Hardangervidda Norway National Park Pin-Bone? Help/thoughts appreciated!

[clearsphere]

Hardangervidda Norway National Park Mountain Plateau Souvenir Pin measures 1 1/4” by 1 1/2” across. The back has excess shellac, otherwise in good vintage condition. Help/thoughts on material appreciated-as always!

Could be Antler too but hard to tell from pictures.

It looks like bone to me.

Thanks for comments, I wonder if a certain material would be more likely given the origin of Norway.

Could it possibly be Reindeer antler?
