The 11 Most Stunning Brooches in the Royal Vaults

The 23.6 carat centre-piece is considered the best pink diamond ever found, and was a wedding gift to the Queen from mine-owner Dr John Williamson. The jonquil-shaped brooch was designed by Cartier, and is comprised of dozens of brilliant, marquise and baguette-cut diamonds. Her Majesty has worn it many times, most significantly to the weddings of her sons Prince Charles and Prince Edward.
