The Duchess of Sussex is banned from borrowing any jewellery from the Royal Collection, sources claim.
The Queen allegedly approved a ban which forbids Meghan Markle from wearing any of the historic pieces such as diamond necklaces, brooches and tiaras.
The ban was also backed by Prince William, The Sun reports.
Among the priceless items is the Queen Mary Fringe Tiara for example, which can also be worn as a necklace, and was made for Queen Mary in 1919.
The collection also includes jewels worn by Meghan’s late mother-in-law Princess Diana, BirminghamLive reports.
Meanwhile, the Duchess of Cambridge has been pictured wearing pieces from the collection on multiple occasions, including the The Cambridge Lover’s Knot Tiara designed by Queen Mary, which became one of Diana’s signature tiaras.
Sources claim the Queen’s ban is not necessarily permanent and that Meghan could be allowed to borrow items in the future.
It is not the first time Meghan has reportedly missed out on royal jewellery.
Kate’s iconic engagement ring actually belonged to Harry following the death of Princess Diana in 1997, former royal butler Paul Burrell confirmed.
However, in a touching sacrifice, Harry offered his brother the chance to use it instead.
Paul said: “Harry said to him: ‘Wouldn’t it be fitting if she had mummy’s ring?’.”
“Then one day that ring will be sat on the throne of England. Harry gave up his precious treasure.
“His one thing he kept from his mother, he gave to his brother. That’s selfless, kind and exactly who Diana was.”
Burrell made the comments in an Amazon Prime documentary, it has been reported.
