This Turkoman disk was collected in Persia, namely in Gonbad-e-Kabus, which is situated in Golestan near the southeast corner of the Caspian Sea and in the heart of Yomud territory. If you look at the back, the piece has four places for attachment, so the ornament could have been made for the bridle of a horse, or for someone’s belt, or to serve as decoration sewn onto clothing.
