Not having a pair of bedazzling basics like these in your jewelry wardrobe is like not having a little black dress, a navy suit and a pair of jeans in your closet! For that's how versatile and timelessly elegant they are-just as appropriate with yoga wear or office attire as they are with after-five sequins. And now our lab-grown DiamondAura™, with refractory index and color dispersion actually superior to mined diamonds, makes the classic 4-prong stud as easy on the purse as it is on the eyes. Set in sterling silver with post backs, each 5mm round DiamondAura weighs 1/2 carat, for a sum total of one carat.
