Sonia Rykiel Rhinestone Brooch Pin, Late 1970’s rare signed piece from Paris

Beautiful Sonia Rykiel sparkly deep blue pin/brooch to add retro Parisian elegance to your dress, blouse, or coat. Missing 1 to 2 tiny blue stones, but hardly noticeable unless you look closely. Comes in original pouch. Dimensions are 3” long, 1 5/8” wide. 8 large white baguette rhinestones, over 180 small royal blue round rhinestones. This brooch/pin weighs 1 1/2 ounces. Every stone is slightly different in size. Originally purchased in the late 1970’s in Paris for more money then the price being offered here. So with inflation, I should be charging probably $800 for this. Especially since it’s so vintage, early Sonia Rykiel. Signature is molded only “SONIA RYKIEL,” not Sonia Rykiel
Paris, like her later pieces. This is very collectible early career Sonia Rykiel. I’m surprised an antique or fashion specialty jeweler hasn’t spotted and purchased this amazing early Sonia Rykiel costume piece already for their own store to resell. But you, a retail customer, could get it before they do.
