Coral Series Necklace
Nervous System makes some amazing biologically inspired jewelry.
Simple silver style with a hint of sparkle. I'm a fan of this Etsy jewelry designer. Be sure to check out her re-purposed pocketwatch necklaces too. Fab!
I hardly think you have to be Steampunk to wear this golden locket embellished with an octopus and tiny pearl. Keep your favorite photo of crazy Captain Nemo inside.
Simple octopus necklace from CreationsbyJuliann on Etsy.
For the sea lover and ring lover - you won't go wrong.
