Television's reality star Kim Kardashian has acquired a piece of royal history - a pendant once worn by Princess Diana. She bought the Attallah Cross pendant at the Sotheby's Royal and Noble Sale on Wednesday. Her representative bid $197,453 for the necklace, outdoing three other bidders.

According to Sotheby's the pendant sold for more than double its pre-auction price.

Here's what you need to know about the pendant:

1. The pendant formerly belonged to the Collection of the late Naim Attallah, CBE Garrard
2. The Fleurée cross set with square-cut amethyst and accented by circular-cut diamonds.
3. During the late 80s Diana, Princess of Wales, became known for bolder fashion choices reflecting how she had begun to take autonomy in her life.
4. In 1987 that Garrard lent her this distinct and eye catching early 20^th century amethyst and diamond cross to pair with an exquisite baroque style purple and black velvet Catherine Walker & Co dress.
5.Over the years, she would go on to collaborate with Garrard, borrowing her favourite amethyst and diamond cross on many more occasions, as recalled by Ramsay Attallah, whose father, Naim Attallah, CBE (1931-2021) was joint managing director and eventually group chief executive of Asprey & Garrard.
