The Cullinan III and IV Brooch
Discovered 18 feet below the surface at the Premier Mine in 1905, the largest diamond ever to be found weighed at 3105.75 carats. The diamond was sent to crafters and after eight long months, it was split and cut into nine stones of high-quality. The Cullinan I or known as the Great Star of Africa, and the Cullinan II or known as the Lesser State of Africa are both part of the British Crown jewels. The Cullinan III and IV, also known as the lesser stars of Africa were made into a brooch for Queen Elizabeth in 1910.
