Princess Beatrice is likely to wear this tiara on her wedding day

Princess Beatrice is set to walk down the aisle next year, and has reportedly planned to shun most royal wedding traditions. However, one thing she probably won't compromise on is the wedding tiara, even though technically, like Princess Eugenie before her, she's not allowed to wear one.

That's because according to protocol, only married women are allowed to wear them, and they are reserved for the evenings only, but of course for such an important occasion, exceptions are made.

When Princess Eugenie got married last year, she surprised everyone by wearing the Greville tiara. The honeycomb diamond and emerald tiara was of a favourite's of the Queen Mother. It was created by famous French jewellers Boucheron, and belonged to heiress Margaret Greville, who left it to the Queen upon her death.

It was surprising that Eugenie chose it as it was thought she'd want to honour her mother Sarah Ferguson by wearing the same tiara she wore on her wedding day.

Whilst Fergie entered the church wearing a floral crown, she left it wearing a gorgeous tiara, which she had hidden underneath it.

Named the York tiara, the diamond headpiece has a centre stone of five carats surrounded by floral scrollwork, and it was specially commissioned by the Queen as a wedding present.

That in itself was unusual, as brides tend to borrow from the royal collection - both Meghan and Kate did it.

So it wouldn't be surprising if Princess Beatrice wore the York tiara on her own big day. Watch this space.
