Known for a restrained luxury and often returning to brightly coloured stones inset into glistening metal, Monica Vinader's Siren collection adds fluid forms inspired by sea treasures to your edit. This larger version of its Siren ring is resplendent with a faceted green onyx at the centre, upping the contrast with 18 carat gold plating for a seductive look. The very definition of a statement, complete it with a matching Siren necklace when the clock strikes six.
