Royal women are not permitted to wear tiaras until they are married, hence why blood-born royals like Zara Tindall are not seen wearing a diadem until their wedding day. The same rule applies to women who marry into the Royal Family, such as Kate Middleton or Meghan Markle.
Zara rocked a very unusual choice for her wedding tiara, as royal fans were expecting her to wear something else.
It is a tradition in the Royal Family that Princesses will wear the same wedding tiara that their mother wore.
For instance, when Princess Anne walked down the aisle to marry Captain Mark Phillips in 1973, she wore Queen Mary’s Fringe tiara, the same diadem worn by Queen Elizabeth II in 1947.
As Zara is The Princess Royal’s daughter, many assumed she would also wear Queen Mary’s Fringe tiara.

However, this was not the case, and many fans had never heard of the tiara that Zara wore because it belonged to her great-grandmother.
But, as a jewellery expert points out, this tiara did give a special nod to Princess Anne.
Deborah Papas from Prestige Pawnbrokers of Channel 4’s Posh Pawn, spoke to Express.co.uk to provide expert commentary on Zara’s wedding tiara.
She said: “This is the most glamorous piece from Princess Anne’s stunning jewellery collection.
DON’T MISS:
“It has a centre laurel and honeysuckle decoration on either side.
“It is studded with diamonds set in a white precious metal more likely to be platinum because of the era in which it was made. It is perceived to be made by Cartier in France.”
The jewellery expert gave a rough estimate of how much Zara’s wedding tiara is worth.
Deborah claimed: “It is not known how much the tiara is worth, but Papas estimates it to be worth over £1million. If it is a Cartier piece, it could be as much as £2million to £4million.”
