This piece is in the shape of a crescent-moon, embellished with prong-set clear rhinestones, crown-set blue glass cabochons; set in decorative bronze-coloured metal. It measures 5 3/4" in diameter x 1 3/4" at its widest. It has the appearance of a hair comb or tiara, but no prongs. Usually a sew-on applique has loops for attachment. Does not appear to have any broken pieces. Any help as to what this piece may be, its age or price would be appreciated!
