Tumbled on the beach this piece have a rounded smooth surface.  The medium brown outside covers a lighter ivory color core. This  would be good for carving  into something wonderful or for handles. - 9 1/2" long x  2 1/4 x 1 15/16" " wide. Has a very thin outer layer separation ( see photos). A solid tusk section.

Excavated on St. Lawrence Island by Eskimo people known as Siberian Yupik. For over 5,000 years the Yupiks had villages along the Bering Sea and fashioned sled runners, net weights, chopping tools and other utensils out of readily available ivory. That ivory became hidden from the world for centuries, when it was discarded in the village middens (dumps) along with tusks and bones of walrus, whales and seals. Only now is that ancient ivory being unearthed, excavated by the descendants of the primitive Yupiks that worked it.
