Featuring two vibrant crystals in shades of luminous green and astral pink, it's set on invisible prong settings with a gold-tone plated finish. The perfect gift for yourself, or a loved one. This keyring is part of the Curiosa family, designed by Creative Director Giovanna Engelbert for Collection II.
