CRYSTAL CLEAR: Our favorite trend in spring and summer jewelry this year is clearly making waves. A total 180 from all the recent dark, gothic bling, light-catching transparent pieces are now all the rage. Whether you rock an armful of bangles, a statement necklace or a chunky cocktail ring like this beauty by Kenneth Jay Lane, make sure and mix in a little fantastic plastic. GET IT: Goldtone and Clear Ribbed Ring, $75. Available online from Macy’s.
