Kim Kardashian's former husband, Kris Humphries, has apparently put her 20 carat engagement ring on auction.
The ring, which is worth a whopping 2 million dollars, is listed as Lot 194 "property of a gentleman" and will go up for sale on October 15 at Christie's in New York, the Mirror reported.
A source told Us magazine that Kardashian, who paid for the Lorraine Schwartz ring herself, gave the ring back to the 28-year-old basketball player in 2012.
Humphries was married to the 32-year-old reality star for 72 days in 2011.
