Calcite
Superb cabinet Calcite from Tsumeb, Namibia (South West Africa). Collected before 1977. Crisp calcite rhombohedrons are lightly dusted with hematite, on a matrix of mixed, unidentified alteration products. Very aesthetically pleasing, a beautiful specimen. This specimen measures about 10.8 cm x 7.3 cm x 4.5 cm. The largest crystal is about 2 cm x 2 cm x 2 cm. Calcite # 096 – Price: $US 2495. |
Calcite
Calcite from the exceptional Blackdene Mine, Weardale, Durham, England, this museum-quality specimen has several flattened rhombohedral calcite crystals perched on top of a mass of large quartz crystals. Very attractive piece. This unique specimen measures about 14 cm x 9 cm x 6.5 cm. The flattened calcites are each about 2 cm across. Calcite # 014 – Price: $US 450. |
Calcite
Calcite from Pitcher, Oklahoma, USA. Collected before 1980. Accessory pinkish dolomite crystals and micro pyrite crystals, on sedimentary breccia. This specimen measures about 3.6 cm x 2.4 cm x 2 cm. The calcite crystal is 2.5 cm x 1.5 cm x 1.3 cm. A nice example of a trigonal termination (major and minor both present). Calcite # 095 – Price: $US 35. |
Calcite and Dendrites
Calcite from Cumberland, England. Collected before 1980. Especially interesting are dendrites growing in part of a crystal. Nice crystals, too. This specimen measures about 2.6 cm x 3.0 cm x 2.5 cm. Calcite # 371 – Price: $US 65. |
Calcite
Calcite on natrolite and tetranatrolite from the De Mix Quarry, Mont St. Hilaire, Quebec, Canada. This 5 mm crystal was self-collected in 1973, in the days when faced with an impossible crystal form at St. Hilaire, we used to say, 'it must be calcite' — well, this crystal that appears to be essentially an octahedron modified by a dodecahedron, has been verified by XRD. Minor biotite as an accessory. This thumbnail specimen measures about 15 mm x 12 mm x 14 mm. Calcite # 271 – Price: $US 20. |
Calcite
Very unusual Calcite scalenohedrons, coated with red hematite and accessory chalcopyrite; from the Faraday Mine, Bancroft, Ontario, Canada. Collected, ca. 1957. This specimen measures about 3.7 cm x 2.2 cm x 1.8 cm. Calcite # 272 – Price: $US 150. |
Calcite
Great Calcite as white tabular hexagonal crystals to 1.8 cm. on a druse of aragonite micro crystals and vaterite mat. Collected 1976 at Christafor, Entracque, (Cuneo), Italy. Very unusual assemblage in an attractive specimen. Photos show top and bottom. This specimen measures about 7.8 cm x 5.7 cm x 4.5 cm. Calcite # 273 – Price: $US 125. |
Calcite
Calcite pale yellow hexagons with trigonal terminations. Collected before 1980 from Pitcher, Oklahoma, USA. Accessories include dolomite, micro-pyrite, marcasite, on sediment. This specimen measures about 6.2 cm x 4 cm x 4 cm. Calcite # 275 – Price: $US 35. |
Carletonite
Carletonite from the DeMix Quarry, Mont St. Hilaire, Quebec, Canada; the type locality for this rare mineral, collected in 1970. Pearly white massive and prismatic in vug, accessory green arfvedsonite crystals, purple fluorite, massive pink albite, quartz and yellow narsarsukite. Identified Dr. George Chao XRD, probe. This specimen measures about 5.7 cm x 4.2 cm x 2.5 cm. Carletonite # 015 – Price: $US 45. |
Carnotite
Carnotite as pale yellow encrustations and layers. Collected before 1978 from Montrose County, Colorado, USA. On and in water soluble sediment. Because of the moderate gamma radiation from this mineral, special packing and/or shipping may be required to your destination. This special handling may be at extra cost. This specimen measures about 4.8 cm x 4.2 cm x 1.3 cm. Carnotite # 462 – Price: $US 35. |
Caryopilite
Caryopilite, as dark brown micro-reniform habit, is from the type locality for this rare mineral, the Harstigen Mine, Pajsberg, Låban, Värmland, Sweden; collected before 1978. This specimen measures about 4.8 cm x 3.0 cm x 2.0 cm. Caryopilite # 440 – Price: $US 75. |
Cassiterite
Honey-brown to nearly black tetragonal pyramidal Cassiterite crystals from the Cligga Head Mine, St. Agnes, Co. Cornwall, England. Collected before 1978. The crystals are in a cavities with accessory chlorite, in a mica schist. This specimen measures about 5.6 cm x 4.5 cm x 2.5 cm. Cassiterite # 143 – Price: $US 125. |
Catapleiite
Catapleiite as colorless transparent plates to 5 mm in vugs. Accessories include albite, acmite, siderite; from De Mix Quarry, Mount St. Hilaire, Quebec, Canada. Collected October, 1975. This specimen measures about 8.5 cm x 4.5 cm x 4.2 cm. Catapleiite # 306 – Price: $US 50. |
