Kim Kardashian, the newly blonde star, is making more headlines in 2013. The Playboy favorite's ex-husband Kris Humphries will probably sell Kardashian's engagement ring. 

According to Hello! Magazine, the NBA baller has reportedly struck a deal with auction house, Christie's to anonymously sell the sparkler in an upcoming October "Bright and Beautiful" auction.

Though Humphries has not come out publicly to announce his plans to formally sell the ring, many people have speculated that one of Christie's listed items is indeed Kardashians' old ring. The finger bling is currently listed as the property of a "gentleman," reported MailOnline.  

The ring is an impressive Lorraine Schwartz 16.21-carat rectangular cut diamond, with a 1.80-carat diamond on both sides, according to Hello!

The sparkler is reportedly worth between approximately $251,964 to $424,377. The estimated $424 figure is less than a quarter of the price that Humphries supposedly spent on the ring at the time the couple got engaged.

Kardashian and Humphries were married for only 72 days in 2011. The "Keeping Up with the Kardashians" star filed for divorce, and become pregnant with North West when the divorce was settled.

Kanye West's girlfriend, who gave birth to North in June, had lost the ring to her former husband in their divorce settlement after an 18-month battle.

Reportedly, Humphries had wanted an annulment, claiming the marriage was based on fraud and that Kardashian only married him for her "KUWTK" reality TV show at the time.
