Nearly outblinging her 15 carat Lorraine Schwartz engagement ring, the Kimoji entrepreneur's $4 million, 20 carat ring from Kanye West was one of her most prized possessions. She first debuted the piece at the 2016 MTV Video Music Awards in August. Sadly, the bauble was one of the valuables taken when the reality star was robbed during Paris Fashion Week fall 2016.
