Scores of tiny, intergrown Orpiment crystals coat the black base of this hand specimen. These crystals do not exceed 0.1" (3 mm) in length or diameter and are generally in good condition - those that are directly exposed tend to be broken, but many are protected and in excellent condition. Though heavily intergrown, they appear to have excellent monoclinic prismatic form. Their yellow color is visible, though not obvious, and all have a bright pearly luster and are transparent.
