Several Neptunite crystals are heavily intergrown on this specmien, and make up most of its mass. These crystals do not exceed 1.0" (2.5 cm) in length and are all in good condition due to widespread light damage and slight weathering. Though intergrown, their monoclinic prismatic form is still fairly good, with well-defined edges and sometimes pitted but clean faces that often possess a bright, nearly adamantine luster.
