21470:
Galena and Sphalerite - $16
Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria
Miniature - 5.7 x 3.7 x 2.1 cm (2.2 x 1.5 x 0.8 inches)
Specimen status: Available     Send email to order

The galena crystals on this specimen are almost all simple cubes, which reach about 8 mm. These are accented by scattered, smaller but sparkly, black sphalerites. Minor quartz also noted. Sits well for display on a naturally flat base. Minor, scattered chips and cleaves do not distract.







21472:
Galena - $26
Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria
Cabinet - 6.7 x 4.4 x 4.1 cm (2.6 x 1.7 x 1.6 inches)
Specimen status: Available     Send email to order

A cluster of dark galena crystals, with individual crystals reaching 2.2 cm. Minor dark green, lustrous sphalerites also present. No damage, and plenty of stand-independent display angles.







21498:
Vivianite - $14
Tomokoni Mine, Machacamarca District, Cornelio Saavedra Province, Potosí Department, Bolivia
Miniature - 4.5 x 1.7 x 1.3 cm (1.8 x 0.7 x 0.5 inches)
Specimen status: Available     Send email to order

A deep green (not blue as the photos suggest), opaque to transparent vivianite crystal. The ends appear contacted (not broken) as if the crystal grew across a cavity. Tomokoni Mine vivianites were once rather abundant but are now uncommon. Many have turned black and split apart, as their Fe2+ has air-oxidized to Fe3+ over time. This is probably why this crystal appears dark blue (on the surface) but in fact is a pleasant Coke bottle green under transmitted light. Cleaved along one face.




21549:
Topaz
Minas Gerais, Brazil
Miniature - 4.9 x 3.9 x 3.2 cm (1.9 x 1.5 x 1.3 inches)
Specimen status: Sold

A colorless and mostly transparent topaz crystal, with many naturally etched, silky regions. Although not enough of the original crystal faces remain to allow visual identification, that this is topaz is clear from its density. Has many natural display angles that do not require a stand. No damage.







21644:
Spessartine and Opal-AN - $100
Wushan Spessartine Mine, Tongbei, Yunxiao County, Zhangzhou Prefecture, Fujian Province, China
Large cabinet - 12.4 x 9.8 x 4.8 cm (4.9 x 3.9 x 1.9 inches)
Specimen status: Available     Send email to order

The display face is completely covered with a rich carpet of orange-brown, mostly translucent to transparent spessartine garnet crystals. Individual crystals reach about 4 mm. The very top knob (first picture) has a small patch of opal-AN (hyalite), which fluoresces a bright green under both longwave and shortwave UV. Sits perfectly for display as shown the first picture without needed a stand. No damage.




21645:
Azurite and Malachite - $125
Bisbee, Warren District, Cochise County, Arizona
Large cabinet - 11.9 x 8.8 x 1.8 cm (4.7 x 3.5 x 0.7 inches)
Specimen status: Available     Send email to order

A flat gossan matrix plate hosts hundreds of deep blue, sparkling azurite crystals, which reach perhaps 3 mm. Minor malachite tufts scattered about. Lots of terrain to explore with a hand lens or camera lens. No damage.







21788:
Calcite pseudomorph after Aragonite
Las Animas, Bent County, Colorado
Miniature - 3.2 x 2.8 x 1.2 cm (1.3 x 1.1 x 0.5 inches)
Specimen status: Sold

A sharp, hexagonal pseudomorph of calcite after aragonite. The red spots are bits of the red clay in which these classic pseudomorphs form. No damage.




21816:
Barite and Fluorite - $12
Rock Candy Mine, Grand Forks, Greenwood Mining Division, British Columbia, Canada
Miniature - 3.3 x 3.0 x 1.6 cm (1.3 x 1.2 x 0.6 inches)
Specimen status: Available     Send email to order

A core of colorless fluorite hosts several yellow, mostly transparent, block barite crystals reaching 1.2 cm. These are accented by a carpet of lavender fluorite 'dust'. Scattered cleaves and chips are noted on this small miniature, but these do not detract at this price. Sits nicely on its naturally flat base.




21818:
Calcite - $10
Ohio
Cabinet - 6.1 x 3.5 x 3.1 cm (2.6 x 1.4 x 1.2 inches)
Specimen status: Available     Send email to order

A sharp, doubly-terminated, translucent, amber-colored calcite crystal sits nicely on a flat matrix slab (which provides an excellent natural display base). No damage. Probably from the Pugh Quarry.







22029:
Cylindrite
Santa Cruz Mine, Poopó, Poopó Province, Oruro Department, Bolivia - Type locality for cylindrite
Miniature - 5.6 x 3.5 x 2.7 cm (2.2 x 1.4 x 1.1 inches)
Specimen status: Sold

Several faces of the massive gray matrix host thin, elongated cylindrite crystals to about 1 cm in length. Cylindrite is an uncommon iron tin lead sulfosalt, Pb3Sn4FeSb2S14, named for the cylindrical crystal morphology. The Santa Cruz Mine is the type locality.







22097:
Vanadinite and Barite - $16
Mibladen Mining District, Midelt Province, Drâa-Tafilalet Region, Morocco
Miniature - 5.0 x 4.4 x 3.3 cm (2.0 x 1.7 x 1.3 inches)
Specimen status: Available     Send email to order

A mound off dirty white, translucent to opaque barite blades hosts a covering of red-brown to brown, translucent to opaque vanadinite crystals. Individual vanadinites reach almost 5 mm, and the majority are complete. There are even vanadinites on the backside of the matrix and barite, in an area where it appears the specimen detached from its original matrix before more vanadinite grew in.







23029:
Calcite and Quartz - $24
Nasik District, Maharashtra, India
Miniature - 5.8 x 5.2 x 5.0 cm (2.3 x 2.0 x 2.0 inches)
Specimen status: Available     Send email to order

A honey-brown, translucent calcite scalenohedron is partially coated by opaque, white chalcedony, like an avalanche flowing down the side of a mountain. A cluster of colorless quartz points lie at the base of the calcite, 'threatened' by the avalanche. Sits well for display on its cleaved base. A small cleave near the peak on the backside of the mountain is obscured when displayed as shown.
