Aurichalcite in Calcite
Ojuela Mine, Mapimi, Durango, Mexico
Small Cabinet, 5.7 x 5.1 x 4.0 cm
Equant, lustrous and translucent rhombs of calcite, to 1.7 cm across have been differentially included by fibrous aurichalcite, resulting in a two-tone blue appearance. These crystals are perched on fibrous, pastel blue aurichalcite, which, in turn, is emplaced on ocherous limonite matrix. Excellent example of CALCITE from this find, more than most pieces which are simply for color or the lure of the association
