Yours to own: A pink-hued tribute to an iconic royal brooch.
One of Queen Elizabeth II’s most iconic brooches, the flower-shaped Williamson Diamond Brooch has a Canadian connection: its gorgeous pink diamond, one of the largest and finest of its kind, was a wedding gift from Canadian geologist John Thoburn Williamson. The extraordinary jewel was cut and set into a platinum-and-diamond brooch completed in 1953, the year of Queen Elizabeth II’s coronation, and was frequently worn throughout her seven-decade reign, appearing in family portraits, at State occasions and momentous celebrations — including the Silver Jubilee Service in 1977, and the weddings of two of her children.
The second coin in the Crown Jewels series takes a closer look at the Williamson Diamond Brooch. The brooch’s jonquil flower on this 99.99% pure silver coin is adorned with dazzling crystals on a rhodium plated setting, while a coloured glass stone stands in for the royal jewel’s priceless pink diamond.
COIN HIGHLIGHTS
- Second Crown Jewels coin. Launched in 2024, the Crown Jewels series takes a closer look at some of the Royal Family’s most magnificent heirloom brooches.
- A royal brooch with a Canadian connection. This 99.99% pure silver coin features an interpretation of the Williamson Diamond Brooch. The jewel was designed around a stunning pink diamond that was presented to then-Princess Elizabeth as a wedding gift from Canadian geologist John T. Williamson.
- Matte proof finish. A matte proof finish (brilliant relief, satin field) allows the brooch to shine bright on your coin’s reverse.
- A must-have for jewellery lovers. Mintage is limited to 6,000 coins and this one will likely sell out quickly.
- Includes serialized certificate. The Royal Canadian Mint certifies all of its collector coins.

Your coin is encapsulated and presented in a black Royal Canadian Mint-branded clamshell with a black beauty box.
COLOURED STONE
A pink-coloured glass stone stands in for the royal brooch’s pink diamond on your coin’s reverse, where the stone is surrounded by crystals.
RHODIUM PLATED SETTING
