The modern list.
An updated modernised list, also known as the contemporary wedding anniversary list, has been produced in more recent times. This list has anniversary symbol gifts every year from the first anniversary through to the 50th, and then every fifth year thereon to the 100th anniversary.

Two Diamond anniversaries?
A Diamond anniversary actually appears twice for both the 60th and 75th This is due to Queen Victoria's Diamond jubilee on the 60th anniversary of her accession to the throne. Originally the Diamond anniversary was the 75th but since this event in 1897, Diamond has been the symbol of both.
