These are created by spiraling tubules that feed the ivory as it grows, and are unique to elephant ivory. They will be most visible on a cross section of the tusk, which in this case would be on the bottom edge of the tiger&#039;s head. On a tangential surface (parallel to the outer surface of the original tusk) they show more like wood grain. </p><p><br /></p><p>If you do a search for previous threads on ivory you will find several examples of ivory that illustrate the schreger lines.[/QUOTE]</p><p><br /></p>
