The difference between a crown and a tiara is that a tiara can be worn by any royal woman, whereas a crown is only used by a monarch (unless you’re a 5-year-old playing dress-up). Per Marie Claire Australia, there are specific rules for wearing the sparkling headgear. It’s reserved only for royal women over 18, and then only after they’re married. The monarch gifts tiaras from the palace collection, after which the royal keeps it all her life. Tiaras are considered evening wear except for weddings, where tiaras are always appropriate. For the wedding banquet of Jordan’s Prince Hussein and Princess Rajwa, Kate wore the stunning — and very recognizable — Lover’s Knot Tiara.
The diamond-and-pearl-festooned Lover’s Knot was famously given as a wedding gift to Princess Diana by Queen Elizabeth II. Sadly, the headpiece reverted back to the queen’s collection after Diana’s death, where it remained until it was passed on to Kate. The princess often wears it to special occasions, perhaps as a tribute to her beloved mother-in-law. But as the Mirror reports, up till now, Kate hasn’t worn a tiara since December 2022. Princess Beatrice, her cousin by marriage, arrived at the wedding wearing the same tiara her mother, Duchess Sarah Ferguson, wore when she wed Prince Andrew. Seeing the princesses not only in tiaras, but also ones with such positive memories, is a reminder of happier times within the palace.
