A pretty and quite esthetic classic from the John Marshall collection, previously in R. Graeme collection. Labels included list the exact locality as "141 F stope, 1200' (366M) level, Cole shaft." Sharp, undamaged and lusterous blue azurites to 1.3 CM in size scattered in a green vug about 5 CM across. Nice Bisbee material has become very expensive and much less common. A very good value.
A delicate and esthetic classic. The early French Creek Chalcos are distinctive and very much sought after, they are definately the most desired US chalcopyrites. The skeletal growth structures make very intricate geometric forms that are well presented here. The enstatite crystals reach 1.6 CM and are all terminated. These make a fine contrast and the overall presentaion is very fine.
A single modified octahedron (3 CM) of Fluorite set esthetically in a nest of Muscovite blades. The Fluorite has a slight frosting but is very clear internally and the color is especially unusual, being pinkish with an orange hue. At quick glance this can even look like a Scheelite. Overall in good condition, there are some rough areas from muscovite contacts as seen in the photos, they are not distracting. For any Fluorite or Pakistani suite, this is a very desirable addition.
Joplin Field, Tri State District, Jasper County
8.6 x 5.4 x 3.6 CM (cabinet)
A brilliant and pristine red Sphalerite from the classic Tri State district. Even though this was once easilly available it was not usually as attractive as this piece. The mines have been closed for decades now and is now quite uncommon to find any good USA "ruby jack". A sizable vug of 7.5 Cm across is packed with lusterous sparkling Ruby color crystals that reach 1.1 CM however most are smaller. No damage, great esthetics and all crystals are translucent. There are some saddle shape Dolomites and a sprinkling of Chalcopyrite as well for a nice contrast. The back of the matrix block has a nice display of Sphalerite as well (6 CM across), and would be an excellent piece on its own. Very classy color and great eye appeal as well as being an affordable classic US piece!
A big (2.9 CM) yellow-green Sphalerite compound crystal sits perfectly on a matrix of galena and some quartz.. Outstanding condition, this is rare older Madan material that is not often available.
Fluorapatite (Apatite CF)
Cerro de Mercado, Victoria de Durango
5.2 x 3.9 CM (miniature)
The Cerrro de Mercado apatites are a Mexican classic, and now its quite hard to find nice ones. I try to purchase any decent piece I see since I think these are still undervalued and destined to be good investments. These were once plentiful, although undamaged crystals and good matrix piece were never very common. This example is in very good condition and an esthetic matrix piece as well. The main 3.4 CM crystal is quite sharp, gemmy and is well placed on the matrix. The small specimen has good presence and glass like luster. There are a few other tiny crystals scattered about although some are damaged they are not visible from the display side.
A fine zoned green gem crystal with a remarkable and rare termination. This looks like a reversed scepter as the inner termination rises above the base prism. Very sharp and clean, there are some very tiny chips on a few edges but not distracting at all. Pretty much all gem with green color ranging from yellowish to a deeper bottle green color.
Tuokexun (Toksun) Tulufan Prefecture
Xinjiang, Uygur region,
6 x 4.8 x 3.8 CM (cabinet)
Rich deep orange color and glassy luster make this a very good eyecatcher. Crystals reach 2.4 CM in with many complete and well positioned. There is damage but in contect it is easy to overlook, yet it keeps this from a much higher price point.
