The Fan Brooch — Blue Sapphire & Diamond

Unfurling like a moment frozen in time, this show-stopping fan brooch features 33.33 carats of vivid royal blue sapphires graduating to 15.12 carats of soft light sapphires — all set in a seamless invisible setting that lets the stones command every eye. At the pivot, 0.72 carats of brilliant white diamonds catch the light, finished in 18K white gold for a piece that is equal parts wearable sculpture and collector's treasure.
