Enargite -Classic locale
stock #16.1-601
Leonard Mine, 3800 foot level, Butte
Montana, United States
5.2 x 4.8 x 3.9 CM (small cabinet/ large miniature)
price: $380


A cluster of unusually bright, lustrous and sharp Enargite crystals with a few small Pyrite and Quartz on the edges. In excellent undamaged condition with Enargites free standing up to 1.7 CM. A choice, classic Leonard Mine (Butte, Montana) specimen from the golden age of mining there. The flashy luster on this black Copper Sulphide is quite esthetic (and even attractive for a black mineral)compared with the more usual sooty black specimens.
Fluorite -classic zoned Illinois
stock #9.1-095
Rosiclare level, Minerva Mine #1, Minerva Oil Co, Cave-in-Rock district
Illinois, United States
7.8 x 5.8 x 3.9 CM (cabinet)
price: $575


A choice old Minerva mine specimen with strong purple to yellow zoning. In very fine condition and with wonderful details of stepping and complex face planes. The photos have a little backlight to show the color and zoning with stronger backlight they are far more dramatic, brighter and intense but not typical of a normal display. Without any backlighting the zoning is visible but subtle. A few tiny Chalcopyrites are evident too.
Aurichalcite with Hemimorphite
stock #18.1-746
79 Mine, Hayden, Banner District, Gila County
Arizona, United States
4.7 x 4 x 3.8 CM (miniature)
price: $1100
Dec 2018

An outstanding Copper specondary specimen, a miniature Aurichalcite from the famed 79 Mine. The condition is exceptional and the display impact is also top notch. Some of the best Aurichalcites ever found came from this small mine years ago but are not often available in this quality. In incredible undamaged condition, remarkable for such a delicate specimen. A few small clear balls of radiating Hemimorphites add a nice contrast too. Brilliant color and luster give this a great display impact much bigger than the size. Really far better in person.
Smithsonite- classic
stock #17.1-583
Kelly Mine, Magdalena
New Mexico, United States
5.6 x 5.3 x 3.3 CM (cabinet)
price: $475
Dec 2018

Kelly Mine Smithsonite with the most desirable wet look luster and good blue color. Ex Hitchings collection this is in fine condition a few of the outer edges show where this was removed but all the display surface is perfect clean and undamaged. A few areas of the white mottling are present which adds a nice contrast. This is a pre 1970 specimen. These have become American classics and there is no other Smithsonite worldwide that has just this look, color and luster.
Autunite
stock #17.1-551
Daybreak Mine, Spokane County
Washington, United States
5.5 x 4.2 x 2.2 CM (cabinet)
price: $475
Dec 2018

A fully crystallized plate of Autunite from the old sixties vintage finds at the Daybreak Mine. Now considered American classics, this piece has been stabilized to keep it from crumbling as many did. As the Autunite looses water in dry air they tended to alter to Meta Autunite and fall apart. Vivid fluorescence as was typical for these, this specimen came from the Les Hitchings collection, obtained in 1970. Good color and form in excellent condition.
Sphalerite on Quartz
stock #18.1-625
Clinton, Onieda County
New York, United States
3.5 x 2.7 x 2 CM (small miniature/ large thumbnail (toenail))
price: $110
Dec 2018

A bright lustrous Sphalerite crystal perched above a sparkling Quartz matrix. From an important 1987 find in Clinton, NY. this is an excellent clean example. The Sphalerite shows the complex form that is typical with multiple twinning and is translucent, light passing through gives a rich yellow to rootbeer color. Can be trimmed to a thumbnail if desired. A modern classic from the Northeastern USA not often available.
Smoky Quartz on Microcline (Amazonite)
stock #18.1-611
Government Pit, Albany, Carrol County
New Hampshire, United States
4.7 x 3.8 x 3 CM (miniature)
price: $240
Dec 2018

A neat miniature hosting a fine Dauphine twin Quartz that has gem clear transparency. A New England classic, these are often compared with the well-known Colorado specimens but are quite different in person. the matrix is well crystallized Amazonite, with the blue green color most desirable from New Hampshire. Ex Ernie Schlichter collection, this was collected by him in the heyday of the Government pit digging. The luster is excellent and glassy on the Quartz and a pleasant matte finish on the Feldspars making a nice contrast. These are from an old stash and are not at all common on the market
Calcite- gemmy, twinned
stock #15.1-513
Elmwood Mine, Carthage
Tennessee, United States
5.4 x 5 x 2.3 CM (cabinet)
price: $360
Dec 2018

Ultra clear, a pair of transparent crystals of twinned Scalenohedral Calcite from the great Elmwood mine. The faces are glassy and the termination tips show a slight hint of a cognac color otherwise these are perfectly colorless. The twinning is both a rotational and interpenetrated type, which is very easy to see in person. Just a hint of matrix is present, mostly on the backside of one crystal. The condition is fine and the terminations are uncleaved, A contact on the back, lower edge is noted but no damage. Now that the Elmwood is closed probably forever, good, clean Calcites of the quality are becoming quite uncommon and prized.
