In 2017, the term sapphire jubilee or blue sapphire jubilee was coined for the celebrations to mark the 65th anniversary of the reign of Queen Elizabeth II (see Sapphire Jubilee of Elizabeth II). Previously, the sapphire wedding anniversary was understood to be the 45th, and this would be expected to carry over to regnal anniversaries as with silver, golden, and diamond jubilees.
