I love gothic style jewelry, not only for Halloween, but little gems like this, that are so pretty (and unusual) you'll want to wear them all year round.
I found these on the Charmed In New England site, along with lots of other goodies.
I love this PASSION bracelet, it's a tangled cuff of bloody thorns encrusted with red Swarovski crystal drops.
This little beauty retails for $169.99 when you purchase the matching earings and necklace.
