As the heart charms on this pair of 13mm hoop earrings have a hammered finish, they have an enchantingly abstract surface that creates a gentle, twinkly sparkle as they move. The charms measure just 12mm tall x 7mm wide x 1mm deep and are threaded along a delicate pair of 13mm sleeper hoops. Both components of these earrings are constructed from 9ct yellow gold and therefore carry 375 metal stamps.
