Perfect for best friends who bring out the best in each other, these pendant necklaces are opposites, but complementary. One necklace is more rugged and simple, with a black cord necklace and a plain, brushed silver half-heart. The other necklace is more classic-chic with a shiny silver chain and rhinestone-embellished half-heart. Even if you and your best friend aren't exactly alike, you can still rock the fashionable best friend look.
