Princess Eugenie may follow in the footsteps of her mother and wear the York diamond tiara on her wedding day.
The delicate scroll tiara is set in platinum with leafy scrollwork, diamond collets and a large diamond of around five carats on the top.
But it later emerged that the new piece had been purchased for the duchess from jewellers Garrad by the Queen and the Duke of Edinburgh as a wedding gift.
She wore the sparkling piece many times after and retained ownership of it following her split from Andrew in 1992.
Eugenie could choose to wear pieces from this collection on her big day.
The Queen often loans royal brides pieces from her personal collection.
Here are some of the other options for Eugenie:
Grand Duchess Vladimir’s Tiara
This imposing tiara features 15 interlaced diamond circles with large pearl droplets.
The pearls can be taken out and replaced with emeralds or it can be worn “widowed” – without drops.
It was found by a member of the British Secret Intelligence Service who smuggled the jewels out of Russia for the Grand Duchess.
It was later sold to Elizabeth II’s grandmother, Queen Mary, and was then eventually inherited by the Queen. It has also been worn by the Duchess of Cornwall.
The Oriental Circlet Tiara (also known as the Indian Tiara)
This was a favourite of the Queen Mother. The large but delicate-looking piece features diamond lotus flowers and arches, and wraps itself nearly all the way around the wearer’s head.
But Queen Alexandra later replaced the opals, which were thought unlucky, with rubies.
Queen Mary’s Fringe Tiara
The Queen wore Queen Mary’s Fringe Tiara when she married the Duke of Edinburgh in 1947.
Strathmore Rose Tiara
A demure choice would be the pretty Strathmore Rose Tiara, which belonged to the Queen Mother and was a present from her parents in 1923.
Queen Alexandra’s Russian Kokoshnik Tiara
If Eugenie wanted to go all out and pick one of the largest tiaras, she could opt for this impressive fringe headdress.
Queen Mary’s Girls of Great Britain and Ireland Tiara
This is an unlikely choice. One of the Queen’s favourites, the tiara is synonymous with the monarch and she wears it often.
