7 gorgeous royal family heirlooms that Kate Middleton wears regularly

Jewelry designer Nigel Milne created the three-strand pearl bracelet in 1988. Princess Diana wore it with her iconic "Elvis" dress and at the Birthright Ball, both in 1989.

Milne said he was "delighted" to see the Duchess of Cambridge making it her own.

"The Princess of Wales was the most wonderful inspiration for us jewelers in that she wore her jewelry with such style and panache," he wrote on his website.

This pearl Cambridge Lover's Knot tiara was given to Princess Diana as a wedding present from the Queen. The crown consists of 19 arches and contains 38 drop-shaped pearls suspended from pretzel-like twists known as lover's knot bows, according to People. While the Duchess of Cambridge doesn't wear tiaras all that often, she donned the crown at a diplomatic reception at Buckingham Palace in 2016.

Middleton has worn them several times, including on a 2016 royal tour to Holland. Queen Elizabeth last wore them for her Diamond Jubilee celebrations in 2012, acccording to People.

Middleton's red dress also paid homage to what Princess Diana wore after having Prince Harry.

Twitter user @hrhkatemeghan spotted Princess Diana's diamond and South Sea pearl dangle earrings worn by Kate Middleton at the 2019 BAFTAs. It was the first time that Middleton had worn these earrings. Princess Diana had worn the earrings to a gala at Bridgewater House in 1995.

At Archie's christening, Middleton wore the same pair of diamond and pearl drop earrings that Princess Diana wore to Harry's christening in 1984.

The sapphires in these earrings are believed to have come from the strap of a watch given to Princess Diana as a wedding present from the Crown Prince of Saudi Arabia, according to the Daily Mail. The Princess wore them as studs, and Middleton reinvented them with a drop-down style.

Princess Diana's engagement ring is one of the most recognizable rings in the world. A 12-carat sapphire surrounded by 14 diamonds, it was just another piece in Garrard's catalogue that any member of the public could buy until Lady Diana Spencer picked it as her engagement ring and made it famous, according to InStyle. Prince William proposed to Middleton with it in 2010 and she's continued to wear it since then.
