Cassiterite variety Needle Tin
Minera Monserrat, Challapampa, Poopo Province
5.6 x 5.5 x 3.4 CM (cabinet)
A very unusual specimen from Boliva that looks like an old Cornish "needle tin". A three dimensional matrix densely covered with delicate accicular crystals of brown Cassiterite. In fine condition as seen, ex. Hitchings collection. Especially impressive under magnification, this is an uncommon habit and a well crystallized example.
Choix, Municipio de Choix
4.3 x 3.8 x 1.7 CM (miniature)
Bright pink Smithsonite in a bubbly habit with no adhering matrix. Fine color and luster in an attractive shell-like cast structure. From the long known prospects at Choix, Simaloa, Mexico. Sadly this locality has had many problems and has stopped producing due to cartel violence. The bright colored Smithsonites from here are now highly regarded as fine specimens.
Hohenstein Massif, Omaruru District
2.3 x 1.8 x 1.5CM (thumbnail)
Brilliant gemmy green Fluorite thumbnail, with intergrown cubo-octahedral crystals on Muscovite. In fine condition as seen, from a small recent (2017) pocket on Hohenstein. Not typical at all, a fine thumb!
Red Quartz with Fluorite
Orange River, Namakwa
Northern Cape Province,
3.1 x 1 x .9 CM (small miniature/ large thumbnail (toenail))
An outstanding thumbnail of bright red quartz (included by Hematite) that is decorated with deep purple cubes of Fluorite. Eyecatching esthetics and strong color the Quartz is in excellent condition showing some zoning and no damage. 20 X magnification finds a few micro rough areas on the Fluorites but that is not seen by naked eye. Choice and very unusual. From a small find a few years ago in the Orange River near the Namibian Border.
A gem clear single crystal with excellent dark green to bluish color, and glass-like luster. Sharp and elegant, this is at its best with some backlight to bring out the inner colors. On the backside some small matrix is adhering, but mostly this is a single, loose crystal. Typical curving of the termination can be seen at some angles. Choice older specimen from 1980 vintage finds, excellent condition.
Rhodochrosite -rare Colorado locale
Idaho Springs, Clear Creek County
3 x 2.8 x 1.5 CM (small miniature/ large thumbnail (toenail))
A single rhomb crystal with fine deep red color from a 1960 find in Idaho Springs. Similar to the better know localities of Sweet Home (Alma) and American tunnel (Silverton this came from an unidentified mine (likely the Moose mine or any of several Central city sites). The collectors were the Hitchings (father and son team) on a family trip from Massachusetts to Colorado. They collected 7 specimens from a boulder in a dump, this being the largest rhomb. They were not sure of the mine name and recorded these only as Idaho Springs.
Simply a killer with perfect form, zoned crystals are arranged in a radiating cluster. These three species are found together as zoned sections of individual crystals at this site. This find at Huanggang (Inner Mongolia) have redefined these species and are widely regarded as the worlds best. The tips of these crystals are translucent and show some internal zoning but the overall display quality of this piece is why this is so exceptional. Helvite and Genthelvite are fairly rare but known from several locales. However good Danalite is ultra rare worldwide these rank as world class crystals.
A classic and fine old specimen of the Adularia variety Valencianite. Ex Harvard University, Ken Hollman and Terry Szenics collections. From the Valenciana Mine(Guanajuato, Mexico) this has sizable crystals to 2.7 CM,and is in perfect undamaged condition. A dusting of small clear Quartz crystals and a few micro Sulfides ads some character as well.
