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.

Sold out at the mint! 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.

Coin Highlights:
  • Contains 1.93 oz of .9999 fine gold with a platinum-plated silver mount and 28 round-cut diamonds (.41 carat total weight) and a pink tourmaline.
  • Your encapsulated coin comes packaged in a premium wooden case with a black beauty box.
  • Mintage of only 225 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. Re-creating the look of the original brooch, an engraved five-petaled jonquil flower is adorned with a silver-and-platinum-plated mount consisting of a 0.50-carat round-cut pink tourmaline gemstone and 28 round-cut diamonds (0.41 carat total weight). The stylized floral accents engraved on both sides of the sparkling centerpiece are also inspired by the royal brooch and are plated with platinum.
