- Aurichalcite in Calcite

Like an aqua-blue ocean lapping up on an ocherous island beach, lustrous and translucent, rhombs of calcite, to 1.7 cm across have been colored a rich blue color by fibrous inclusions of aurichalcite. This is definitely evocative of a tropic isle and water (says my helpers here!). It is surely one of the most impressive pieces overall for color intenstiy, crystal definition, and overall aesthetics in this size range. 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.
