Fit for a queen: A pink tourmaline and diamonds add majesty to this brooch tribute.
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 intricate shape of the Williamson Diamond Brooch is on full display for all to admire on this 99.99% pure gold coin, the second in our Crown Jewels series. On your coin’s reverse, the brooch’s five-petalled flower is adorned with a pink tourmaline gemstone and 28 round-cut diamonds, all set in a platinum plated mount, which extends its luxurious shine to the floral elements on the reverse and the effigy on the obverse.
CARACTÉRISTIQUES DE LA PIÈCE
Second Crown Jewels coin. Launched in 2024, the Crown Jewels series takes a closer look at some of the Royal Family’s most magnificent heirloom brooches.
A royal brooch with a Canadian connection. This 99.99% pure gold coin features an interpretation of the Williamson Diamond Brooch. The jewel was designed around a stunning pink diamond that was presented to then-Princess Elizabeth as a wedding gift from Canadian geologist John T. Williamson.
Pretty pink tourmaline. Graded AAA quality, a 0.50-carat round-cut Fancy Pink tourmaline gemstone stands in for the brooch’s central stone on your coin’s reverse, where it is set in a sterling silver-and-platinum-plated mount.
Incomparable diamond sparkle. Also set in the platinum-plated mount are 28 round-cut diamonds (0.41 carat total weight) that bring some of the original brooch’s sparkle to this collectible tribute.
Beauty and rarity. Previous crown- and tiara-themed coins sold out quickly, and only 225 coins are available to collectors worldwide.

À PROPOS DE LA MONNAIE ROYALE CANADIENNE
La Monnaie royale canadienne est connue pour être l'une des monnaies les plus réputées au monde. La succursale d'Ottawa de la Monnaie royale a ouvert ses portes en 1908 et a été rebaptisée Monnaie royale canadienne en 1931 lorsque le contrôle a été transféré au gouvernement canadien. Ses normes élevées d'excellence et de qualité lui ont permis d'être la première raffinerie à fabriquer des pièces d'investissement en or d'une pureté de 9999 en 1982, ainsi que la première à atteindre une pureté d'or de 99999 en 1998.
