A thin crust of light green aurichalcite on limonite gives way to glassy and translucent rhombs of calcite, to 1.0 cm across. Most of the rhombs are included by fibrous aurichalcite, which, in turn, emits a glowing, rich teal, color. A few rhombs have not been included by aurichalcite, and these are basically colorless, a nice accent.
