Snake yoga pose? We’re not sure if this serpent is trying to work out a kink or just showing off his flexibility. Whatever the intent, his weighty, intricately coiled, beautifully hand-engraved body creates a cool, curvy design to wrap around your finger. Even better, he’s from the diamond-headed, ruby-eyed species. Hand fabricated in 14K yellow gold, circa early-20th century, this Edwardian jewel is currently size 10.
