{"product_id":"art-deco-platinum-ruby-sapphire-diamond-day-night-flip-ring","title":"Art Deco Platinum Ruby, Sapphire \u0026 Diamond Day \u0026 Night Flip Ring","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eA rare and wonderfully clever Art Deco \"Day \u0026amp; Night\" flip ring, crafted in platinum throughout. The central band is calibré-set, half with rich royal-blue sapphires and half with pinkish-red rubies, while two hinged half-eternity bands of millegrain-set diamonds swivel on either side — so the ring can be worn with either the sapphires or the rubies at the centre of the two diamond bands, blue by day and red by night. Worn sideways, the hinges even fall into a zigzag across the finger.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eAlso known as a \"Night \u0026amp; Day\" or flip-over ring, this ingenious design dates from the 1920s, when such versatile, mechanical jewels were at their most fashionable, and genuine examples are increasingly hard to find. Beautifully made and endlessly wearable — three rings in one — it is a real collector's piece, and a joy to own.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMetal: Platinum\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStones: calibré-cut sapphires and rubies to the central band; millegrain-set diamonds to the two hinged bands\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDesign: \"Day \u0026amp; Night\" flip-over ring; two diamond half-eternities hinged either side of a ruby-and-sapphire centre\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMechanism: both swivel hinges in good working order\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRing size: M (UK) — cannot be resized, owing to the construction\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight: 7.23g\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCondition: Very good, with wear consistent with age; stones intact\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEra: Art Deco, circa 1920–1930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spectrum Antiques","offers":[{"title":"Default Title","offer_id":65406800855389,"sku":"SAO192","price":2250.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/0471\/3053\/files\/11-02-26Lightbox-1486copy.jpg?v=1785318502","url":"https:\/\/www.spectrumantiques.com\/products\/art-deco-platinum-ruby-sapphire-diamond-day-night-flip-ring","provider":"Spectrum Antiques","version":"1.0","type":"link"}
