Enargite is a signature mineral species, indeed one of the 'Holy Grails', of the Butte District in Montana. This is fine, old-time combination piece is dominated by tabular Enargite prisms, accented with Pyrite crystals and a small amount of Quartz crystals, all on granite matrix. The striated Enargites range up to 1.7 wide, and most have a very good luster. The brassy and lustrous Pyrites range up to about .3 cm, and the infrequent Quartz crystals about the same. These are sought-after classics, and the aesthetics on this cabinet specimen are good. Better in person. Also, this is a rarely seen cabinet specimen from this classic old locality.
