A decoy was used when it was sent to England. The real one was sent by mail in a plain box.
Discovered in 1905 at the Premier Mine in South Africa, the Cullinan Diamond remains the largest gem-quality diamond ever found.
To ensure its safe delivery to the United Kingdom, an unusualāand ingeniousāplan was devised. The diamond was sent in an unmarked package by registered mail, while a decoy stone was transported aboard a Royal Navy steamboat with great fanfare to mislead potential thieves.
The real Cullinan Diamond quietly made its way to Buckingham Palace, where it was inspected by King Edward VII.
Named after Sir Thomas Cullinan, founder of the Premier Mine, the massive diamond was eventually cut into several stones.
The largest two became part of the British Crown Jewels, cementing the Cullinanās place in history.
