The mine at Charcas in San Luis Potos', Mexico, is known for 25 different mineral species, but amongst these Calcite is probably the most diverse for it wide range in habit and structure. This attractive cabinet specimen has a core of massive Calcite veinstuff over which all surfaces, bar the base, are completely coated with hexagonal plates of colour-zoned Calcite crystals, commonly referred to as 'poker chip' crystals. The hexagonal plates attain 1.7 cm across flats and are typically 3 to 4 mm thick. Each plate has a colourless translucent outer rim which, on the flattened termination faces rapidly grade to a semi-opaque snow-white face and centre, sometimes with a Mercedes-Benz trigonal grey imprint. Although not recorded, this specimen could be from the 1960's find at the San Sebastian mine within the Charcas mining district. A fine Calcite from the Josef Clemente Collection of southern Germany.

Calcite from Charcas, Mexico
Charcas calcite is one of the great immediately recognizable Mexican calcite styles: flattened, sharply hexagonal rhombohedra stacked like a pile of white-to-gray poker chips, often with satiny or pearly broad faces and glassier edge faces. Good examples have a sculptural, almost architectural quality — single fat disks, stepped stacks, V-shaped clusters, columnar growths, or matrix-free “floaters” that seem too deliberate to be accidental. The classic palette is colorless, white, cream, gray, slightly smoky, and occasionally pinkish; many specimens show a pink to red fluorescence that is part of the locality’s appeal for UV collectors.
