The smooth, highly polished black onyx is beautifully framed by sculptural openwork shoulders, each featuring a series of distinctive diamond-shaped cutouts that lend the ring an airy, architectural quality. The bold contrast between the rich black onyx and warm gold perfectly embodies the sophisticated geometry of the Art Deco era.\u003c\/p\u003e\n\u003cp\u003eEmerging during the 1920s, the Art Deco movement embraced clean lines, geometric motifs, and innovative openwork designs inspired by modern architecture and industrial progress. Black onyx became one of the period's most celebrated gemstones, admired for its sleek, mirror-like surface and dramatic visual impact. Jewelers often incorporated pierced and geometric galleries into their creations, allowing light to pass through the metalwork while emphasizing the precision and symmetry that defined the era's revolutionary aesthetic.\u003c\/p\u003e\n\u003cp\u003eBold, sculptural, and unmistakably sophisticated, this ring is a beautiful example of authentic Art Deco craftsmanship. The substantial cabochon onyx, paired with its beautifully pierced diamond-shaped open shoulders, creates a timeless statement piece that feels as modern today as it did a century ago. A remarkable addition to any antique jewelry collection, it captures the enduring glamour and innovative design of the Jazz Age.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eBrand\/Maker: Unknown\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eEra: 1920s\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eMaterial(s): 14k Gold\/Onyx\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eMarkings\/Stamps: 14k\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eMeasurements\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eSize: 6.5\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eStone: 18.1mm x 12.9mm\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eProfile: .5\"\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eTotal Weight: 7.63g\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eCondition: Excellent\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eCall Outs: \u003c\/span\u003e\u003cspan\u003eNone\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eSku: KO15\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Kate O.","offers":[{"title":"Default Title","offer_id":46248699068602,"sku":"KO15","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/9124\/9082\/files\/IMG_0129.jpg?v=1787240359","url":"https:\/\/thisandthatvintage.com\/products\/ko15-1920s-14k-gold-art-deco-open-shoulders-with-diamond-design-cocktail-ring-with-large-cabochon-onyx-center-stone-3941","provider":"This \u0026 That Vintage","version":"1.0","type":"link"}
