A Royal Wedding 20 November 1947

The Williamson Diamond brooch

Cartier, London


The central diamond of 23.6 carats is the finest pink diamond in existence. It was excavated from a mine in Tanganyika (Tanzania) belonging to the Canadian geologist Dr John Williamson, who gave it as a wedding present to Princess Elizabeth in 1947. It was cut by Briefel and Lemer of London in 1948 and set in the centre of a new brooch designed by Frederick Mew of Cartier in 1952.
