The listing, Givenchy blue and purple AB pin has ended.
Modern Givenchy pin. 2" wide x 1.5"high. Round and square blue ab crystals, three marquise deep purple ab crystals and six purple round ab crystals. Set in dark grey metal. Not plated. Picture does not properly display the sparkle of the crystals. I purchased at Lord and Taylor 15 years ago to wear with black and blue dress. It is signed Givenchy on back, but difficult to see without magnification.
