Kim Kardashian's Engagement Ring From Kris Humphries Sells At Auction

Kim Kardashian's gigantic engagement ring from ex-husband Kris Humphries has been sold at an auction.

Us Weekly confirmed that Kardashian's 20-carat ring sold at a Christie's auction on Tuesday for a whopping $620,000 to an anonymous buyer. Bidding started at $200,000. With the auction house's markup, the total price will come to $749,000 for the bauble once worn by the reality starlet.

The Lorraine Schwartz-designed ring features a 16.21-carat rectangular-cut center stone with an I color and VS1 clarity, according to Forbes. Two 1.8-carat trapezoid stones bookend the massive rock. It cost Humphries $2 million at the time of their 2011 engagement.

News of the auction first surfaced in September. Christie's listed it as the 'Property of a Gentleman' and estimated it could sell for up to $500,000. It was later revealed to be the property of the Boston Celtics player.

'The ring is indeed Kris' property that he received through his marriage dissolution,' Humpries' rep said in a statement to E! News at the time. 'He has long-since moved on and is very much looking forward to a successful auction at Christie's on Tuesday, and of course to returning to the court this upcoming NBA season as a Boston Celtic.'

Apparently, Kardashian was happy to be rid of the ring (even though she said it was 'the most beautiful thing' she had ever seen after the proposal).

' Kim has been waiting for the day he would auction it,' a source previously told Us Weekly. 'Everyone always asked what Kim did with the ring -- she silently gave it back over a year ago! And Kris waited until the divorce was final to sell it.'

A portion of the proceeds from the auction will be donated to charity, Forbes reported.
