Queen Elizabeth celebrated her diamond jubilee on June 5th. Her Majesty wore a diamond brooch jokingly referred to in the royal family as “Granny’s Chips”. Granny was the Queen’s grand-mother, Queen Mary.
The two diamonds making up this pin are the Cullinan III and Cullinan IV, two of several stones cut from the Cullinan Diamond in 1905. The Cullinan diamond was found in South Africa and presented to Edward VII on his birthday. The two stones cut from the diamond and used for ”Granny’s Chips” are a clear pear shaped stone of 94.4-carat and a 63.6-carat cushion shaped stone. Queen Mary had these stones made into a brooch with the Cullinan III hanging from the IV. Queen Elizabeth II inherited the piece from her grandmother in 1953. The brooch is the most valuable brooch in the world with a value of over £50,000,000
However, please be amazed to know that ”Granny’s Chips” are worn here by Queen Mary under the bottom row of diamond rivieres she is wearing. Queen Mary ordered the Cullinan I 530.20 carat pear-shaped diamond and Cullinan II 317.40-carat cushion-shaped diamond to be temporarily removed from the Crown Jewels, so she could wear them mounted as a brooch as seen here on her devant -corsage to the opening of Parliament in 1910. No other Queen consort has ever looked more Imperial.
