The first gift Princess Grace received from Princess Antoinette, the only sibling of Prince Rainier, III was this heirloom brooch. Over time, she received numerous pieces of family jewelry, but this one meant the most to her. Princess Grace often thought of it as a wedding gift from her new sister-in-law, Princess Antoinette. It was suggested that it be worn during formal dinners and since no chain was included with the original gift, Princess Grace had a one added by a famous French jeweler. This pendant is still in the family, and will continue to be past down through the generations. The rendering from Clairion-Pell is rhodium plated with sapphire blue and clear Swarovski crystals.
