This cabinet specimen consists of a goethite/limonite base that is partly covered with scattered Adamite crystals. These crystals do not exceed 0.3" (8 mm) in diameter and are generally in very good condition, as only a few are visibly damaged. Their orthorhombic form is mostly convoluted due to intergrowth, but is still evident and actually good in individual crystals. All have the standard pale, yellow-green coloration and a rather dull, vitreous-to-greasy luster, and are transparent but dimly clear due to inclusions. One face of the limonite base is covered with these crystals, but they are in turn covered with a thin crust of more limonite, hiding their color and luster.
