A dense field of bezel-set round diamonds forms the central sweep, punctuated at regular intervals by step-cut square diamonds that add structure and contrast. The pattern tapers outward into linear gold sections set with additional diamonds, creating a balanced transition from ornate center to refined edges. Thoughtfully engineered with flexible links, the necklace sits fluidly while maintaining a bold, graphic presence, totaling approximately 13.55 carats of diamonds.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eWeight: 95.8 grams\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eStone: 13.55ctw Round and Step Cut Square Diamonds, G-H VS\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eLength: 18\"\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eMeasurements: 7.0 - 15.4 mm wide \u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eHallmark: 750 \u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eMetal: 18k Yellow Gold\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cspan style=\"color: rgb(0, 0, 24); background-color: rgb(255, 255, 255);\"\u003eItem: BR-1803-021426-05\u003c\/span\u003e\u003c\/div\u003e","brand":"Blue Ribbon Rarities","offers":[{"title":"Default Title","offer_id":41045288419400,"sku":"BR-1803-021426-05","price":24995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2223\/5059\/files\/DSC_5350_3100218.jpg?v=1771818322","url":"https:\/\/www.blueribbonrarities.com\/products\/vintage-18k-yellow-gold-13-55ctw-diamond-collar-necklace","provider":"Blue Ribbon Rarities","version":"1.0","type":"link"}
