Elsa Peretti's timeless open heart pendant is instantly recognizable and highly desirable. Treat yourself to one for $145 at Tiffany & Co. (or drop hints to your significant other—these make great gifts!).


If you love the look but can't afford to splurge, pick up this slanted heart necklace instead, just $4.80 at Forever21.com. It won't last a lifetime but it'll do in a pinch.
