Rhodium plated molded blue resin flowers with leaves brooch with security clasp. It is unmarked but has the plaque where the mark should be. It also came with the matching earrings which are signed. I had the pink version in the past and included a picture of the back for reference. Measures: 32 1/8 inches long by 2 inches wide. Condition: Very good; one of the metal loops has thin section from manufacturing.  A brooch like this in pink was featured in a 1955 advertisement that ran in Vogue magazine. The matching clip earrings are also available for purchase.
