Just some observations... I've seen many, many utchats and this is the first one with the suspension hole in this direction. The detailing is the same on both sides; thus, it can be used as an eye of Horus or an eye of Ra. The
faience is reticulated (open
work), usually a sign of
quality. From the remaining color of the glaze, I would say probably Third Intermediate Period or Later. If you were adventurous, like me, I would soak it overnight in Efferdent, the denture cleaner, it may remove most of the calcium (?) deposits on it.
