Kim Kardashian has bought a bold cross necklace once favored by Princess Diana -- and which has not been seen in public since the late royal's death in 1997, according to Sotheby's, the global auction house that coordinated the significant purchase.
The Attallah Cross, an amethyst and diamond pendant, was made in the 1920s. In the 1980s, it was owned by Naim Attallah, a former group chief executive of the luxury jewelry company Asprey and Garrard. Sotheby's said its diamonds are about 5.25 carats, and overall, the statement piece measures approximately 5.3 inches by 3.7 inches.
Princess Diana notably wore the Attallah Cross on Oct. 27, 1987 at a charity gala held in support of Birthright, a charity supporting pregnancy and childbirth research. Now known as Wellbeing of Women, the charity has expanded its scope since the 1980s to encompass research focused on women's health.
