Art Deco Diamond Platinum Bar Brooch

An estate Art Deco bar brooch (circa 1915) showcasing the era’s signature geometry and airy filigree/openwork look, set with Old European cut diamonds totaling an estimated 4.00 cttw in G–I color and VS1–SI1 clarity. The platinum and 14K yellow gold construction gives it a refined two-tone presentation that merchandises beautifully in antique/vintage cases, bridal-alternative stories, and occasion-driven gifting, with strong cross-sell potential alongside Art Deco rings and earrings.
