Product Details
One of Queen Elizabeth II’s most iconic brooches, the flower-shaped Williamson Diamond Brooch features a gorgeous pink diamond, one of the largest and finest of its kind, and was a wedding gift from Canadian geologist John Thoburn Williamson.

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 colored glass stone stands in for the royal jewel’s priceless pink diamond.


Coin Highlights:
  • Contains 1 oz of .9999 fine silver, adorned with crystals and a colored glass stone on a rhodium plated setting.
  • A pink-colored glass stone stands in for the royal brooch’s pink diamond on your coin’s reverse, where the stone is surrounded by crystals.
  • Your coin is encapsulated and presented in a Royal Canadian Mint-branded clamshell with a black beauty box.
  • Limited mintage of 6,000 coins.
  • Obverse: The obverse features the effigy of His Majesty King Charles III by Canadian artist Steven Rosati.
  • Reverse: The coin’s reverse features an interpretation of the Williamson Diamond Brooch frequently worn by Queen Elizabeth II throughout her seven-decade reign. Flanked by engraved floral accents inspired by the brooch’s shape, the jewel’s five-petaled flower is a rhodium-plated setting adorned with crystals and a pink-colored glass stone at its center.
  • Guaranteed by the Royal Canadian Mint.
