When Simona Rosato dreamed up her latest batch of charm-festooned bracelets, she had fragrance on her mind. The Italian jewelry designer started with the idea that jewelry could hold onto a wearer’s perfume like cashmere scarf or a fur coat. The result of her erfforts is Joy, a line of charm bracelets and necklaces that absorb a fragrance and emit its bouquet for days. “I wanted to make jewelry that could be personalized, not just by what charms you choose, but by adding your perfume,” she says. Joy’s charms are able to retain scent through a new type of porous resum used to decorate the pendant. The resin is antiallergic and works best when spritzed with a fragrance minutes before being worn. The vividly hued charms run the gamut from cute (cherries, frogs and ice cream cones) to sporty (baseball caps and soccer balls) to good luck talismans (ladybugs and fourleaf clovers). Crafted from yellow or white gold, prices start at $300.
