A diamond tiara worn by Meghan Markle at her wedding to Prince Harry could feature in the King's coronation this weekend.

The Bandeau Tiara, made for Queen Mary in 1932, features 11 sections of interlaced ovals and pavé diamonds and was designed to hold a brooch given to the late Queen in 1893.

The head piece was given to Queen Elizabeth II and later loaned to the Duchess of Sussex for her wedding to Prince Harry.

However, the loan was not without controversy as the Bandeau Tiara was not Meghan’s first choice.

She had hoped to wear the Queen’s Greville Emerald Kokoshnik tiara on her wedding day but the request was denied.

As a prized piece of royal jewellery, the Bandeau Tiara is rumoured to have a prominent place in this weekend’s coronation.

A spokesman from jewellery expert Glamira said: “The jewellery worn by the royals is particularly interesting due to its high value, rich history and overall extravagance.

Whether that be regularly worn pieces such as Kate’s engagement ring or an item we are yet to see like the coronation necklace, it’s certainly something that many are looking forward to witnessing at the ceremony.”

The coronation necklace dates back to 1858 when it was made and presented to Queen Victoria. It was worn by several queens during their coronations including the late Queen Elizabeth II in 1953.

Other pieces of jewellery that could make an appearance include the Granny Chips brooch, considered to be the most expensive brooch in the world, the Greville Festoon necklace, worth around £8 million, and the Swan Lake necklace, worn by Princess Diana at a performance of Swan Lake at Royal Albert Hall in London, her last official event.

It comes as searches for the term “coronation jewellery” increase by 833 per cent in the past year, according to Glamira.
