Thick, heavy vein section of Silver in Calcite, a 2.3cm thick slab sawcut on both sides. There is a layer of solid Silver along the more straight edge, with the rest of the specimen filled with more dendritic Silver. Visually, it appears to be 40-50% Silver, and by weight, a much larger percentage. The specimen is quite hefty and was the best slab (richest, largest, thickest) out a large lot of Cobalt Silver I purchased from a Canadian miner over 20 years ago.
