A red sweater on Valentine's Day asks for one bright thing at the neckline, and an open heart outlined in crystals does the job. The pendant hangs from a gold-tone curb chain and catches the light each time you turn your head. A clasp and extender chain let you set the length anywhere from 18 to 21 inches, so the heart lands just where you like it on a crew neck or a V.

This necklace from COCO + CARMEN stays in the rotation long after the holiday, over a white blouse, under a soft cardigan or at the open collar of a denim shirt.
