The ring showcases clean lines and a minimal profile that lets the gemstone shine. \u003cmeta charset=\"utf-8\"\u003eThe sapphire has been upcycled from an older, unrestorable piece and given a fresh polish. The result is a timeless solitaire with renewed brilliance and historical roots.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003eWhat we love about this piece is that the prongs are seamlessly part of the ring. A classic design with historical pedigree—Ostby \u0026amp; Barton (1879–1950, based in Providence, RI) was once one of the largest ring manufacturers in the U.S., and their early work remains highly collectible today.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cstrong\u003eRING\u003cbr\u003eMaterial:\u003c\/strong\u003e 14k yellow gold\u003cbr\u003e\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 4–1.3 mm wide \/ 4.8 mm high off finger\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.6 grams\u003cbr\u003e\u003cstrong\u003eMarkings:\u003c\/strong\u003e “O-B 14K” (Ostby \u0026amp; Barton maker’s mark)\u003cbr\u003e\u003cstrong\u003eRing Size:\u003c\/strong\u003e 7\u003cbr\u003e\u003cstrong\u003ePeriod:\u003c\/strong\u003e Circa 1890–1910\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cstrong\u003eSAPPHIRE\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.21 cts (exact)\u003cbr\u003e\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 3.2 mm\u003cbr\u003e\u003cstrong\u003eCut:\u003c\/strong\u003e Round faceted\u003cbr\u003e\u003cstrong\u003eColor:\u003c\/strong\u003e Dark blue\u003cbr\u003e\u003cstrong\u003eClarity:\u003c\/strong\u003e Eye clean\u003c\/p\u003e","brand":"The Vintage Vault","offers":[{"title":"Default Title","offer_id":50355096846650,"sku":"RG10066","price":320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/7398\/7898\/files\/victorian_sapphire_14k_yellow_gold_ring.jpg?v=1747222342","url":"https:\/\/petrastar.com\/ja\/products\/ostby-barton-victorian-sapphire-solitaire-ring-in-14k-gold-2","provider":"Petra Star","version":"1.0","type":"link"}
