Kim Kardashian went on Instagram and bragged about an expensive purchase, as she acquired the gold cross of the late Princess Diana.

However, the respective comments have compared her to Lord Voldemort, the main antagonist in the Harry Potter novel and movie series, because of her collection of dead people's belongings.

The aforesaid jewelry was sold by Sotheby's auction house.

The amethyst pendant was made in the 1920s by the Garrard jewelry company.

It went under the hammer at twice its original estimate.

Before this purchase, Kim Kardashian had bought Lorraine Schwartz jade bracelets that were previously worn by actress Elizabeth Taylor, and Cartier watches that belonged to former US First Lady Jacqueline Kennedy.

The late Princess of Wales wore this piece of jewelry many times, but most notably—at the 1987 Birthright charity gala in London.
