Kim Kardashian`s engagement ring listed for auction

London: Reality TV star Kim Kardashian`s USD two million engagement ring is reportedly set to go under the hammer.

Kardashian, 32, was married to NBA player Kris Humphries for 72 days and now the 20-carat ring is for sale with a percentage going to charity, reported Daily Mirror.

The former husband of the socialite is said to be trying to sell her ring , which she returned to him a year ago.

"It`s 100 per cent Kim`s ring. She gave it back a year ago. Kim apparently paid for the Lorraine Schwartz ring herself but gave it back to Kris over a year ago," a source said.

It`s now listed as Lot 194 and will go up for sale on October 15 at Christie`s in New York.

The catalogue notes apparently say a proportion of the cash made will go to an unnamed charity.
