This generously cut matinee length aged brass necklace (24") is just perfect for year round wardrobes, with a small chocolate brown crystal, set in a delicate matching brass setting. Long necklaces are in for 2012, and look great layered or on their own! Paired with your crystal is a matching brass safety pin charm, that really works, and is stamped with the word "elements." The focal charm was cut from one of our vintage library cards, this one on the theory of relativity, and it includes the famous equation by Einstein, E=MC2. Sparkly yet neutral to go with everything in your closet. A great gift for the one you love who loves books and science!

Due to the vintage nature of our library card collection, this piece is one of a kind and cannot be repeated.

This listing is for ONE (1) Dewey necklace with E=MC2 charm. Chain is 24" long, with brass lobster clasp and matching hardware.

Need a larger amount? Feel free to contact me directly! Very cool gift for the librarian, bibliophile, or geek in your life! Awesome gifts for new graduates of MLS and MLIS programs! Peridot is the birthstone for August, so it's a fantastic August birthday present as well!

I use a water resistant epoxy, but since one element of this necklace is paper, you should remove it before bathing or swimming.
