Historical overview

The Williamson Diamond brooch, which served as the inspiration for the 2025 coin in the Crown Jewels series, has a rich and unique history tied to the British royal family. The centerpiece of this brooch is an extremely rare pink diamond, which was discovered in 1947 at the Mwadui mine in Tanganyika (now Tanzania) by Canadian geologist John Thorburn Williamson, the mine’s owner.

That same year, Williamson presented a 54.5-carat rough diamond to the young Princess Elizabeth as a wedding gift to mark her marriage to Prince Philip. This gesture was an expression of his appreciation and loyalty to the monarchy, as well as a tribute to the future queen. The diamond was later cut into a dazzling round stone weighing 23.6 carats. Its extraordinary, naturally pink color makes it one of the rarest and most valuable gems in the world.

In 1952, Cartier set the diamond into a spectacular flower-shaped brooch—featuring a central pink stone surrounded by petals formed from over 200 smaller, colorless diamonds. The brooch quickly became one of Queen Elizabeth II’s favorite pieces of jewelry, and she wore it on numerous occasions during important ceremonies and diplomatic events. It symbolized not only a personal gift from her engagement, but also the strong ties binding the monarchy to Canada and the Commonwealth.

Manufacturer

As Canada's independence from Great Britain grew, so did the need to mint its own coins. Therefore, in 1908, the Royal Canadian Mint was established and has since become one of the most important mints in the world. To date, all coins from the Royal Canadian Mint bear the portrait of the reigning British monarch. 

The shares of the Mint are held in trust for the Crown of Canada. 

The Mint produces all Canadian circulation coins and designs and manufactures collector coins made of precious metals—gold, silver, palladium, and platinum bullion coins, medals, medallions, and tokens. It also offers gold and silver refining services. 

Today, the Royal Canadian Mint sets the standard in minting technology and numismatic design, reflecting its position and reputation.
