The details
Black and white diamonds fill a polished heart on this sterling silver necklace, a high-contrast pendant that still feels romantic. The sterling silver carries a rhodium finish, which gives the piece a bright, silver shine that sets off the dark stones. The heart hangs from a fine box chain through a small bail, and a spring ring clasp closes it, with an extender so you can adjust how it sits. Wear it over a crisp white shirt or a black knit, where the stones stand out against the fabric. A thoughtful choice for someone you love on Valentine's Day.
