A cluster of intergrown, lustrous and translucent, equant, calcite rhombs, to 2.0 cm across, are emplaced on a limonite matrix. Fibrous inclusions of aurichalcite have resulted in the crystals exhibiting a rich blue color. Super, complex intergrown geometry and large crystal size make this a VERY impressive piece, with shocking intense color that looks fake. There is some minor damage to smaller crystals, hence the lower price compared to other pieces. 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 lustre both are better in person because we had the camera compromise to try to get each in some degree.
