“Sadly, the final time Diana wore the earrings was on the day the Prince of Wales confessed to adultery.

“The Duchess of Cambridge now showcases the earrings and often pairs them with the famous Queen Mary’s Lover’s Knot Tiara – which exposes suspended pearls from the tiara, creating a marvellous display of pearls and diamonds, just like Diana once did.”

Queen Mary was known to be a huge jewellery lover, introducing several other tiaras into the royal collection too.

Queen Mary’s Fringe Tiara has been worn by three generations of Windsor women for their royal weddings.
