Offering for sale a wonderful old brooch clip by Boucher, and so signed on the back. It is made of a gold metal of unknown content, with blue stones of varying shades. Boucher was famous for making the costume with the same techniques and care as one would find in "real" jewelry. It is in very good condition, with no missing stones or damage. It measures 1 & 5/8" across at the widest point. I bought this over 20 years ago from a fine costume jewelry dealer that traveled the country.
