One of most notable costume jewelry companies on production of shoe clips was Bluette, which manufactured shoe clips in the 1970-80s. The history of Bluette costume jewelry trademark began fifty years ago in France. Incorporated in January 1972, Monsieur Robert Bluette company ceased to exist in 2002.
This lovely pair of shoe clips was barely used.  The silver-tone with rhinestone design has stones that dangle at bottom.
