Crystal Harris has put her engagement ring from Hugh Hefner up for sale at Christie’s auction house in New York.

The Playboy model and former girlfriend of Hefner called off their wedding just days before the ceremony was planned.

And now the classy broad has put her 3.39 carat diamond engagement ring on the auction block for between $20,000 and $30,000.

A source said Crystal “couldn’t bear to look at the ring anymore because it brought back bad memories”.

On the auction house’s website, the listing reads: “A diamond ring. Set with a circular-cut diamond, weighing approximately 3.39 carats, to the circular-cut diamond hoop, mounted in platinum.”

Do you think Crystal is selling the huge rock over “painful memories” or the ho just needs some money?
