Every woman knows that the right basics will complete a jewelry wardrobe. A classic pair of solitaire earrings. An everyday watch. A chic set of cultured pearls. A sparkling tennis bracelet. But don't forget the jewelry that defines a look. A vibrant gemstone ring. Signature hoop earrings. A statement necklace that makes a plain dress extraordinary. A stack of shimmering bolo bracelets or rings. These are the jewelry must-haves that will really dazzle.
