Hmm.. animal teeth--not as weird. To me, that's just like using bone.
Her daughter's tooth: now that's a little disturbing! Especially how they shaped it into a thistle! I wonder what the design discussion for that piece was like...
I saw the picturs. If you don't think about it, it kind of looks like mother-of-pearl.
I guess in those days they didn't do the whole tooth fairy thing.
And as for the animal teeth, it's a bit odd to see so many of them at one time, but nowadays they're still selling shark tooth neckaces. (Granted, they've been fossilized, but it's still a tooth from a shark.)
And, um, you don't kill a shark to get the tooth. Sharks have several rows of teeth that are constantly being replaced.
