Interesting! I was thinking some sort of ivory piece.
I don't think it's ivory. Maybe faux ivory or some sort of synthetic.
I tried the hot pin test but couldn't melt a hole in it. That's not saying much since I had to heat the pin on an electric stove and wasn't sure it got hot enough.
The first picture is a close up of the visible grain and the second picture I got off the internet and it was identified as laminated bone. Doesn't really look like the same grain.
I've read that regular parallel grain is indicative of synthetic material.
Anyway, I'm not much concerned with what it's made of as much as where it came from, who made it, when it was made, and if there are other examples somewhere.
For all I know they could have been turned out by the thousands and sold to tourists for 5 bucks in a bazaar someplace.
Or someday I'll go on the Antiques Roadshow and get told they are worth hundreds of thousands.
