Watch List notes:

Natural gold nugget from the Sacramento River in California, 513 grams, 95% fine, the "Golden Seal." Roughly 4" x 1-1/2" x 1/2". A long and hefty natural lump of gold with smoothed edges from centuries of alluvial transport, with a few small pockets left but no remaining quartz matrix, nicknamed the "Golden Seal" for the fact that it looks like a swimming seal with its head slightly raised from the water surface, with rich gold color all over indicative of its high fineness.
