While many celebrity possessions end up at auction houses and museums, the royal family made sure to safeguard Diana's valuables after her death.
Since tying the knot with William, the Duchess of Cambridge has been incorporating some of the late Princess's most prized items into her style as a way to honor her memory.
The pregnant royal showed up for a black tie event at the Residence of the British Ambassador in Stockholm, Sweden in a bold floor length dress accessorized with Diana's Collingwood pearl earrings and bracelet.
Kate seems to be fond of the pearl set because she has previously worn them on a number of occasions, including during a visit to Germany last year.
Diana first wore the beloved earrings at a banquet a month before her wedding. Since then, she was spotted wearing them on multiple occasions, including her wedding day.
She was last pictured with the earrings on the night the Prince of Wales confirmed his affair with Camilla. She paired them with the iconic black "revenge dress" and sapphire choker.
In addition to jewelry, Kate has also previously worn Diana's favorite tiara, The Queen Mary's Lover's Knot, a handful of times.
Although she always has the choice to opt for new accessories, Kate is often spotted wearing Diana's because it's a way for her to pay homage to the mother-in-law she never had the honor of meeting.
