THIS is a fantastic specimen of dendritic native silver coated by cobalt arsenides in carbonate vein matrix. The silver exhibits branching dendritic stricture at the coreof the arsenide, probably safflorite, "rosettes". As well there are lots of veinlets of pure silver coursing through the vein section. This is representative of a real ore-grade vein-section from the heydays of the Cobalt mining camp. Sawn on one side, rough on the other. Looks great!
