Claddagh By Night Red Crystal Heart Ring by Alchemy Gothic. A Claddaugh ring with a twist: instead of hands holding the genuine red Swarovski crystal heart, it's bony skeleton hands. The crown atop the crystal heart also has a tiny skull on it. Love, Friendship and Loyalty vouchsafed from the underworld, in the ancient Irish tradition. Height: 18mm (0.71") Width: 26mm (1.02") Depth: 29mm (1.14"). Made of lead-free fine English pewter exclusively by Alchemy Gothic.
