The chunky facets turn light over in broad, slow flashes rather than fine sparkle. Cut in the antique manner, newly made, and set as a four-prong solitaire so the stone leads.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLab-grown diamond · D–F color · VVS+ clarity · IGI certified\u003c\/li\u003e\n\u003cli\u003eMade to order in 14K or 18K gold (yellow, white, rose)\u003c\/li\u003e\n\u003cli\u003eBand width: 1.8mm\u003c\/li\u003e\n\u003cli\u003eHand-finished, ships in 12–16 business days\u003c\/li\u003e\n\u003cli\u003eLifetime warranty · free resizing · 30-day returns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eIs this a real diamond?\u003c\/strong\u003e Yes. Lab-grown diamonds are chemically and optically identical to mined diamonds — same carbon structure, same 10 Mohs hardness, same fire. The only difference is origin.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does “cut in the antique manner” mean?\u003c\/strong\u003e The stone is a newly made lab-grown diamond faceted to old mine geometry — high crown, small table, chunky facets, and a large open culet that reads as a dark window at the center. It returns light in broad, slow flashes rather than the fine sparkle of a modern brilliant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is an elongated cushion different from a standard cushion?\u003c\/strong\u003e Proportion. A standard old mine cushion reads close to square; this stone is drawn to roughly 1.25:1, so it runs longer down the finger while keeping the same high crown and open culet.\u003c\/p\u003e","brand":"Sula Bridal","offers":[{"title":"14K Yellow Gold \/ 1.00ct","offer_id":43591179894990,"sku":null,"price":1700.0,"currency_code":"USD","in_stock":false},{"title":"14K
