MD-247910 - Wulfenite, Calcite - - Archived

Wulfenite, Calcite from Pure Potential Mine (North Geronimo Mine), Silver District, Trigo Mts, La Paz Co., Arizona, USA [db_pics/mdpics/MD-247910a.jpg]

5.8 x 4.2 x 2.8 cm. This mine produced, rarely, the best red wulfenites for color to my way of thinking. Although in smaller crystals than Red Cloud, they were just more red. This sparkling specimen has several wulfenites to 8mm on a matrix coated with drusy calcite. Ex. Harold Urish Collection.

MD-247922 - Calcite, Cuprite (Var: Chalcotrichite), Copper - - Archived

Calcite, Cuprite (Var: Chalcotrichite), Copper from Concepción del Oro, Mun. de Concepción del Oro, Zacatecas, Mexico [db_pics/mdpics/MD-247922b.jpg]

6.4 x 3.4 x 2.4 cm. Here we have briliant fiery-orange-red calcite crystals colored so nicely by inclusions of the cuprite varietal chalcotrichite. As a bonus, there are small bits of native copper wires growing about the base of the calcites as well, so you can see a very interesting assemblage in one spot. Old material, rarely seen today. Ex. Harold Urish Collection.

MD-248021 - Calcite, Sphalerite - - Archived

Calcite, Sphalerite from Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA [db_pics/mdpics/MD-248021a.jpg]

8.0 x 6.2 x 5.3 cm. A gemmy, nearly colorless, doubly-terminated and twinned crystal of calcite measuring 7.0 cm in length is associated with a cluster of brown sphalerite with gemmy reddish-orange highlights.

MD-248026 - Calcite, Baryte - - Archived

Calcite, Baryte from Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA [db_pics/mdpics/MD-248026a.jpg]

12.2 x 10.8 x 6.9 cm. Only on rare occasions are there more than one or two terminated calcites on matrix from Elmwood. This specimen has four terminated calcite crystals on white sugary baryte. The largest glassy, cognac-colored calcite measures 10.0 cm in length.

MD-248027 - Calcite, Baryte, Sphalerite - - Archived

15.0 x 9.1 x 7.0 cm. This is a huge, twinned, glassy, gemmy, cognac colored calcite on baryte and very minor sphalerite.

Calcite from Elmwood mine, Carthage, Central Tennessee Ba-F-Pb-Zn District, Smith Co., Tennessee, USA [db_pics/mdpics/MD-248029a.jpg]

12.6 x 7.7 x 6.8 cm. Perched aesthetically on a shard of limestone is a gemmy, twinned, doubly-terminated calcite crystal, measuring 12.6 cm across. The terminations exhibit a fine cognac color. The crystal perched in midair, mounted for display by smaller crystals beneath it, and is very elegant.

MD-249187 - Quartz, Calcite, Fluorite - - Archived
Shangbao Pyrite mine, Leiyang Co., Hengyang Prefecture, Hunan Province, China

Quartz, Calcite, Fluorite from Shangbao Pyrite mine, Leiyang Co., Hengyang Prefecture, Hunan Province, China [db_pics/mdpics/MD-249187a.jpg]

6.7 x 5.1 x 4.5 cm. An interesting and very showy pseudomorph from recent finds at the Shangbao Mine of China. Sparkly, drusy quartz has pseudomorphed sharp calcite scalenohedrons on this excellent, damage-free specimen. The large pseudomorph is 4.7 cm and you can see where this and another crystal have been partially dissolved away and then pseudomorphed. Fascinating. Furthermore, the drusy quartz-covered base is sea-green fluorite.

MD-249188 - Pyrite, Calcite (Var: Manganoan Calcite) - - Archived

Pyrite, Calcite (Var: Manganoan Calcite) from Chenzhong (?), Hunan Province, China [db_pics/mdpics/MD-249188a.jpg]

9.9 x 7.8 x 5.0 cm. This find was made a couple of years back in China, and is absolutely unique: glittery, golden pyrite microcrystals on the edges of huge (to 4.8 cm across on this piece) flattened rhombs of pastel-pink manganoan calcite. Some of the specimens had very sparse coverage of pyrite, just a salting, but here, it is richly carpeting the crystal edges and on some of the crystal face. Striking and very pretty material.

MD-249196 - Baryte, Calcite - - Archived

Baryte, Calcite from Frizington, West Cumberland Iron Field, North and Western Region (Cumberland), Cumbria, England, UK [db_pics/mdpics/MD-249196a.jpg]

9.5 x 8.4 x 7.5 cm. A classic, old-time blue baryte specimen from Frizington, England. The capping cluster of glassy blades really highlights this mounded piece, which is richly covered with baryte clusters and hematite-tinted calcite scalenohedrons. Easily 100 years old or older. A really excellent combination specimen from this historic locale. Ex. Robert Lambert and George Elling Collections.

Aurichalcite, Calcite from Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico [db_pics/mdpics/MD-249219b.jpg]

9.3 x 7.9 x 4.6 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Glassy, transparent calcite rhombs to 2.6 cm across are richly and aesthetically strewn in a sculptural vug atop starkly contrasting, sturdy, banded, gossan matrix. The vug is lined with beautiful, robin’s-egg blue aurichalcite needles. Some of the calcite rhombs are included with aurichalcite and some are not, which really adds to the attractiveness of this fine piece. A stunning new find.

5.4 x 5.3 x 4.9 cm. A really fine and aesthetic specimen from recent finds at Irai, Brazil. A beautiful, intergrown cluster of colorless calcite scalenohedrons is dramatically perched atop a pineapple cluster of amethyst crystals. This complete-all-around piece is nearly pristine.

Celestine, Calcite from Holloway Quarry (Rockwood quarry), Berlin Township, Newport, Monroe Co., Michigan, USA [db_pics/mdpics/MD-249305b.jpg]

9.2 x 4.5 x 1.5 cm. A striking, parallel-growth cluster of highly lustrous, translucent, tabular, blue-gray celestine blades beautifully and aesthetically highlighted by starkly contrasting, golden-amber calcite crystals. The celestine crystals have very distinctive and very unusual pinacoid terminations. The calcites on the edge look like a row of golden shark teeth. You don’t see many of these Holloway Quarry celestine and calcite combinations available. Ex. John Medici Collection, one of the premiere Midwest field collectors. He collected this piece himself.

Calcite from Berry Materials Corp. Quarry (North Vernon Plant), North Vernon, Jennings Co., Indiana, USA [db_pics/mdpics/MD-249319a.jpg]

3.1 x 1.8 x 0.8 cm. A beautiful, gemmy and lustrous, golden-amber, V-twin calcite crystal from the Berry Materials Quarry of Indiana. Textbook crystal form, complete-all-around and pristine. Classic matrix material from this well-known locale. Ex. Jaime Bird Collection.

12.0 x 11.9 x 6.4 cm. An uncommon, fine, cabinet combination specimen from the less well-known Erfurt Way locality in Austria. Quartz and pericline (an albite varietal) are rare from here, but here we have a very glassy complex of quartz crystals nicely accented with a couple of clusters of bone-white pericline crystals, scattered snow-white calcite rhombs and lustrous, wine-red rutile needles included in the quartz crystals. Ex. Alois Steiner and Rolf Wein Collections.

5.5 x 5.5 x 3.5 cm. A very sharp array of bladed calcite crystals, in an unusually displayable specimen for this locality which usually produces calcite in jumbly masses. Translucent. Ex. William Larson Collection.
