Carolina Bucci 18-Karat Yellow Gold Florentine Finish Heart Ring. The “Florentine” Finish is a signature collection for Carolina Bucci and today even more associated with the brand following her designs for Audemars Piguet. The “Florentine” finish is an effect achieved by beating the gold with a diamond-tipped tool which leaves permanent faceted dents in the gold. These indentations give the pieces their sparkly texture.
