Here is a large vein section showing very dense cobalt arsenides laced with thick veinlets and globs of native silver. The silver has been totally remobilized out of the arsenides and re-deposited as the veins and globs. Quite something! Calcite on one side and Cobalt sediment on the other side of the vein. Heavy! Weighs, probably 15 pounds or so! Great geological, as well as mineralogical specimen. Extra postage required!
