Only Queen Elizabeth could christen the diamonds in this brooch Granny’s Chips. They are so named because they were originally set in Queen Mary’s crown for the Coronation of George V in 1911. The top stone, known formally as the Cullinan IV, is 63.6 carats, and the bottom stone, the Cullinan III, is 94.4 carats.  Here are photos of the brooch itself, and being worn by Queen Elizabeth. Don’t you love how disinterested the corgi is? Clearly not a jewel lover.
