This Art Deco-inspired ring features a 4 carat emerald-cut lab-grown sapphire, measuring 10 × 8 mm, in gold-plated 925 sterling silver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes a GRA certificate. Backed by a 2-year warranty.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe design builds outward in ordered rows: straight-edged cubic zirconia accents sit between fine clear borders, echoing the center's step-cut geometry. That symmetry and the stepped arrangement give the ring its architectural character. Emerald-cut refers to the sapphire's cut, and Art Deco-inspired describes the design rather than an antique origin.\u003c\/p\u003e\n\u003cp\u003eChoose it when you want a colored statement ring with strong lines instead of a rounded halo. A tailored suit or plain cocktail dress leaves room for the broad setting at an anniversary dinner or formal celebration. As a September birthday or anniversary gift, it suits someone who prefers deep blue and structured jewelry. Fixed US sizes 5 through 9 are listed.\u003c\/p\u003e\n\u003ch2\u003eProduct details\u003c\/h2\u003e\n\u003cdl\u003e\n\u003cdt\u003eCenter Stone\u003c\/dt\u003e\n\u003cdd\u003eLab-Grown Blue Sapphire\u003c\/dd\u003e\n\u003cdt\u003eCenter Stone Shape\u003c\/dt\u003e\n\u003cdd\u003eEmerald Cut\u003c\/dd\u003e\n\u003cdt\u003eCenter Stone Weight\u003c\/dt\u003e\n\u003cdd\u003e4 Carats\u003c\/dd\u003e\n\u003cdt\u003eCenter Stone Size\u003c\/dt\u003e\n\u003cdd\u003e10 × 8 mm\u003c\/dd\u003e\n\u003cdt\u003eAccent Stones\u003c\/dt\u003e\n\u003cdd\u003eCubic Zirconia\u003c\/dd\u003e\n\u003cdt\u003eAccent Shape\u003c\/dt\u003e\n\u003cdd\u003eTrapezoid\u003c\/dd\u003e\n\u003cdt\u003eMetal\u003c\/dt\u003e\n\u003cdd\u003e925 Sterling Silver\u003c\/dd\u003e\n\u003cdt\u003ePlating\u003c\/dt\u003e\n\u003cdd\u003eGold-plated\u003c\/dd\u003e\n\u003cdt\u003eAvailable Ring Sizes\u003c\/dt\u003e\n\u003cdd\u003eUS 5, 6, 7, 8, and 9\u003c\/dd\u003e\n\u003cdt\u003eWear\u003c\/dt\u003e\n\u003cdd\u003eHypoallergenic\u003c\/dd\u003e\n\u003cdt\u003eStyle\u003c\/dt\u003e\n\u003cdd\u003eArt Deco-Inspired\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003ch2\u003eCare and support\u003c\/h2\u003e\n\u003cp\u003eRemove before exercise, cleaning, or tasks that could strike the setting.
