Prince Harry is reportedly set to turn Princess Diana's tiara into an engagement ring for his girlfriend Meghan Markle.
The 32-year-old royal has been dating the American actress since last year, and it is believed he is now looking at transforming his late mother's emerald tiara into a sentimental engagement ring so he can pop the question to the brunette beauty later this year.
A source said: "Diana's jewellery collection was left in trust for the boys and Meghan apparently loves emeralds. For Harry, like Wills before him, using his mother's gems means the two loves of his life will forever be linked."
Harry is reportedly working on "something incredible" with jewellers, so that he can give Meghan, 35, "the same sentiment" that his brother Prince William had when he proposed to his now-wife Catherine, Duchess of Cambridge, using Princess Diana's engagement ring.
The source added to the Daily Star newspaper: "After Diana died, the boys both chose a keepsake from Kensington Palace when they moved to Charles' rooms in St James's Palace. Prince William picked his mum's Cartier watch, and Harry picked her sapphire and diamond engagement ring.
"But they had an agreement that whoever got engaged first would have Diana's ring - and of course that was William and Kate. Harry wants the same sentiment when he proposes to Meghan, so he is working with the jewellers to design something incredible."
Meanwhile, a source previously claimed that Harry would propose to the 'Suits' actress in the summer, as the pair have openly discussed taking their relationship to the next step.
They claimed: "They will be engaged by the end of summer. [They] have spoken candidly about their future. They see a life together."
