25987:
Aragonite
Sweet Water Mine, Morro Bay, San Luis Obispo County, California
Miniature - 6.0 x 5.2 x 4.6 cm (2.4 x 2.0 x 1.8 inches)
ex Ed and Carol Headley collection
Specimen status: Sold

A spray of translucent, slender, and quite white aragonite needles, many of which are terminated. Mindat lists the locality as a chromite mine (and six miles inland from Morro Bay), with no mention or aragonite at the deposit.




26044:
Mimetite and Calcite - $8
Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico
Cabinet - 9.2 x 4.4 x 4.4 cm (3.6 x 1.7 x 1.7 cm)
Specimen status: Available     Send email to order

Matte, olive-drag green mimetite blobs scattered about on a typical Ojuela Mine gossan matrix. Also present are small, opaque white calcite crystals. The mimetites and calcite both max out at 4 mm. Your basic Ojuela mimetite specimen.




26486:

Köttigite/Parasymplesite with Gypsum

Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico
Miniature - 4.0 x 3.1 x 1.7 cm (1.6 x 1.2 x 0.7 inches)
Specimen status: Sold

A typical Ojuela Mine gossan matrix hosts several sprays of opaque, greenish-gray köttigite/parasymplesite crystals scattered among blocky, colorless, mostly transparent gypsum crystals. The gypsum crystals reach 1.2 cm, and those around the edges have damaged termination. (This is typical for a mineral as soft and easily cleaved as gypsum.) A pleasant treat under the hand lends or camera lens. Köttigite (a hydrated zinc arsenate) and parasymplesite (a hydrated iron arsenate) cannot be distinguished by visual inspection, and might even be intergrown or form zones within the crystal sprays.




26554:
Rocksmiths Farewell Tour Van Bank
Large cabinet - 16.5 x 7.4 x 7.3 cm (6.5 x 2.9 x 2.9 inches)
Specimen status: Sold

The Rocksmiths were a nationally recognized and quite popular mineral company. I made a point of visiting them first at any shows I attended, and made many affordable purchases. In 2002, they had a Farewell Tour: their last round of shows before retiring. During the Tour a limited number of these 1964 Dodge van-banks were available. This is number 144 of 504. The side doors open and the wheels turn. The bank box is inside the van body, and deposited money can be accessed using a golden key (still present!) to unlock a door on the bottom of the van. This example is pristine. This is only the second example I have ever seen for sale. A must for the collector of mineral or mineral dealer memorabilia!







26555:
Calcite - $10
Mexico
Miniature - 3.4 x 3.3 x 1.7 cm (1.3 x 1.3 x 0.7 inches)
Specimen status: Available     Send email to order

A sharp calcite cleavage section, in which double refraction is quite obvious.




27687:
Villiaumite, etc.
Koashva Mountain, Khibiny Massif, Murmanskaya Oblast', Northern Region, Russia
Miniature - 4.3 x 3.2 x 3.0 cm (1.7 x 1.3 x 1.2 inches)
Specimen status: Sold

From a locality know for an array of rare minerals comes this complex specimen, containing cranberry red to brown villiaumite (among other unidentified species, and probably including natrolite). Obvious cubic cleavage panes are present, as well as a few complete crystal faces.







27691:
Villiaumite, etc. - $10
Koashva Mountain, Khibiny Massif, Murmanskaya Oblast', Northern Region, Russia
Miniature - 3.7 x 2.5 x 1.8 cm (1.5 x 1.0 x 0.7 inches)
Specimen status: Available     Send email to order

From a locality know for an array of rare minerals comes this complex specimen, containing a cranberry red villiaumite crust on one face, along with other unidentified mineral species scattered about (probably including aegirine).




27937:
Quartz epimorph after Calcite
Crystal Cave, Ouray, Ouray District, San Juan Mountains, Ouray County, Colorado
Cabinet - 6.2 x 5.5 x 2.6 cm (2.4 x 2.2 x 1.0 inches)
Specimen status: Sold

This specimen started out as a parallel pair of doubly-terminated scalenohedral calcite crystals. These became coated with a layer of translucent white quartz, which also collected a little iron during deposition. Later the calcites dissolved away, leaving this sharp epimorph. The yellow is absorbed into the quartz; it does not change upon treatment with Super Iron Out. A fine Colorado epimorph, from a classic location for such epimorphs, where the casts are usually not as complete, and the color usually snow white. One 'termination' appears contacted but no damage is noted.




28216:
Fluorite - $14
Chenzhou Prefecture, Hunan Province, China
Cabinet - 7.1 x 5.5 x 4.6 cm (2.8 x 2.2 x 1.8 inches)
Specimen status: Available     Send email to order

A deep-green translucent chunk of fluorite, with one face composed of small distinct crystal faces. The other faces are cleaved or etched. Beautiful blue color when backlit. Carving rough...?







28601:
Microcline
Skardu District, Baltistan, Gilgit-Baltistan, Pakistan
Cabinet - 6.9 x 6.0 x 5.9 cm (2.7 x 2.4 x 2.3 inches)
Specimen status: Sold

A spray of stout, opaque but glassy microcline crystals. Minor chipping bot otherwise no damage to the display face. Sits well for display as shown without needing a stand.
