Rectangular Art Deco Brooch In 18-karat Gold And Silver, Set With Old-cut Diamonds

Art Deco rectangular brooch in 18-karat gold and silver, set with old-cut and rose-cut diamonds – France, circa 1920. A superb geometric brooch from the Art Deco period, crafted in silver over 18-karat gold, testifies to the refined craftsmanship of French workshops in the 1920s. The jewel has an elongated rectangular shape, with a rigorously symmetrical design, entirely pavé-set with diamonds in a checkerboard pattern. The composition comprises 84 stones, arranged in six rows of fourteen diamonds, set with perfect regularity. The central diamonds are all full-cut old-cuts, chosen for their generous brilliance and deep fire, while the outer row is composed exclusively of more discreet rose-cut diamonds, whose diffused sparkle delicately highlights the contour of the piece. This contrast between old-cut and rose-cut diamonds creates a subtle interplay of light and texture, characteristic of jewelry from the transition between the Belle Époque and pure Art Deco. An exquisitely elegant brooch, both understated and precious, with exemplary craftsmanship, ideal for adorning a jacket lapel or evening gown with distinction.
