Barite from Mibladen. This is a especially fine example with no damage, transparent and complete Cerussite crystals and a nice composition. Compared with a similar Cerussite from any other locale, these are super inexpensive and a good value. This specimen is quite above average with no issues or detractions.
