Chalcopyrite (skeletal Crystals) and Enstatite
stock #9.1-165
French Creek Mines, St Peters, Chester Co.
Pennsylvania, United States
4.5 x 3.2 CM (miniature)
price: $350


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.
Azurite, Malachite w. Minor Cuprite and unknown micro xls.
stock #9.1-164
Cole Shaft, Bisbee, Warren District, Mule Mts, Cochise County
Arizona, United States
8.3 x 5.5 CM (cabinet)
price: $500


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
stock #9.1-163
Rossie Lead Mine, St. Lawrence Co.
New York, United States
4.8 x 4 CM (miniature)
price: $250


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.
Vesuvianite and Mangoan-Vesuvianite
stock #9.1-160
Jeffrey Mine, Asbestos
Quebec, Canada
5.7 x 5.3 CM (small cabinet/large miniature)
price: $320


Outstanding example of the species and this closed locality. A brilliant, sparkling cluster of jewel like crystals that range from a few millimeteres up to 1.8 CM. The luster is excellent and crystals are gemmy. Esthetic and eyecatching, this is far better than average for this classic find. Very clean of damage and displays well from many angles. The color is more vivid and rich in person.
Sphalerite
stock #AC-017
Joplin Field, Tri State District, Jasper County
Missouri, United States
8.6 x 5.4 x 3.6 CM (cabinet)
price: $325


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!
Sphalerite (Cleiophane) with Galena
stock #9.1-154
Krushev Dol Mine, Madan, Rhodope Mts.
Plovdiv Oblast, Bulgaria
6.7 x 4.6 CM (cabinet)
price: $350


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)
stock #8.1-458
Cerro de Mercado, Victoria de Durango
Durango, Mexico
5.2 x 3.9 CM (miniature)
price: $145


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.
Tourmaline (Elbaite) in stacked prisms
stock #8.1-449
Golconda Pegmatite district, Governador Valadares, Doce Valley
Minas Gerais, Brazil
4.9 x 1.6 CM (miniature)
price: $425


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.
