Crystal Harris Auctioning Off Engagement Ring From Hugh Hefner!

Crystal Harris has no use for the engagement ring that Huge Hefner gave her so she is auctioning off the ring via Christie’s in NYC for at least $20K. Money looks a whole lot better than a ring from someone you never intended to marry!

A diamond isn’t always forever … sometimes its only for 6 months — especially for Hugh Hefner’s ex-fiancee Crystal Harris … who just put her engagement ring on a pretty famous auction block!

TMZ has learned … the platinum ring, which boasts a 3.39 carat circular-cut diamond — will be auctioned off by Christie’s in NYC next month.

According to the listing, the ring is expected to sell somewhere in the range of $20 -$30k.

Sources close to Crystal tell us … the former Playboy model “couldn’t bear to look at the ring anymore because it brought back bad memories.”

Think how the guy who paid for that rock feels … right, Hef?
