The drusy quartz base of this small hand specimen contains four small clusters of heavily intergrown Sphalerite crystals. All of these show some noticeable damage, and at least one is incomplete. The largest of these clusters averages 0.5" (1.3 cm) in diameter, and the others are measure about half that. All have noticeable cubic-based form, though the intergrowth of their crystals makes their exact form difficult to define; three of them appear to show evidence of twinning, however. All have a moderately dark brown coloration and an adamantine luster, and are dimly to moderately transparent, depending on their size. The drusy host rock on which they rest is made up of integrown plates of microcrystalline quartz that are covered with tiny, milky-white quartz crystals.
