This wisdom tooth was cast and polished and oxidized here in NYC.  I made the hole fairly big so you can also thread it onto your own chain as well.

The solid, blackened, .925 sterling pendant comes on a 18" inch long chain.

I also offer this wisdom tooth cast in white bronze and sterling, see it here.

The Story :
So as you might imagine I meet all kinds of quirky people on here.  I tell my stories and I guess that opens the door.  
There are some of us who like to pick treasures up from the roadside or the desert.  We are used to people and their judgments.  We have road kill in the freezer anyway. 

So I made a friend in Australia and she is of the same ilk.  She's a picker and collector of nature bits like me.  She managed to somehow get her own actual wisdom teeth through the mail to me.  My lady was shocked at the sight of the real teeth.  The folks at the casting house were grossed out too.  Me and my Aussie friend... we're psyched. I thought you might be too.
