TB37: Calcite doubly terminated

Aerial, with the two tips unbroken, and very well placed on the matrix. It also has good contrast between the matrix's colorless Calcite and the orangish main crystal. Esthetics!

Main crystal size: 5 × 2.6 cm = 1.97” × 1.02”
Price: [SOLD]

JH14E5: Calcite doubly terminated

This one appeals to me because it is unusual. The Calcite crystals, which are very well defined, doubly terminated, and clear, appear to be randomly spread across the dark matrix.
Minerva I Mine, Ozark-Mahoning group, Cave-in-Rock Sub-District, Hardin County, Illinois USA (±1980)

11TP46: Calcite epitactic Rhodochrosite, Sphalerite, Pyrite

Rich group of Calcite crystals in epitactic growth on Rhodochrosite. The rhodochrosite acted as a substrate which controlled the shapes and orientations of the younger Calcite crystals. The specimen is completed by crystals of Sphalerite which form the matrix, and tiny crystals of Pyrite sprinkled between the white Calcite crystals.

SE97AC7: Calcite on Aragonite and Sulfur

Aggregate of very flattened Aragonite crystals with their characteristic pseudohexagonal shape. The surfaces of their faces are coated by small Calcite crystals and they have deformed Sulfur crystals on the back. As is the case with so many specimens in this collection, in this case a great Italian classic, the sample is of great quality for the locality.
Cozzo Disi Mine, Casteltermini, Agrigento (Girgenti) Province, Sicily Italy

Price: €80 / US$85 / ¥13050 / AUD$130

ET60E4: Calcite on Dolomite

I think the photo says more than I can explain. The white crystals are not what they look like: they are Calcite, so don’t be mistaken. The brown ones are what they look like: Dolomite.
Roata Mine, Cavnic, Maramures Romania (2004)
Specimen size: 3.5 × 3.4 × 2.9 cm = 1.38” × 1.34” × 1.14”

Price: [SOLD]

RR46G0: Calcite on Quartz

Excellent representation of Calcite from Guanajuato. The specimen is especially esthetic due to the aerial position of flat rhombohedral crystals, with a lenticular habit, on a matrix of lightly violet Quartz.
