The limonite base of this display piece is partly covered with many rounded, radiating Adamite clusters. Though a few of these are damaged, most are in excellent condition. They contain crystals that reach lengths of 0.4" (1 cm) and have good orthorhombic prismatic form, considering their tight arrangements. All have the common dull yellow-green color and adamantine luster and are translucent. They glow a bright green when placed under shortwave ultraviolet light. A few tiny calcite crystals are also present.
