Basketball player Kris Humphries presented Kardashian a 20.5-carat rock when they got engaged, and sources said his now-estranged wife has the option under a prenup clause to buy the ring for its full purchase price.
TMZ said the ring is valued at around $2 million, and, sources say, Kardashian is in love with it.
Kardashian and Humphries have split up just a couple of months after being married in a television-event wedding. TMZ noted that without the prenup, Kardashian would have been able to keep the ring free of charge since she had been officially married.
