The design is strongly geometric, centered by a diamond set within a square motif and surrounded by layered architectural panels. Old European–cut and single-cut diamonds are arranged throughout in pavé and linear settings, creating depth and symmetry across the shield form. Calibré-cut sapphires provide sharp blue accents, placed in vertical channels and along select edges to emphasize contrast and structure. Executed in platinum with fine milgrain detailing, the brooch exemplifies classic Art Deco craftsmanship and balance, with an impressive scale and crisp silhouette.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eWeight: 13.5 grams\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eStone: 4.54ctw Diamonds GH SI, .48ctw Blue Sapphire\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eMeasurements: 39.2 x 33 x 5.1mm\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eHallmark: \u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eBrooch Metal: Tests as 75-80% Platinum\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003ePin Metal: 13k White Gold\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"background-color: rgb(255, 255, 255); color: rgb(0, 0, 24);\"\u003eItem: BR-1771-122225-11\u003c\/span\u003e\u003c\/div\u003e","brand":"Blue Ribbon Rarities","offers":[{"title":"Default Title","offer_id":41044462174280,"sku":"BR-1771-122225-11","price":6495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2223\/5059\/files\/DSC_4954_3079107.jpg?v=1771548487","url":"https:\/\/www.blueribbonrarities.com\/products\/art-deco-platinum-4-54ctw-diamond-and-sapphire-shield-brooch","provider":"Blue Ribbon Rarities","version":"1.0","type":"link"}
