State Property's fine jewelry is inspired by everything from literature and architecture to nature and current events. Named after Tania Aebi, the first American woman - and youngest, at the time - sailor to sail solo around the world, this necklace is handmade from 18-karat gold and features a pear-cut diamond nestled in the center of glossy white enamel and a halo of 0.86-carat pavé ones.
