Kim Kardashian has added a royal item to her jewelry collection.

The "Kardashians" star is the new owner of Princess Diana's iconic Attallah cross, Us Weekly reported.

TMZ was the first to break the news that Kardashian paid $200,000 for the pendant previously loaned to the late Princess of Wales.

Kardashian, 42, purchased the pendant via Sotheby's auction Royal and Noble sale, which opened earlier this month. The dazzling piece was valued at around $98,668 to $148,002.

The piece features a Fleurée cross set with square-cut amethysts and circular-cut diamonds. It was created in the 1920s by court jeweler Garrard. Naim Attallah purchased the item and lent it to Prince William and Prince Harry's mom in 1987.

Princess Diana wore the sparkler to an event for Birthright, a charity that protects human rights during pregnancy and childbirth. The fashion icon paired the amethyst and diamond cross with an eye-catching black and purple Catherine Walker & Co. gown.

The piece was reportedly one of the late royal's favorites, according to Sotheby's.

"Through Attallah's friendship with Princess Diana, he loaned it to her several times over a number of years," Sotheby's wrote via Instagram Saturday of Diana, who died at age 36 in a car crash in Paris in 1997. "It is understood that the cross was only ever worn by the Princess, and following her death, it was never seen in public again until now."

The luxury marketplace added, "The pendant is a highlight of the Royal & Noble sale, which is open for bidding online until [Jan. 18]. The exhibition is open to the public at our New Bond Street galleries in London until [Jan. 18]."

This wasn't the first time the Skims founder has purchased a highly-coveted item.

Kardashian previously scored Jackie Kennedy's Cartier watch through Christie's for $379,500 in 2017, TMZ reported. The timepiece was a present from Kennedy's brother-in-law Prince Stanislaw "Stas" Radziwill.

Kardashian also bought Janet Jackson's iconic outfit from her 1993 music video for "If." She paid $25,000 for the custom-made top and pants to honor Jackson on her 55th birthday.

"Happy birthday, queen!" Kardashian wrote on her Instagram Story next to an original clip of Jackson sporting the outfit, Harper's Bazaar reported. "For @janetjackson's [birthday because] I'm such a fan. I can't believe I won this on juliens_auctions."

"Thank [you] so much @kimkardashian! I hope 'IF' gives [you] as much pleasure as it did me," the "That's The Way Love Goes" songstress responded to Kardashian's auction win.
