12918:
Lawsonite and Muscovite (variety Fuchsite) - $25
Reed Station, Tiburon Uplands Nature Preserve, Marin County, California
8.5 x 5.7 x 3.1 cm (3.3 x 2.2 x 1.2 inches)
Specimen status: Available     Click here to order

An intergrown mass of deep green, shining fuchsite flakes and light grayish lawsonsite crystals. Although the lawsonites are mostly incomplete, the specimen is notable for the association (classic for the locality) and the rarity of lawsonite. Lawsonite is a calcium-aluminum sorosilicate, CaAl2(Si2O7)(OH)2 . H2O, for which Reed Station is the type locality. An old label indicates the specimen was collected in 1960.




14701:
Metatorbernite
Pine Mountain, Mitchell County, North Carolina
3.9 x 3.1 x 2.0 cm (1.5 x 1.2 x 0.8 inches)
Specimen status: Sold

Opaque, micaceous, green metatorbernite flakes lying flat on a quartz/feldspar matrix. Individual crystals reach 3 mm along the crystal edge. Highly typical for the species at this locality.




9107:
Calcite pseudomorph after Glauberite - $12
Camp Verde, Camp Verde District, Yavapai County, Arizona
6.3 x 4.5 x 3.3 cm (2.5 x 1.8 x 1.3 inches)
Specimen status: Available     Click here to order

A cluster of opaque but sharp calcite crystals, pseudomorphed after glauberite. The calcites have a surface texture like unglazed porcelain and reach 4 cm along the edge of the largest individual crystal. Many of these classic pseudomorphs are labeled as being gypsum when in fact they are calcite. This is a particularly good, undamaged example.




9291:
Aragonite and Quartz
Monte Cristo Mine, Rush Creek District, Marion County, Arkansas
6.3 x 6.3 x 4.2 cm (2.5 x 2.5 x 1.7 inches)
Specimen status: Sold

A cluster of colorless, transparent to translucent quartz crystals hosts an overgrowth of off-white, opaque aragonite blossoms, like a small coral reef. Displays well without need for a stand. No damage.







9344:
Orpiment - $45
Ormea, Tanaro Valley, Cuneo Province, Piedmont, Italy
7.4 x 6.0 x 2.9 cm (2.9 x 2.4 x 1.1 inches)
Specimen status: Available     Click here to order

A flat plate of nearly parallel, chisel-pointed, orange-brown, translucent orpiment crystals on a mixed sulfides matrix. Individual orpiment crystals reach 1.4 cm in length. Except for a few, scattered rubs (expected with a mineral this soft), the specimen is free of damage. A fine Italian orpiment for the price.







9534:
Sphalerite, Chalcopyrite, Arsenopyrite, and Calcite - $25
Huaron Mining District, Alcides Carrión Province, Pasco Department, Peru
6.4 x 6.0 x 2.1 cm (2.5 x 2.4 x 0.8 inches)
Specimen status: Available     Click here to order

A flat plate of sharply crystalline sphalerite hosts a scattering of chalcopyrite, arsenopyrite, and calcite crystals. The sphalerite is black, highly lustrous, and opaque. The chalcopyrite is bright and brassy, with most of the crystals being intergrown with the sphalerite but otherwise incomplete. Also present are a few small arsenopyrites, and on one face, a dusting of colorless, lightly frosted, translucent calcites. Scattered edgewear, difficult to find under magnification, but otherwise no damage to this interesting assemblage.







9549:
Libethenite and Quartz
Kambove District, Katanga Copper Crescent, Katanga, Democratic Republic of Congo
6.9 x 6.6 x 3.5 cm (2.7 x 2.6 x 1.4 inches)
Specimen status: Sold

Deep green, opaque libethenite octahedra, with a few terminated quartz points, scattered about on matrix. Individual libethenite crystals reach 5 mm, and the majority are complete.




9780:
Lazulite
Graves Mountain, Lincoln County, Georgia
7.3 x 5.1 x 4.7 cm (2.9 x 2.0 x 1.9 inches)
Specimen status: Sold

A rich collection of opaque, blue lazulite bipyramidal crystals on matrix. Individual crystals reach 7 mm across. Many are terminated and even doubly terminated. At least one {100} twin is present. Very typical for the species from this locality.




9811:
Hemimorphite
Wenshan Mine, Wenshan County, Wenshan Autonomous Prefecture, Yunnan Province, China
7.4 x 5.0 x 4.5 cm (2.9 x 2.0 x 1.8 inches)
Specimen status: Sold

Gray-blue to bright robin's egg blue, bubbly and silky hemimorphite crusts on a vuggy matrix. Displays well from several angles without need for a stand. No damage, and very typical for this species from this locality.




9842:
Albite and Microcline - $14
Minas Gerais, Brazil
5.4 x 4.2 x 2.8 cm (2.1 x 1.7 x 1.1 inches)
Specimen status: Available     Click here to order

This feldspar combination specimen features tabular microcline crystals sitting on a microcline crystal matrix. The albites are mostly sharp, colorless and translucent, and reach 2.2 cm across. The microcline is complete (except on two faces where removed from the host rock), opaque, off-white, with a surface like unglazed porcelain.




12394:
Almandine - $14
Salida, Turret District, Chaffee County, Colorado
4.8 x 4.8 x 3.5 cm (1.9 x 1.9 x 1.4 inches)
Specimen status: Available     Click here to order

A fairly large, fairly well-formed, and nearly complete opaque, brown almandine garnet dodecahedron. Traces of the schist matrix still adhere.




12454:
Barite (variety Sand Barite)
Lake Thunderbird area, Norman, Cleveland County, Oklahoma
5.6 x 4.9 x 3.1 cm (2.2 x 1.9 x 1.2 inches)

A wonderfully sharp example of sand-included barite (a 'barite rose'). Aesthetic and free from damage, a fine example from the classic barite rose locality.
