A dusting of fibrous, blue aurichalcite covers its limonite matrix. Set in the center of the specimen is a lustrous and translucent, equant, calcite rhomb, measuring 1.1 cm across. The rhomb is colored a rich blue from fibrous inclusions of aurichalcite. STARK isolation and drama make this, if not a pricey piece, one of the most interesting visually as a collectible.
