Kate Middleton’s most valuable jewellery, from Princess Diana’s engagement ring to Queen Elizabeth’s US$1 million Lover’s Knot tiara and Royal Family Order brooch

- The queen loaned the Duchess of Cambridge some of her most prestigious pieces, including the tiara Garrard made for Queen Mary
- Prince Harry gave his mum’s ring to Prince William for his proposal to Kate, while she wore her own blinging Cartier necklace for the 2012 London Olympic Games
Here we take a look at some of the most jaw-dropping jewellery she has rocked since becoming a royal.
Queen Mary’s tiara and brooch set: at least US$1 million
Queen Elizabeth loaned Kate Middleton the Lover’s Knot tiara, plus a necklace and earrings, to wear to a state dinner at Buckingham Palace in October 2018. The items were created by Garrard for Queen Mary in 1913 or 1914. The tiara alone is thought to be worth at least US$1 million today.
As if that wasn’t enough, the queen also loaned her Royal Family Order brooch that features a painting of her – said to be the greatest honour a member of the family could receive.
“I can confirm that Her Majesty awarded the Duchess of Cambridge with the Order in 2017,” a spokesperson told Vanity Fair at the time – six years after Kate officially became a member of the royal family.
