Vintage Jewel Blue Crystal Enamel French Barrette Hat Scarf Clip Brooch

I pulled this off a vintage hat headband.  It appears to have "teeth" for placement stability in addition to the clip. Quite lovely. The clip bar extends beyond the brooch, measures 2" long. The brooch itself is 1-1/4" diameter.  There are 11 blue crystal rhinestones set in a gold tone bezel casement with a "scarf" wrapping through the brooch painted with blue and yellow enamel.
