Genuine Mammoth Tusk  3 1/2" diameter x 41" long, over 17 pounds, nice curve, handsomely weathered from thousands of years of exposure.  A real ivory tusk, not a stone fossil, perfect for display rather than cutting uo, it "stands" on it's own like a bridge.  This one came out of the Yukon river in 2014.  Priced at only $4,750, includes shipping and insurance.
