{"product_id":"vintage-14k-white-gold-synthetic-star-sapphire-signet-ring","title":"Vintage 14K White Gold Synthetic Star Sapphire Signet Ring — Unisex, Circa 1970s","description":"\u003cp dir=\"ltr\"\u003eThis vintage piece, cast in solid 14K white gold and dating to circa the 1970s or later, carries that same architecture: a bold, high-polish dome rising from a substantial shank, weighing a full 10.8 grams — the kind of heft that announces itself on the hand rather than asking permission.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSet at its center is an oval cabochon synthetic star sapphire, deep royal blue and eye clean, its six-rayed star drifting across the surface with every tilt of the hand. That optical phenomenon — asterism — occurs when light reflects off needle-like inclusions of rutile arranged along the crystal's internal structure, and it is one of the more theatrical effects in all of gemology. Created corundum reproduces the same crystalline structure as its natural counterpart, and by the mid-20th century, laboratory-grown star sapphires had become genuinely beloved in their own right — prized for delivering a flawless, perfectly centered star with a saturation of color natural stones rarely achieve without treatment. Men's rings set with a bold synthetic star sapphire were a signature look of the era: worn as class rings, signet rings, and statement pieces that traded subtlety for presence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRING\u003c\/strong\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eMaterial: \u003c\/strong\u003e14k white gold\u003cbr\u003e\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 14.1 to 4.5 mm \/ height 6.8 mm\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 10.8 grams\u003cbr\u003e\u003cstrong\u003eMarkings: \u003c\/strong\u003e\"14K\"\u003cbr\u003e\u003cstrong\u003eRing Size: \u003c\/strong\u003e4.75 (can be sized)\u003cbr\u003e\u003cstrong\u003eCirca:\u003c\/strong\u003e 1970s or later\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSAPPHIRE\u003c\/strong\u003e \u003cbr\u003e\u003cstrong\u003eSource:\u003c\/strong\u003e Synthetic\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 11.6 x 9.6 x 4.19 mm\u003cbr\u003e\u003cstrong\u003eCut:\u003c\/strong\u003e Oval cabochon\u003cbr\u003e\u003cstrong\u003eColor: \u003c\/strong\u003eDeep royal blue\u003cbr\u003e\u003cstrong\u003eClarity: \u003c\/strong\u003eEye clean\u003cbr\u003e\u003c\/p\u003e","brand":"The Vintage Vault","offers":[{"title":"Default Title","offer_id":50373141561658,"sku":"RG10090","price":1790.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/7398\/7898\/files\/vintage-14k-white-gold-synthetic-star-sapphire-signet-ring-unisex-circa-1970s-1278112.jpg?v=1789222927","url":"https:\/\/petrastar.com\/it\/products\/vintage-14k-white-gold-synthetic-star-sapphire-signet-ring","provider":"Petra Star","version":"1.0","type":"link"}
