This large thumbnail specimen consists of a single Lorenzenite crystal that rests in what appears to be a metamorphic host rock. The crystal has dimensions of 0.9 x 0.6 x 0.3" (2.3 x 1.5 x 0.8 cm) and is in excellent condition, showing only very minor damage on a few of its most exposed edges. Its orthorhombic prismatic form is excellent, with well-defined edges and clean faces that possess either a dull, waxy or a matte luster. Its color is a moderately dark brown and it is definitely opaque. The host rock in which it rests is dark gray in color and is permeated by many thin, black needles of a mineral that I cannot identify.
