Both elegant and pristine, this French Art Deco brooch centers on a scintillating .85 carat (VS1 / G-H) marquise-cut diamond bordered by seamlessly-set natural blue sapphires that flow into a gently graduated line of brilliant blue sapphires, framed in sparkling single-cut diamonds. Masterfully hand fabricated in platinum finished with migrain edges. Numbered with a partial maker's mark, possibly Lucien Secouet. A magnificent jewel.
