Crystal Harris, who was set to wed the Playboy founder before calling off the wedding, is selling her diamond engagement ring.
Harris’ platinum ring, given to her by Hefner, boasts a 3.39 carat circular-cut diamond.
It will be auctioned by Christie's in New York and, according to the listing, the ring is expected to sell somewhere in the range of $20,000-$30,000.
Sources close to Harris told TMZ.com the former Playboy model: “Couldn't bear to look at the ring anymore because it brought back bad memories.'
