A striking example of Art Deco-era craftsmanship, this 1920s platinum brooch features a vivid cabochon ruby at its center, surrounded by a dazzling array of old European brilliant-cut and baguette-cut diamonds. The geometric design and bold symmetry capture the essence of the Jazz Age, while the generous diamond weight and rich ruby hue exude timeless sophistication. This brooch was prominently styled on actress Sarah Snook for the 2025 Met Gala, adding a regal and historic flair to her ensemble and cementing this jewel as a standout vintage treasure on the red carpet.
