This hand specimen consists of a druse of small Sphaerocobaltite crystals that covers part of a gray, quartz-laden host rock. These crystals line a shallow depression in the rock, and so are somewhat protected and in very good condition. They do not exceed 0.1" (3 mm) in diameter as individuals, and are heavily intergrown so that one cannot easily study their form. They do have a visible rhombohedral form, however, with well-defined edges and heavily patterned but clean faces that possess a pearly luster. All have a rather intense pink coloration that is a primary characteristic of this mineral, and are generally translucent and show dim transparence in some areas. There are many tiny smatterings of malachite around the Sphaerocobaltite druse, but these are very small and amorphous.
