First is Morbid Jewel:

This key was formed with overlapping hearts that spiral around each other and is decorated with a single mounted red jewel in the center. (^_^)
Next is Kokoro Cut:

Sharpened to a razor's edge and sporting an impaled heart on a spire, you may never get wound while wearing this one due to its sharp edges. (^_^)
