This was originally a round cross-section of tusk. It cracked through the middle, so I broke it in half and polished up this nice half-circle. Stupidly I forgot to photograph the side view (duh) but it's about 3/8 of an inch thick. The markings you see around the rounded edge are "Schreger Lines." This is the cross-grain of the ivory tusk, I did not create that pattern.

Pictured below is an extreme closeup. The area shown is about 3/8 of an inch wide. Like what you see? I do custom work. :-)
