In Egypt, the heart amulet was considered to be among the most important of all amulets as the heart was the most essential organ. People believed it was the center of feelings, conscience and intelligence; this is why it was weighed in the balance in the underworld to ascertain whether its owner was worthy to enter.
This amulet is made of blue faience to imitate the semi-precious stone, lapis lazuli, which is blue, and is a symbol of the blue of the Nile's reviving waters.
It is in the form of an egg-shaped vessel, and like most heart amulets, it was found on a mummy in the area of the upper torso and was placed there to endow the deceased, by assimilation, with its particular function. It could also act as a substitute in the underworld in case the real organ was damaged or destroyed.
