The best USA magnetites are these unique cubic crystals. Good ones are not common. This example has lusterous and fine crystals that reach 1.4 CM. Displayable from several sides, one face has a contrasting Talc that sets off the dark Magnetite well. Far better than average condition, but with damage at the outer edges and contacts/chipping can be seen. Since the magnetite here is exceptionally fragile, this degree of damage is actually very minimal, and the piece is a fine example of a rare form and a classic occurance. Ex. Ernie Schlicter, 1970's vintage.
SOLD Quartz v. Herkimer Diamond
stock #SOLD 7FE-174
Hickory Hill, Fonda, Mohawk township, Montgomery Co.
3.3 x 2.1 CM (small miniature/ large thumbnail (toenail))
Gemmy, air clear, sharp and perfect. This is what makes Herkimers so desirable! This is an especially esthetic toenail size and has everything one looks for in one of these. While Herkimer quartz is not rare, perfect examples like this are quite uncommon. From the Hickory Hill locality in Fonda, this is exceptional for that site.
Cuprite and Copper
Bisbee, warren District, Mule Mts., Cochise Co.
6.6 x 4 CM (cabinet)
A beautiful, scuptural specimen of well developed Cuprite decorating branching native copper. The Cuprite has excellent fresh red color and shows both single octahedra and flattened elongated octahedra in chains to over 2.5 CM. Individual crystals show bright glassy faces and the whole has a super esthetic form. Bisbee Cuprites are rarely this attractive.
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 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.
Calcite (frosted) on Quartz
Rossie Lead Mine, St. Lawrence Co.
4.8 x 4 CM (miniature)
From the classic old locality of Rossie that was active from 1830 to 1860. A nicely frosted main crystal with a few smaller on the sides sits on a quartz matrix. No damage. good clarity and some internal rainbows . This seems to be an untwinned crystal that was less common at Rossie. Calcites from here were used in many crystalographic illustrations and studies in the classic literature. These are rarely available now.
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!
