She sells seashells by the seashore, but we prefer to accessorise with them instead! These seashells are made from 9ct yellow gold with leverback fastenings to securely hold them in place in the ear. Measuring 1.3cm high, 0.6cm wide and 0.1cm wide, the earrings are stamped with a 375 metal mark and weigh just less than half a gram as a pair.
