Kate Middleton looked stunning as usual during her first-ever solo trip. The Duchess of Cambridge was in the Netherlands Tuesday for a one day tour. The special occasion was the first time Middleton embarked on a royal engagement without her husband, Prince William.

Middleton has been known for wearing dazzling dresses and breathtaking jewels on her royal outings, and her trip to the Netherlands was no different. Vanity Fair reported that the mother of two greeted King Willem-Alexander at his residence Villa Eikenhorst in a pale blue skirt suit designed by Catherine Walker. She paired the look with nude pumps, and a pair of pearl and diamond earrings.

The Daily Mail’s royal correspondent Victor Murphy tweeted that Middleton’s earrings actually belong to her grandmother-in-law, Queen Elizabeth.

This isn’t the first time Prince George’s mom has borrowed from Her Majesty’s prized jewelry collection. People magazine reported last week that the Duchess of Cambridge sported two vintage bracelets from the Queen’s collection for a state banquet dinner at Buckingham Palace.

The outlet wore that on Middleton’s left wrist was Queen Elizabeth’s diamond and platinum wedding bracelet, designed by Prince Philip for their 1947 nuptials. On her right wrist, Middleton wore a diamond bracelet known as the Queen Mary Chain-Link Bracelet. The pricey piece is said to have been a favorite of Queen Elizabeth’s mother, the Queen Mother. Sources told People that the bracelet was made in 1932.

Middleton has also been seen several times rocking a stunning pearl and diamond tiara fit for royalty. She wore the tiara last week to the state banquet, and also on her wedding day in 2011. The tiara, known as the Lotus Flower, belongs to Queen Elizabeth and dates back to the late 1920s.

During the royal family’s week-long tour of Canada this month, Middleton was photographed a few times wearing another one of the Queen’s prized possessions: a diamond and platinum Maple Leaf brooch.
