Hello All,
I bought these ????? as beads in Ebay , however, no hole - no bead, so I got a refund and could keep the things. It looks like amber but has very few gold flecks in it. So I think it is plastic. But the pieces are old old and one side have some sticky substance on parts as if it had been inserted into ????. At a quick look it looks like manmade teeth. Does anybody have an idea what that could be? What it could be made of? Where it comes from? Any suggestions are welcome!

Could I have holes drilled?

Thanks
Anne
