Pamela Love definitely has a goth/dark/industrial vibe to her jewellery. She did pieces as a tie-in with Where the Wild Things Are, and her collections feature worked, twisted metal, skulls and claws, and religious references. (Loved the talon rings on her splash page.)
These sacred heart necklaces are quite large, a twist on the expression “wear your heart on your sleeve”. She is widely sold online and in bricks and mortar stores. See more of her work on her website.

She sure makes quite a statement with her pieces.
