"[A] 2007 throwback. So this necklace that I have on is a diamond cross from Jacob and it was the first piece of jewelry that I bought when I got my first check,” she wrote. "When I was robbed, this was taken from me. However, on the way out the robbers dropped one piece of jewelry in the street and this was it. It’s very sentimental to me. Just wanted to share.”
While the thieves didn't take off with her necklace, they did end up stealing $11 million worth of other jewelry, including her engagement ring from husband Kanye West.
