Pomellato's Nudo collection has always been about the gems, first launched in 2001, its almost invisible setting put the stone front and centre, allowing it to capture the light from every available angle. In the case of these drop earrings, a blue London topaz is subjected to this signature cut, with its softly rounded shape and multifaceted face making for a welcome contrast against the smooth 18-karat rose gold of the hooped clasp.
