This particular stone exemplifies the distinctive characteristics that make Old Mine Cut diamonds highly sought by collectors and jewelry enthusiasts—a cutting style that predates the modern Brilliant Cut and showcases a unique interplay of light and shadow. The faceting pattern creates a warm, romantic glow that distinguishes Old Mine Cut stones from their contemporary counterparts, making each piece a window into the gemological preferences and technical capabilities of the 1920s era. Set in 18-karat white gold by The White Rose Jewelry Mfg. Co., this diamond is complemented by the maker's signature deeply carved floral motifs—such as delicate pansies—that flow continuously around the band. The combination of the Old Mine Cut diamond's inherent character with the meticulous hand-finishing of the Art Deco setting creates a ring of exceptional historical and aesthetic significance. Marked authentically with \"18K PATD WHITE ROSE,\" this piece offers both documented provenance and the timeless appeal of a gemstone that has captivated collectors for over a century.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eMetal: 18K White Gold\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eGem: Old Mine Cut Diamond .40 Carats, G in Color, SI2 in Clarity\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eGem Measurements: 3.5 mm, Round\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eRing Size: 5.50\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eMarks: \"18K PATD WHITE ROSE\" Stamped on the inside band\u003c\/span\u003e\u003c\/p\u003e","brand":"Market Square Jewelers","offers":[{"title":"Default Title","offer_id":42761858908254,"sku":"A85138","price":3285.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1401\/8791\/files\/9223-004.jpg?v=1784729539","url":"https:\/\/www.marketsquarejewelers.com\/es\/products\/old-mine-cut-diamond-solitaire-white-gold-art-deco-engagement-ring","provider":"Market Square Jewelers","version":"1.0","type":"link"}
