Crystal Harris Auctioning Off Engagement Ring

Although her love life didn’t go as planned, Crystal Harris' financial situation is about to get better.

Hugh Hefner's former fiance is putting her estimated $90,000 engagement ring on the auction block at Christie’s in New York City.

The 3.39 carat diamond ring is expected to pull in between $20,000 and $30,000.

“[Crystal] couldn’t bear to look at the ring anymore because it brought back bad memories,” a source tells TMZ.
