This is a three segmented ring to go over a finger joint. Each segment is hinged to the center ring. It has gold tone filigree with a 5/8” turquoise colored stone in the center. I do not know if it is real or faux so I am identifying it as Faux. The ring does have light wear at bottom where the gold tone has worn though to the copper metal. Still in great used condition. The ring fits a 6-1/2” ring size. The overall length is 2” and 1” width.
