Bournonite crystals from Bolivia rank among the world's finest. This locality seems to produce a pocket or two every year, but this year's examples are bit larger and finer than usual. Some specimens are complete pseudomorphs of tetrahedrite after bournonite, but this is a fresh example. This is essentially a single crystal, with a bit of attached matrix. The crystal has interesting growth marks, reflecting its symmetry.
