2025 $200 Williamson Diamond Brooch - Pure Gold 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:

Re-creating the look of the original brooch, the engraved five-petalled flower is adorned with a pink tourmaline gemstone and 28 round-cut diamonds, all set in a silver mount plated with platinum, which extends its luxurious shine to the floral elements on the reverse and the effigy on the obverse.
