Of all the recent royal brides, there is no doubt that Princess Beatrice has been the most unusual so far.

She wore a dress borrowed from the queen, a crown that the queen wore on her wedding day and broke the rules with her wedding ring.

What do we mean by "broke the rules"? According to tradition, royal couples should have a wedding ring made of Welsh gold, a custom which began in 1923 with the Queen Mother.

In fact, the wedding rings of the Queen Mother, Queen Elizabeth, Princess Margaret were all made of the same thing.

Since then, Prince Charles, Princess Anne, Princess Diana, Duchess Camila, Kate and William, Meghan and Harry and most recently, Princess Eugenie and Jack Brooksbank, all used Welsh gold for their wedding rings.

While Princess Beatrice had a wedding ring made by the same British jeweler who created her engagement ring, Shaun Leane, who also unveiled a photo of the design.

The ring is made of platinum and diamond and has a fusion of Victorian and Art Deco patterns. She has a curved shape that makes her fit perfectly with her engagement ring.

The ring had a personal and sentimental meaning for the newlywed couple and it must be said that it is unique.
