 | The Williamson pink diamond brooch was often worn by Her Majesty and was one of her favorites. It includes one of the rarest flawless pink diamonds in the world. The Queen received the 54.5-carat rough pink diamond in 1947 as a wedding gift from Canadian geologist Dr. John Thorburn Williamson. The cut gem is 23.6 carats. Thought to be the second most valuable in the Queen’s collection, the Williamson brooch is estimated to be worth at least $40 million. |
