Vintage Van Cleef & Arpels 18K Platinum Sapphire Diamond Flower Brooch NUMBERED

An exquisite late-1950s floral brooch by the legendary French house Van Cleef & Arpels, crafted in 18K yellow gold and platinum. The dimensional blossom is set at the center with approximately 2.75 carats of vivid royal blue natural sapphires, framed by about 1.00 carat total weight of fine round brilliant diamonds graded F-G color and VS1 clarity. The piece bears triple VCA hallmarks, an individual serial number, and French assay marks for both platinum and 18K gold. A masterful example of Van Cleef & Arpels' mid-century craftsmanship and elegant organic design.
