Shimmering vintage floral basket brooch by Trifari

Aurora borealis stones light up this lovely piece, which measures 1-5/8 X 1-1/2 inches. I've seen the same design with faux pearls in place of the rhinestones. The maker's mark with the crown above the letter T dates this piece between 1937 and 1955. In great condition. (One of the stones had fallen off, but I had it and put it back.)
