This Illinois combo piece is TRULY dramatic, with its sharp, silvery 3-cm crystal of galena (with textbook form) contrasting beautifully with deep purple cubes of fluorite (to 1.5 cm). The galena is complete all around, 360. This is a very rare combo for the region, and a particularly aesthetic piece, from a long-closed mine 7.7 x 4.2 x 2.5 cm
