This classic ring features a 2.5 carat lab-grown blue sapphire in gold-plated 925 sterling silver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes a GRA certificate.

From the side, finer accents beneath the setting and along the band add detail that is less obvious at first glance. That combination makes it a choice for someone who prefers the focus of a solitaire-style center but still enjoys ornament in the setting.\u003c\/p\u003e\n\u003cp\u003eWear it with a tailored jacket for an anniversary dinner, or pair it with simple sapphire studs for a family celebration. As a September birthday or anniversary gift, it suits a preference for deep blue and softly rounded shapes rather than a long oval or sharply rectangular stone. Choose a fixed US size from 5 through 9.\u003c\/p\u003e\n\u003ch2\u003eProduct details\u003c\/h2\u003e\n\u003cdl\u003e\n\u003cdt\u003eMain Stone\u003c\/dt\u003e\n\u003cdd\u003eLab-Grown Blue Sapphire\u003c\/dd\u003e\n\u003cdt\u003eCenter Stone Weight\u003c\/dt\u003e\n\u003cdd\u003e2.5 ct\u003c\/dd\u003e\n\u003cdt\u003eStone Cut\u003c\/dt\u003e\n\u003cdd\u003eCushion Cut\u003c\/dd\u003e\n\u003cdt\u003eStone Color\u003c\/dt\u003e\n\u003cdd\u003eBlue\u003c\/dd\u003e\n\u003cdt\u003eMetal\u003c\/dt\u003e\n\u003cdd\u003e925 Sterling Silver\u003c\/dd\u003e\n\u003cdt\u003eFinish\u003c\/dt\u003e\n\u003cdd\u003eGold-plated\u003c\/dd\u003e\n\u003cdt\u003eRing Sizes\u003c\/dt\u003e\n\u003cdd\u003eUS 5, 6, 7, 8, and 9\u003c\/dd\u003e\n\u003cdt\u003eStyle\u003c\/dt\u003e\n\u003cdd\u003eClassic\u003c\/dd\u003e\n\u003cdt\u003eWearability\u003c\/dt\u003e\n\u003cdd\u003eHypoallergenic\u003c\/dd\u003e\n\u003cdt\u003eDesign\u003c\/dt\u003e\n\u003cdd\u003eCushion center with clear shoulder and gallery accents\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.
