The antique gem is securely housed within a crisp, geometric hexagonal crown setting—a signature design technique of the period meticulously engineered to maximize the diamond's visual presence and contrast against the bright metal.\u003cbr\u003eThe mounting is a masterwork of delicate openwork, featuring exceptionally fine, die-stamped pierced filigree along the gallery and detailed hand-engraved scrollwork cascading down the shoulders. Crafted in premium 18-karat white gold, the ring exhibits a remarkably low-profile, comfortable sit on the finger, making it as wearable today as it was a century ago. A timeless heirloom perfect for a unique engagement ring or a signature addition to any antique jewelry collection.\u003cbr\u003eSpecifications\u003cbr\u003ePeriod: Art Deco, circa 1920–1930\u003cbr\u003eMetal: 18K White Gold (or Platinum, pending testing)\u003cbr\u003ePrimary Stone: Antique Old European Cut Diamond\u003cbr\u003eStone Weight: Approx. 0.30 carats\u003cbr\u003eQuality of diamond SI\u003cbr\u003eColor of diamond G – H\u003cbr\u003eDesign Elements: Hexagonal crown setting, pierced filigree gallery, hand-engraved shoulders\u003cbr\u003eCondition: Excellent antique condition with minimal wear consistent with age\u003cbr\u003eRing width 10.26 mm \u003cbr\u003eheight 5.55 millimeter\u003cbr\u003eShank 1.60 mm\u003cbr\u003eFinger size 3.25\u003c\/p\u003e","brand":"Legacy Jewelry Appraisers \u0026 Buyers","offers":[{"title":"Default Title","offer_id":67695550922930,"sku":null,"price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0089\/5064\/4793\/files\/730ED8A5-788E-490B-B717-2DB8E86CDA45.jpg?v=1792646883","url":"https:\/\/legacyjewelryoc.com\/products\/antique-art-deco-30-carat-old-european-cut-diamond-filigree-ring-in-18k-white-gold-circa-1920","provider":"Legacy Jewelry Appraisers \u0026 Buyers","version":"1.0","type":"link"}
