This is a seller on Etsy that I just adore: OctopusMe
Just look at the things they sell:
The octopus jewellry appeals to the Innsmouth fan in me, I absolutely adore them... The look like somehting you might see adorning some monstrous Lovecraftian royalty rising from the depths.
Everything is made from real octopus and cast in sold sterling silver. And I just learned she's happy to do wedding bands, so there you go!
Want to give me a really pricy gift? ;) Then you know what's on the top of my wishlist.
