This is a vintage tribal art pendant from Persia / Iran. I was given it in 1965 by the father of an Iranian scholar. It has never been cleaned and has been stored for decades. Wears beautifully. I wore it with a ribbon high on the neck. The mosaic of all colors of turquoise from the mines in Iran. The inlaid symbol seems to mark the 4 elements and the center, or directions. The backing looks like brass or bronze and was hand-cut.
