There once was a member on here by the name of GillW who kept a data base on the Queens brooches. I tried to keep count of them once and got to 145 before giving up. I believe there are over two hundred now, depending if you count the pairs as one or as two. As Her Majesty will sometimes wear only one of a pair such as the Greville ruby and diamond brooches often worn by the Queen Mother. And then there are the Queen Victoria bow brooches of which there are three and one was lent to the Duchess of York.
Now do you count Queen Mary's stomacher as a stomacher and a brooch as the bottom half can be worn as a brooch. The ears of wheat hair clips can also be worn as brooches.
Do you remember when President Obama gifted HM with a Moss Agate brooch. An interesting piece.
