Antique Art Deco Platinum Old European Cut Diamond Filigree Bar Brooch 3.70ctw.

This original Art Deco bar brooch is a striking example of 1920s craftsmanship, executed entirely in pure platinum. The piece is hand-set with approximately 3.70 carats total weight of old European cut diamonds that range F to H in color and VS1 to SI1 in clarity. Each diamond is individually nestled within delicate filigree and milgrain detail, forming a graceful geometric composition emblematic of the period’s elegance. Measuring 2.75 inches long by 0.45 inches wide and weighing 10.7 grams, the brooch retains its original platinum pin fitting and exemplifies the sophistication and refinement that define the Art Deco era.
