This is a super lustrous and fine, large crystal of arfvedsonite. It is significant for the species not just for the outright quality and luster, but for the location as well - an unusual mineralogical occurrence known as the type locality also for zektzerite and okanoganite. It is well terminated all around except for a contact point on the back of the termination. For a black mineral, its awfully good!
