A druse of snow white, quartz crystals is the matrix for color contrasting, splendent, battleship gray, short prismatic, striated, crystals of enargite. The largest enargite crystals reach .7 cm across. A few crystals are even doubly terminated. The contrast is striking between the lustrous enargite an dthe beautiful underelaying quartz! Note the HUGE price at the time, from Hugh Ford, at least 50 years ago if not more.
