{"product_id":"vintage-platinum-trillion-cut-diamond-semi-mount-engagement-ring","title":"Vintage Platinum Trillion Cut Diamond Semi Mount Engagement Ring","description":"\u003cdiv\u003eTwo trillion cut diamonds flank an empty center setting, giving this vintage platinum engagement ring a crisp, geometric composition. The diamonds’ triangular outlines point outward toward the shoulders, creating a balanced transition from the square center mounting to the tapered shank. Each side diamond is secured by three prongs, leaving its faceted surface prominently displayed. Four substantial corner prongs frame the central opening, while an open basket gallery reveals the setting’s construction beneath.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eWeight: 5.1 Grams\u003c\/div\u003e\u003cdiv\u003eSemi-Mount Opening: 7 × 7mm\u003c\/div\u003e\u003cdiv\u003eStone: 0.64ctw Trillion Cut Diamonds\u003c\/div\u003e\u003cdiv\u003eMeasurements: 22 × 8 × 6mm\u003c\/div\u003e\u003cdiv\u003eSize: 4.75\u003c\/div\u003e\u003cdiv\u003eHallmark: PLAT\u003c\/div\u003e\u003cdiv\u003eMetal: 940 Platinum\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eItem #: BR-2019-092926-05\u003c\/div\u003e","brand":"Blue Ribbon Rarities","offers":[{"title":"Default Title","offer_id":41418812293192,"sku":"BR-2019-092926-05","price":1495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2223\/5059\/files\/EmptyName_1377-A_4292071.jpg?v=1792176601","url":"https:\/\/www.blueribbonrarities.com\/products\/vintage-platinum-trillion-cut-diamond-semi-mount-engagement-ring","provider":"Blue Ribbon Rarities","version":"1.0","type":"link"}
