SOLD Chalcopyrite on Calcite
stock #SOLD 18-AX-19-085B
Brushy Creek Mine, Greely, Viburnum Trend District, Reynolds County
Missouri, United States
7.8 x 4.7 x 5.1 CM (cabinet)
price: $0
Late Summer 2018

A series of sharp scalenohedral Calcite crystals are epitaxially coated with bright sparkling Chalcopyrite. A pretty and affordable Brushy Creek specimen that shows very well the form and color contrast that has made this a famous habit. Some minor cleaves but overall in good condition as seen. Sharp form and very good color contrast with some iridescence as well.
SOLD Smithsonite - Cadmium, Classic Irish
stock #SOLD 18-AX-12-441
Sheshodonnel East Mine, Carron, the Burren
County Clare, Ireland
5.7 x 3.8 x 2.4 CM (small cabinet/large miniature)
price: $0
Late Summer 2018

Brilliant Cadmium yellow color Smithsonite from this very small, ancient mine. Worked only from 1862-1863, this held a colorful vein of Smithsonite that was waste rock at the time but today are prized as one of the few true Cadmium Smithsonites. Ex Lindsay Greenback (an old secured minerals label is included) specimen, this has good luster and the rich color that is the most desirable. A few bruises mostly on the edges but in reasonable condition overall as seen. There are fluorescent zones as well, these are not very often available and this has color better than most.
Barite (Barytes) - dark blue
stock #18.1-431
Paga mine, Cartersville District, Bartow County
Georgia, United States
4.8 x 3.1 x 2.2 CM (miniature)
price: $220
Late Summer 2018

A deep blue chisel-tip Barite from the now classic Georgia (USA) locale at Cartersville. The deep "royal blue" color was the most desirable but very uncommon at this locale. This is a choice miniature example in fine condition, with good transparency, luster and very sharp terminations. Not often available anymore, a good Georgia Blue is a welcome addition for any suite of Barite and especially for a Southeastern USA collection.
stock #18-AX-7-187 (409)
Graves Mt., Lincoln Co.
Georgia, United States
4.3 x 3.2 x 2.6 CM (miniature)
price: $180
Late Summer 2018

This is the termination section of a complex Rutile crystal that shows twinning. From the famed Graves Mountain locale, which is among the few localities worldwide that produced such large, blocky habit Rutile. Textbook form, undamaged and quite sharp for one of these, the color is a very dark red brown. No damage on any of the display sides, cleaved on the base (bottom) only.
Fluorite on Quartz
stock #18-AX-20-230
La Viesca Mine, Huergo, La Collada, Siero
Asturias, Spain
6.6 x 4.1 x 3.8 CM (cabinet)
price: $260
Late Summer 2018

A multi-color phantom Fluorite nicely perched on a sculptural matrix covered with druzy Quartz crystals. Excellent transparency and in fine condition, there are a few additional Fluorites on the specimen one of which is a slender, highly elongated cube. A classic European locale, the La Viesca Mine is famed for vibrant color varieties and general quality of its Fluorites. This one is a bit unusual but still has the look and style well known from this venerable locality.
Chrysocolla (Druzy overgrowth of Quartz)
stock #18.1-432
Inca De Oro, Chanaral
Atacama Region, Chile
2.7 x 2.5 x 1.6 CM (thumbnail)
price: $110
Late Summer 2018

Bright sparkling blue Chrysocolla thumbnail with very pretty form. Druzy Chrysocolla is found sporadically in small amounts at just a handful of locations worldwide, and the electric color has made it highly desirable for lapidary as well as an esthetic, collectable mineral. The matrix of this piece is a solid dark gossan that has a scalloped surface. The Chrysocolla in this case is likely a pseudomorph of earlier Malachite crystals. Displays well with more impact that usual for the size.
Descloizite -unusual form, iridescent
stock #18.AX-12-055
Berg Aukus, Grootfontein District
Otjozondjupa Region, Namibia
5.5 x 4.3 x 2.6 CM (small cabinet/ large miniature)
price: $190
Late Summer 2018

There are many different habits seen in the Descoizites of Berg Aukus, which is certainly the premier locale for this mineral. This specimen has a rounded series of crystal aggregates that present curved faces and a colorful patina. The iridescence is most striking and at first glance this looks like a fine Chalcocite. Undamaged, pristine condition, and crystalized all around, the underside is a hollow cup holding more traditional forms of small bright red Descloizite crystals. We have handled and seen many fine Berg Aukus specimens but this piece is unique in my experience. Ex William Hladysz collection, his catalog notes "very rare habit, unlike any other".
Chrysocolla - drusy Quartz overgrowths
stock #18.1-433
Inca De Oro, Chanaral
Atacama Region, Chile
4 x 2.6 x 1.7 CM (miniature)
price: $280
Late Summer 2018

Super bright color and sparkling luster, this has a tiny bit of Malachite remaining but most all is pure Chrysocolla. The Chrysocolla shows the elongated forms of primary Malachite crystals which it has replaced. The brilliant blue fingers on this piece are radiating outward from a Gossan matrix and are fully encased with clear, sparkling Quartz. Fine and delicate, in excellent condition and with strong display impact.
