2025 $20 Fine Silver Coin Williamson Diamond Brooch

The Coin Company is proud to present 2025 $20 Fine Silver Coin Williamson Diamond Brooch by the Royal Canadian Mint.    

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.  

KEY FEATURES

• A pink-coloured glass stone stands in for the royal brooch’s pink diamond on the coin’s reverse, where the stone is surrounded by 28 crystals.
• Features a matte proof finish (brilliant relief, satin field) that allows the brooch to shine right on your coin’s reverse.
• Only 6,000 coins available worldwide. Also available: a 99.99% pure gold version, with diamonds and a pink tourmaline stone

2025 $20 Fine Silver Coin Williamson Diamond Brooch has a limited mintage of 6,000 coins.
