Description
French Late Art Deco Platinum & Diamond Brooch, ca. 1945 — 3.90ctw

An exquisite French brooch from the late Art Deco period, crafted in platinum with a white gold pin. The elongated plaque form is richly set with transitional cut diamonds, framed by fine milgrain detailing and executed with the precision and symmetry characteristic of the 1930s–40s.

  • Platinum brooch with white gold pin, French dog’s head hallmark
  • French lozenge-shaped maker’s mark (partial, unidentified)
  • Dimensions: approx. 2.63" (66.7mm) x 0.77" (19.65mm)
  • Weight: 13.7 grams
  • Transitional cut diamonds totaling approx. 3.90ctw
    • Average grade: H color, SI1 clarity
    • Center diamond: I color, I1 clarity, approx. 0.45ct (included in total weight)
  • Elegant milgrain edging throughout
  • Excellent original condition
Dating to around 1945, this brooch captures the last flourish of the Art Deco era, where strong geometric lines softened into more fluid, transitional designs. The precision-cut diamonds sparkle brilliantly in their platinum mount, enhanced by the delicate millegrain work. French craftsmanship of this period is especially prized, and the presence of the dog’s head hallmark confirms platinum fineness.

A sophisticated jewel in remarkable condition, ideal for collectors of Art Deco and French estate jewelry.
