Royal fans have speculated that the relative of the Queen might wear a tiara that has not been seen for many years, and the same one that her grandmother wore.
Gabriella could wear the Kent City of London Fringe.
Given as a gift to her grandmother Princess Marina of Greece and Denmark, the gift would not be allowed today due to rules surrounding royal gifts.
However, it has also been suggested that she might wear the Kent Pearl Festoon Tiara, which her mother wore in the past.
It is a diamond tiara with pearls along the top and around the base.
Or could Gabriella take her cue from her mother and not wear a tiara for her wedding at all?
Princess Michael did not wear a tiara for her ceremony – but she did wear the Kent City of London Fringe tiara for her reception.
Meghan Markle’s wedding tiara was the Queen Mary’s Lozenge Bandeau tiara.
The huge diamond brooch in the centre of the tiara brings the eye catching glimmer to this piece.
It hasn’t been seen since it was last worn by Princess Margaret in 1965.
Kensington Palace confirmed the tiara is the Queen Mary’s Lozenge Bandeau tiara, and tweeted: “The veil is held in place by Queen Mary’s diamond bandeau tiara, lent to Ms. Markle by The Queen.
“The diamond bandeau is English and was made in 1932, with the brooch dating from 1893.”
Princess Eugenie’s wedding tiara was the Greville Emerald tiara.
The piece is Margaret Greville’s Kokoshnik Emerald Tiara. It was made by made by Boucheron in 1921 and the whopping centre emerald is 93.70 carats.
