Meghan Markle won't be wearing this tiara when she marries Prince Harry

By: Sophie Hamilton

Diamond tiaras are a royal's best friend – especially on their wedding day! As Meghan Markle gears up to walk down the aisle and marry Prince Harry on May 19, royal watchers are wondering what gown and jewels she'll wear. Naturally, her choice of tiara is a hot topic: will Meghan choose a piece from the Queen's personal collection, a new design or will she bid adieu to tradition and not wear a tiara at all? One thing is certain, however: the Cartier Halo tiara which Duchess Kate wore for her wedding to Prince William is definitely ruled out.

Town & Country reports that the stunning Cartier Halo tiara is not even in the UK on Meghan and Harry's wedding date. The famous piece of jewellery will be on show at Cartier: The Exhibition at the National Gallery of Australia from March 30 to July 22. So there's no way Meghan could wear the iconic tiara. The site reveals that the piece is on loan to the gallery by the Queen and the Royal Collection Trust. The gallery confirmed the news to the publication.

We are all familiar with the Cartier Halo tiara from the Duchess of Cambridge's wedding day on April 29, 2011; she looked radiant in the piece, which was loaned to her for the day by the Queen. The beautiful tiara is named due to its halo shape and features over 800 diamonds. King George VI first commissioned Cartier to design the tiara for his wife, the Queen Mother in 1936, and it was then passed on to Queen Elizabeth on her 18th birthday. The piece has since been worn by other members of the royal family, including Princess Margaret, Princess Anne and of course, Kate.

All eyes will now be on Meghan to see which tiara she decides on, if at all. The Queen's tiara collection features some truly spectacular items, including the Lotus Flower tiara which once belonged to the Queen Mother. There is also the dazzling Cambridge Lover's Knot Tiara, which was the Queen's gift to Prince Harry's mother, Diana, Princess of Wales on her wedding day. Should Meghan opt to wear the Lover's Knot tiara it would be particularly poignant.
