Chicago jewelry designer Peggy Skemp's heart locket is an anatomically correct human heart—inside and out. Made of recycled sterling silver, the locket literally lets you wear your heart out. The chain is strung through the superior vena cava and left pulmonary vein, and the trunk of the aorta snaps the locket shut. Available for $275 through the designer's website, it's the perfect gift for anyone who is tired of endless generic ways to say "I love you". You can't beat it. Literally!
