23030:
Chalcedony Epimorph after Calcite with Stilbite
Nasik District, Maharashtra, India
Cabinet - 10.0 x 2.9 x 2.5 cm (3.9 x 1.1 x 1.0 inches)
Specimen status: Sold

A nifty, translucent and hollow chalcedony epimorph after calcite (assumed to be calcite due to the distinct rhombohedral shape of the shell). The opaque, peach stilbite sidecar crystal is 4.4 cm long. Unusual!







23041:
Calcite - $32
Guanajuato, Mexico
Large cabinet - 12.4 x 9.2 x 2.4 cm (4.9 x 3.6 x 0.9 inches)
W. M. Foote label
Specimen status: Available     Send email to order

A flat matrix plate host a complete coverage of colorless, translucent to opaque calcite crystals. The largest of these calcites is 2.4 cm in size. A few minor, scattered bruises and cleaves noted. Under both longwave and shortwave UV the specimen exhibits a light pink fluorescence. Also notable is the W. M. Foote label, dating the piece to the 1895-1916 period. Note: this is **not** an Albert Edward Foote label! Numerous dealers and collectors attribute any specimen bearing 'Foote' on the label to A. E. Foote, who sold minerals in Philadelphia in the 1876-1895 period. However (I strong believe) that when A. E. passed in 1895 and his son Warren Mathews Foote inherited the business, 'A. E.' was no longer used on the labels.







23079:
Scheelite - $36
Mt Xuebaoding, Pingwu County, Mianyang Prefecture, Sichuan Province, China
Miniature - 4.8 x 4.3 x 4.2 cm (1.9 x 1.7 x 1.7 inches)
Specimen status: Available     Send email to order

A lustrous, butterscotch, mostly opaque scheelite crystal perched on a nest of muscovite.The scheelite has three distinct termination peaks, reminiscent of the mountain range from which it comes. As is typical for most examples, the scheelite exhibits brilliant blue-white fluorescence under shortwave UV. Minor albite and beryl also present. No damage to the display faces. Sits well for display as shown without needing a stand.







23124
Sphalerite and Quartz - $150
Picher Field, Tri-State District, Ottawa County, Oklahoma
Large cabinet - 13.5 x 10.1 x 7.7 cm (5.3 x 4.0 x 3.0 inches)
Specimen status: Available     Send email to order

Something a little different from Picher Field! A cluster of rather large, dark amber, quite lustrous, modified sphalerite crystals with a blanket of sharp and colorless quartz crystals, a bit like ice from a late-season snowstorm. The largest individual quartz crystal is 2 cm (a monster for the locality). A few second generation sphalerites sit atop the quartz. Sits perfectly for display as shown on a naturally flat sphalerite face. Minor rubs and scratches, but nothing significant on the display face. Kinda nifty!







23290:
Beryl and Muscovite - $26
Mt Xuebaoding, Pingwu County, Mianyang Prefecture, Sichuan Province, China
Large cabinet - 15.2 x 8.6 x 3.1 cm (6.0 x 3.4 x 1.2 inches)
Specimen status: Available     Send email to order

A flat matrix plate hosts several colorless, tabular beryl crystals, translucent to transparent, on a bed of silvery gray muscovite. Individual beryl crystals reach 2.2 cm across. The beryls are undamaged and the muscovite (for the most part) not matted down. Very typical for these minerals from this famous Chinese locality.







23293:
Gypsum included with Copper
Mission Pit, San Xavier, Pima District, Pima County, Arizona
Miniature - 3.5 x 2.7 x 1.3 cm (1.4 x 1.1 x 0.5 inches)
ex Ed and Carol Headley collection
Specimen status: Sold

A small but very rich example of this classic association! The water-clear gypsum is jam-packed with a forest of bright copper dendrites. Easily visible to the naked eye, and a feast under the hand lens or camera lens. I've seen many examples of this material over the years, and this is among the richest.




23436:
Malachite - $14
Milpilas Mine, Cuitaca, Mun. de Cananea, Sonora, Mexico
Miniature - 4.8 x 3.7 x 1.6 cm (1.9 x 1.5 x 0.6 inches)
Specimen status: Available     Send email to order

A specimen of deep green, velvety malachite, partly contacted on the larger surfaces due to growth in a narrow fissure.







23446:
Mimetite
Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico
Cabinet - 7.3 x 5.1 x 2.5 cm (2.9 x 2.0 x 1.0 inches)
Specimen status: Sold

A gossan limonite matrix hosts a rich coverage of tan, wheat sheaf to bow tie cluster mimetites. The reverse has less mimetite, where it is yellow. A few incomplete crystals, mostly around the edges, do not detract from the display face.







23595:
Adamite and Calcite - $10
Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico
Cabinet - 6.2 x 5.0 x 2.7 cm (2.4 x 2.0 x 1.1 inches)
Specimen status: Available     Send email to order

A gossan matrix hosts golden yellow adamite and colorless calcite crystals in one cleft, and just calcite in another. Under both longwave and shortwave UV the adamite glows bright green, and the calcites fluoresce white. Sits for display as shown without needing a stand. A very affordable Ojuela Mine adamite specimen.







23613:
Adamite - $8
Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico
Miniature - 4.7 x 3.3 x 1.8 cm (1.9 x 1.3 x 0.7 inches)
Specimen status: Available     Send email to order

A limonite gossan matrix is nearly completely covered with small but sparkly adamite crystals. These adamites are highly lustrous, a pale golden yellow color, and reach 4 mm. Weak green fluorescence under longwave UV, and significantly brighter green under shortwave. Some incomplete crystals along the edges, but no other damage is noted.




23819:
Chalcopyrite and Quartz - $6
Zacatecas, Mexico
Miniature - 3.9 x 3.1 x 2.3 cm (1.5 x 1.2 x 0.9 inches)
Specimen status: Available     Send email to order

A small miniature specimen, composed of a spray of milky, translucent to opaque quartz crystals perched on a very dark chalcopyrite crystal cluster. The largest quartz is 3.9 cm long and doubly terminated. The chalcopyrite cluster forms a natural display stand. No damage. Probably from the Cobre Mine. Old material - from a horde assembled in the 1970's.







23827:
Quartz, Chalcopyrite, and Calcite
Zacatecas, Mexico
Cabinet - 6.3 x 5.3 x 2.9 cm (2.5 x 2.1 x 1.1 inches)
Specimen status: Sold

A matrix of terminated quartz points which reach 2.2 cm in length host numerous clusters of sharp, iridescent chalcopyrite. The quartz crystals are milky and translucent at the bases, transitioning to clear at the terminations. The chalcopyrites reach 9.5 mm across. Accented with a dusting of small, white calcites. Minor pyrite also noted. No damage. Probably from the Cobre Mine. Old material - from a horde assembled in the 1970's.
