Silas' Tombstone

Silas' Tombstone is purportedly the world's first tombstone, according to occult expert Atticus Shane, and it is one of the keys to raising Silas. It is also considered extremely valuable in some witch circles, worth even more than the Hope Diamond, as it contains Qetsiyah's calcified blood, making it a powerful source of magic. It was first seen in the episode We All Go a Little Mad Sometimes, when Shane displayed it at an exhibit held at Mystic Falls High School.
