The Wedjet; also known as the eye of Horus is a very powerful symbol in Ancient Egypt. It represents the "eye" of the Falcon (Horus) who represents the Sun. This wedjat most likely served as a talisman for protection which could also bring strength and prosperity. Most likely used in the funerary process and often placed on the deceased. From circa the Late Period and measures 3/4" length. Looks much better than the photo would indicate.
