Aurichalcite in Calcite
Ojuela Mine, Mapimi, Durango, Mexico
Small Cabinet, 7.0 x 4.2 x 4.2 cm
A very RICH, intensely colored cluster of equant, lustrous and translucent calcite rhombs, to 1.8 cm, is emplaced on ocherous limonite. The crystals, are, in turn, colored a rich blue by fibrous inclusions of aurichalcite. This is one of the richest overall paltes of solid colored crystals from the find. When closely examining the calcite, it is possible to see the fibrous aurichalcite crystals preserved inside, thus showing that this is intergrowth, as much or more so than simple inclusions. Some crystals of calcite may be more aurichalcite than calcite now! The color is, truly, mesmerizing! Because they are also lustrous, this is hard to photograph and I assure you the color and luster both are better in person because we had the camera compromise to try to get each in some degree.
