Meticulously crafted in polished 14K white gold, the center stone is held in a secure six-prong setting that protects its delicate points while emphasizing its regal and slender profile. The design features a traditional cathedral shank, which architecturally lifts the diamond to a sophisticated height, creating a profile that is both structural and timeless. Tucked subtly beneath the marquise centerpiece is an intricate hidden halo featuring 18 small round lab-grown side diamonds totaling 0.13 carats, providing a luxurious secret sparkle that is visible from every side angle. Designed in a size 7, the minimalist, high-polished plain shank ensures that all focus remains on the impressive 2.87-carat centerpiece.","brand":"Kira Jewels Inc","offers":[{"title":"Default Title","offer_id":45608537522278,"sku":"KJ00790R.MQ-3-21F","price":6852.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/5842\/4934\/files\/ChatGPTImageJun5_2026_10_30_26AM_4_5345581a-e782-4b77-a023-6ed16d4aa4b7.png?v=1781497087","url":"https:\/\/diamondgallery.com\/products\/3-00-ct-marquise-cut-lab-grown-diamond-cathedral-shank-solitaire-ring","provider":"Diamond Gallery","version":"1.0","type":"link"}
