It's possible to be some sort of thermoplastic and a hot pin would melt/damage it leaving a mark. If it's bone of ivory it shouldn't leave a mark. In that case those are fairly easy to tell apart - bone has blood vessels through out so it has small pores you can see esp under magnification. OTOH ivory has the famous "Schreger lines".
Let us know the outcome!
