Fluorite w. Quartz
stock #ALEC-32-233
Cantera Llamas, Duyos, Caravia
Asturias, Spain
2.5 x 2.3 x 1.8 CM (thumbnail)
price: $130
Fall 2015

Simple cube of transparent Fluorite with modified edges with a small matrix of Quartz. Pale color and some internal clouding but as seen a nice example of the find at Llamas Quarry in quite good condition. Small natural contacts as seen and a cleave on the bottom where removed that is not seen on display. Better in person too.
Calcite on Quartz fingers
stock #ALEC-15-285
Banpo Mine - Dushan Co., Qiannan Aut. Pref.
Guizhou, China
5.6 x 4.7 x 4.4 CM (cabinet)
price: $280
Fall 2015

Green Calcite in flattened disk-like crystals are perched on slender fingers of Quartz. When these were found the color was attributed to copper salts in the calcite, this was never confirmed though it is likely. An older specimen obtained in 2002 at the mine and formerly in the Shields Flynn collection. A very good example in fine condition from the one time discovery.
Vesuvianite
stock #15.1-319
Jeffrey Mine, Asbestos
Quebec, Canada
3.6 x 3 x 1.6 CM (miniature)
price: $280
Fall 2015

A colorful, bright and fine small miniature of glasslike Vesuvianites from the Jeffrey Mine. The color, luster and esthetics are excellent. This quality in a cabinet specimen would be several thousand dollars. Some areas of contact are noted with magnification and some old recrystallized breaks as well. All the main crystals are pristine and undamaged. Better in person
Pyromorphite
stock #15.1-565
Broken Hill, Yancowinna County
New South Wales, Australia
4.3 x 3.2 x 2.8 CM (miniature)
price: $160
Fall 2015

Transparent Pyromorphite crystals scattered on a contrasting dark matrix from Broken Hill. The dark matrix is often labeled as Coronadite but this is not confirmed in this specimen. Most crystals are pristine but some damaged or broken prisms are seen with magnification. Pyros about 5mm, bright green-yellow hue from a classic locale.
Fluorite on Quartz
stock #ALEC-32-232
Cantera Llamas, Duyos, Caravia
Asturias, Spain
3.8 x 3.3 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $140
Fall 2015

Small but elegant miniature with a "cityscape" form with gem clear small Fluorite cubes perched on the "towers". This could be trimmed to thumbnail if desired but I like it as is. In exceptional undamaged condition and quite differnt from most specimens from this small but outstanding locale.
Beryl var. Emerald in Schist
stock #17.1-AL-12-379
Tokovaya River, Malyshevo Ekaterinburgskaya Oblast
Urals Region, Russia
7.5 x 4 x 3.8 CM (cabinet)
price: $750
Fall 2015

A classic old Russian Emerald specimen with a sizable (2.7 CM) terminated prism that is well exposed on its schist matrix. The crystal is quite transparent with a few inclusions. Some additional Beryl crystals are also on the matrix. We have photographed this with "normal" display lighting, if it is backlit it displays with clarity.
Arsenbrakenbuschite with prismatic Mimetite, Tsumcorite? and Descloizite
stock #13.1-040
Mina Ojuela, Mapimi
Durango, Mexico
8.8 x 6.5 x 3.9 CM (cabinet)
price: $320
Fall 2015

Cabinet specimen well crystallized with many prismatic gemmy hexagons of Mimetite to about 8MM that are set on and mixed with yellow to orange tufts of Arsenbrackenbuschite. The prisms of Mimetite are a more rare habit at Ojuela. There is also what seems a perfect match for Tsumcorite (which has also been found in this assemblage), but this was not tested. A few Mimetites have some damage (not seen by my naked eye) but most are perfect with a yellowish to transparent grey color. This would make many thumbnails and micro specimens if split up. As is, a rich cabinet specimen for these rare minerals.
Bismuthinite inside Fluorite on Arsenopyrite
stock #Alec-15-243
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.2 x 3.2 x 2.5 CM (miniature)
price: $285
Fall 2015

A attractive miniature with a prominent Fluorite cube that is densely filled with needles, hairs and curls of metallic Bismuthinite. Since the Fluorite rests on a well crystallized cluster of Arsenopyrite, the overall contrast and esthetic structure is excellent. As with many fine Yaogangxian specimens, there are many associated species, this has Sphalerite, Stannite and Quartz. Better in person, this is an older specimen from the Shields Flynn collection.
