Scary, scary face bead 2

Continuing the scary bead series, here is a second face bead.

This second bead was purchased in Myanmar. I think it is made of glass. The face is not as expressive as bead 1 but it is striking in its own way. The lips are thick, I wonder whether this was what early Burmese man looked like. The head is bald, is it a monk ? There are numerous pits on the surface of the eroded glass. The hole mouth is not a perforation as the bead is perforated through the head. The sea green color seem to imitate jade.

Perhaps this bead is from the ancient Pyu kingdom ?
