I'm trying to pin down more information on this amazing piece of jewelry. We all know that the necklace entered into the Windsor vaults through Queen Alexandra upon her marriage to Edward VII. What I'm trying to find out is whether or not we have any photographic or written confirmation that either Queen Mary or the Queen Mother wore the necklace. I'm always humbled and impressed by the knowledge here on the board, so I'm hoping someone will have some information. Thank you all in advance for your help.
