“A cleft in massive pyrite matrix opens to reveals bright and brassy pyrite crystals with nice striations and distinctly curved faces. The largest crystal is about 1.5 cm across. The Canutillos Mine is noted more for its tin and silver minerals than for collectable pyrite. Size of specimen: 7.9 x 5.9 x 4.2 cm (3.1 x 2.3 x 1.7 inches)”
