This classic Art Deco jewel presents many of the characteristic design elements of the era in one modestly sized—and striking—brooch. A carved frosted rock crystal plaque, shining at its center with a marquise diamond, glitters around its perimeter with lively single-cut diamonds punctuated by pairs of baguettes. In bold and dramatic contrast, this white-on-white composition rests atop a scallop-edged glossy black onyx plaque, creating a dynamic dash of Jazz Age chic for your ensemble. Total diamond weight, 1.00 carat. Hand fabricated in platinum, circa 1920 (pin stem and mechanism are 14K white gold). \u003c\/p\u003e","brand":"Lang Antiques","offers":[{"title":"Default Title","offer_id":53914398556488,"sku":"50-1-11407","price":2895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/2122\/3496\/files\/art-deco-onyx-rock-crystal-and-diamond-brooch_2_50-1-11407.jpg?v=1787827120","url":"https:\/\/langantique.com\/products\/art-deco-onyx-rock-crystal-and-diamond-brooch","provider":"Lang Antique","version":"1.0","type":"link"}
