Rather equant, glassy and translucent, rhombs of calcite, to 1.5 cm across, have been infused by fibrous aurichalcite, resulting in an intense teal coloration. Very minor edge wear is present but insignificant in context as this has sharp geometry and the most intense color of any here but perhaps 2 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 luster both are better in person because we had the camera compromise to try to get each in some degree.
