16587:
Smithsonite - $10
Serpieri Mine, Lavrion District, Attikí Prefecture, Greece
Miniature - 4.2 x 3.4 x 2.7 cm (1.7 x 1.3 x 1.1 inches)
Specimen status: Available     Send email to order

Gray, very silky, botryoidal smithsonite on matrix. No damage.




16937:
Calcite - $40
Mexico
Large cabinet - 20 x 14 x 8 cm (8 x 5.5 x 3 inches)
Specimen status: Sold

A large, intricate calcite specimen, in which the crystals are mostly translucent, thin and platy. Their intergrowth makes it difficult to give a size range. Incomplete areas -- if any are present at all -- are completely lost in the complexity. Many display angles possible. If you like big, affordable specimens then this one is for you.







17048:
Quartz - $75
Shingle Springs District, West Belt, El Dorado County, California
Large cabinet - 20 x 15 x 9 cm (8 x 6 x 3.5 inches)
ex Gene Reynolds collection
Specimen status: Sold

A large cluster of colorless, mostly transparent quartz points from California gold country. Individual crystals reach more than 9 cm in length and more than 3 cm in width. Some missing terminations, but mostly around the edges. Sits beautifully for display on its naturally flat base. The notation on back of one of the accompanying labels reads "from Jerry Wentling who purchased a Placerville [California] rockshop about 1959 and this piece was the window display specimen".







17049:
Quartz
near Placerville, Placerville District, Mother Lode Belt, El Dorado County, California
Large cabinet - 17 x 12 x 6 cm (7 x 5 x 2 inches)
ex Gene Reynolds collection
Specimen status: Sold

A large California gold country quartz specimen, dominated by an 11 cm, doubly-terminated crystal, mostly transparent. A few of the larger crystals have minor phantoms near the terminations. Most of the larger crystals are complete; the bashed terminations tend to be on the smaller crystals. Sits perfectly for display without needing a stand.




17217:
Andradite (variety Topazolite) and Clinochlore
Yellow Cat Mine, New Idria District, Sean Benito County, California
Large cabinet - 12.1 x 6.4 x 2.9 cm (4.8 x 2.5 x 1.1 inches)
Specimen status: Sold

Yellow-brown, lustrous and translucent andradite crystals to about 6 mm on a nicely contrasting bed of deep greenish-gray clinochlore. Displays well on it plastic stand, but the stand could easily be removed if desired. No damage.




17247:
Scheelite, Löllingite, and Molybdenite
Huanggang Fe-Sn Deposit, Hexigten Banner, Ulanhad League, Inner Mongolia Autonomous Region, China
Small cabinet - 7.7 x 5.3 x 2.5 cm (3.0 x 2.1 x 1.0 inches)
Specimen status: Sold

A gray, opaque scheelite crystals measuring 4.4 cm wide sits atop a matrix of wonderfully metallic löllingite crystal matrix, having a flaky look. The scheelite's gray color is imparted by microscopic molybdenite inclusions; some molybdenite blebs are also visible to the naked eye. The scheelite has a somewhat granular texture, and (as is usual) glows a brilliant blue-white under shortwave UV. No damage.







17254:
Gypsum/Glauberite - $22
Lakeside, Great Salt Lake South Arm, Box Elder County, Utah
Small cabinet - 7.4 x 5.8 x 1.5 cm (2.9 x 2.3 x 0.6 inches)
Specimen status: Available     Send email to order

A flat, translucent and essentially colorless crystal, resembling an alien spaceship. Minor mud inclusions. The crystal shape is correct for glauberite, but when I tried dissolving one of these in water, a significant amount of insoluble residue was left. In addition, the Great Salt Lake frequently deposits gypsum crystals. Hence I believe these have some gypsum content as well. No damage.




17255:
Gypsum/Glauberite - $22
Lakeside, Great Salt Lake South Arm, Box Elder County, Utah
Cabinet - 9.6 x 6.7 x 1.8 cm (3.8 x 2.6 x 0.7 inches)
Specimen status: Available     Send email to order

A flat, translucent to opaque, and essentially colorless crystal, resembling an alien spaceship. Gray mud inclusions. The crystal shape is correct for glauberite, but when I tried dissolving one of these in water, a significant amount of insoluble residue was left. In addition, the Great Salt Lake frequently deposits gypsum crystals. Hence I believe these have some gypsum content as well. No damage.




17291:
Meyerhofferite
Gower Gulch Mine, Zabriskie Point, Black Mountains, Amargosa Range, Inyo County, California
Miniature - 4.8 x 2.8 x 2.6 cm (1.9 x 1.1 x 1.0 inches)
Specimen status: Sold

This specimen is composed of radiating sprays of translucent to opaque meyerhofferite crystals. Some terminated, some not. An affordable example of meyerhofferite, an uncommon hydrated basic calcium borate, CaB3O3(OH)5 ˇ H2O.




17292:
Hydroboracite
Boraxo Mine, Ryan area, Death Valley, Death Valley National Park, Inyo County, California
Miniature - 3.6 x 3.2 x 3.0 cm (1.4 x 1.3 x 1.2 inches)
Specimen status: Sold

A nicely divergent spray of translucent hydroboracite crystals, most of which are sharply terminated. Hydroboracite is an uncommon hydrated basic calcium magnesium borate, CaMg[B3O4(OH)3]2 ˇ 3H2O.




17345:
Wulfenite
Erupción Mine, Los Lamentos Mountains, Mun. de Ahumada, Chihuahua, Mexico
Cabinet - 7.6 x 4.4 x 2.5 cm (3.0 x 1.7 x 1.0 inches)
Specimen status: Sold

This specimen is nearly 100% nicely lustrous, butterscotch-colored wulfenite, ranging from opaque to translucent. Wonderful texture and multiple display possibilities. Very minor edge chipping seen with a hand lens, but otherwise the specimen is pretty much pristine.







17535:
Pentagonite - $24
Wagholi Quarries, Wagholi, Nasik District, Maharashtra, India
Small cabinet - 6.8 x 4.2 x 3.5 cm (2.7 x 1.7 x 1.4 inches)
Specimen status: Available     Send email to order

A tuft a beautiful blue pentagonite sits atop a carpet of tiny, sparkling heulandites. This in turn rests on a typical Deccan plateau basalt matrix. The pentagonite cluster is a little contacted, which is why the specimens isn't $75. The basalt matrix has been sawn, because this volcanic rock is very tough and diamond sawing is the only way to extract specimens without damage. However the sawn base makes for excellent display. Three years ago Indian mineral wholesalers indicate that the cavansite-producing quarries are either worked out, flooded, or otherwise abandoned, and the cavansite/pentagonite supply is now only a trickle of what it was on the past, with no immediate hopes for more production.
