OK, this is not a very pretty specimen from Magnet Cove, Hot Springs County, Arkansas. It is a "floater" cluster of quartz crystals with three or four black metallic well formed brookite crystals, the nicest one perched pertly on the edge. The quartz crystals are smoky due to radiation and included with other minerals to give a mottled grey-green look. No damage. Measures 1.5 x 1.5 x 1 inches ( 3.8 x 3.8 x 2.5 cm).
