Its presence is refined and controlled, centered on a deep blue sapphire set within a raised prong mount.\u003c\/p\u003e\n\u003cp\u003eThe sapphire draws the eye without excess. Its faceting produces a darker, tonal light—subtle rather than sharp—offering depth and quiet movement as it turns.\u003c\/p\u003e\n\u003cp\u003eThe structure is where the piece distinguishes itself. Open filigree runs through the gallery and shoulders, reducing visual weight while preserving strength. Every element is considered, resulting in a ring that feels both delicate and composed.\u003c\/p\u003e\n\u003cp\u003eUnbranded, yet entirely consistent with American Art Deco construction in both material and form.\u003c\/p\u003e\n\u003ch2\u003eAt a Glance\u003c\/h2\u003e\n\u003cp\u003eArt Deco sapphire ring — 18K white gold\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCirca 1920s–1930s\u003c\/li\u003e\n\u003cli\u003eNatural, round blue sapphire\u003c\/li\u003e\n\u003cli\u003eApprox. 4.5 mm\u003c\/li\u003e\n\u003cli\u003e18K white gold\u003c\/li\u003e\n\u003cli\u003eOpen filigree gallery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaker:\u003c\/strong\u003e Unknown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K White Gold (tested)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEra:\u003c\/strong\u003e Circa 1920s–1930s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Stone:\u003c\/strong\u003e Blue Sapphire (Round Cut)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated Size:\u003c\/strong\u003e ~4.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated Carat Weight:\u003c\/strong\u003e ~0.28 ct\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Raised Prong Solitaire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Size:\u003c\/strong\u003e 5.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.92 grams\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDetails\u003c\/h2\u003e\n\u003cp\u003eAn authentic Art Deco ring defined by proportion, restraint, and structural clarity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Stone\u003c\/strong\u003e\u003cbr\u003eA deep bluetone with darker saturation and natural tonal variation.
