2025 $20 Williamson Diamond Brooch - Pure Silver Coin

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 Design:

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. Second coin in the Crown Jewels series, the invaluable Williamson Diamond Brooch.
