ID: CC19964
Intergrown cog-like crystals of Bournonite with a little attached granular Quartz and Limonite from the Viboras mine in the Machacamarca mining district of Cornelio Saavedra Province, Bolivia.  The Bournonite forms excellent classic cog wheels of gunmetal-grey with a bright metallic lustre.  The largest crystal measures 2.9 cm long x 0.9 cm wide and up to 2 cm deep and is joined with two sub-parallel, similar but smaller crystals.  A superb example of Bournonite, commonly known as “cog-wheel ore”.
