Octo Necklace

Octo Necklace - Black Acrylic, originally uploaded by studiohalo.

This octopus necklace in black acrylic is amazing - the only way is could be any better is if its tentacles were holding the chain, as apposed to being "drilled".

They have many others, so check 'em out at Flickr (just clic-the-pic) and there is an Etsy.com store, but at the time of writing is closed for a break - so check back often.
