Positively creepy... but eerily beautiful. BloodMilk's gorgeous rings (and other bling) are made from cast body parts of small animals (like owls and bats). The ring above features a sterling silver setting cast from a sparrow's claw. The Sparrow Claw Ring Single ($120) by BloodMilk is finely constructed with just enough imperfection to compliment the interestingness of the animalistic feature, just like the two other rings below. The Conjoined Eagle Talon Ring ($235, left) and the 1000 Profound Virtues Hummingbird Skull Ring ($115, right) employ similar stunningly sinister aesthetics.
PS - Check out the great necklace too!
