Silversmith Polly van der Glas makes jewelry you can really sink your teeth into. The artist collects human teeth, hair and fingernails, sterilizes them, and incorporates them into silver jewelry. These toothy trinkets and hairy ornaments fetch a hefty price on van der Glas’ Etsy store, but the artist says her pieces are more than just jewelry. She wants her work to explore the fact that teeth, hair and nails were all once part of a beauty ritual, but when they become detached from the body, their meanings are transformed. Whether you find van der Glas’ work to be beautiful or disturbing, one thing is for sure: Stealing from the Tooth Fairy sure is greener than mining for precious stones.
