At its heart is a double-sided swivel mount — riveted to rotate freely — that showcases a deep black onyx cabochon on one face and a luminous abalone shell on the other, each bezel set with quiet precision. Wear it mysterious with the onyx forward, or flip it to reveal a cascade of iridescent blue, green, and violet. Two moods. One ring. Entirely handmade.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe open, expandable shank adjusts comfortably starting at a size 7. The sterling silver has developed a natural patina over the years — an honest mark of age and authenticity that only deepens the piece's character. Marked 925 and clearly the work of a skilled studio hand, this ring embodies the spirit of the Modernist studio jewelry movement: thoughtful in construction, bold in presence, and built to be worn.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA rare find for collectors of wearable art, kinetic jewelry, or anyone drawn to pieces with more than one story to tell.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 4px 0;\"\u003e\u003cstrong\u003eRING\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin: 0 0 12px 0; padding-left: 0; list-style: none; line-height: 1.4;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e Sterling silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarkings:\u003c\/strong\u003e 925\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinger Size:\u003c\/strong\u003e 7 (open adjustable shank; expandable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 31.5 x 17.5 mm face \/ shank tapers 2.9–6.2 mm wide \/ 6.5 mm high off finger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 5.6 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Handmade; open adjustable shank; riveted rotating\/swivel stone mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin: 0 0 4px 0;\"\u003e\u003cstrong\u003eSTONES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin: 0 0 12px 0; padding-left: 0; list-style: none; line-height: 1.4;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack Onyx\u003c\/strong\u003e — Cut: Cabochon | Setting: Bezel | Color: Opaque black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbalone Shell\u003c\/strong\u003e — Type: Natural abalone | Setting: Bezel | Color: Iridescent blue, green, and violet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cstrong\u003eCirca:\u003c\/strong\u003e c. 1960s–1970s\u003c\/p\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Very good vintage; natural patina consistent with age\u003c\/p\u003e","brand":"The Vintage Vault","offers":[{"title":"Default Title","offer_id":53394969067834,"sku":"TR0228","price":135.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/7398\/7898\/files\/petra-star-modernist-swivel-ring-black-onyx-abalone-front.jpg?v=1777921535","url":"https:\/\/petrastar.com\/it\/products\/modernist-sterling-silver-swivel-ring-black-onyx-abalone-shell-rotating-double-sided-adjustable-open-shank-handmade-925","provider":"Petra Star","version":"1.0","type":"link"}
