Although Crystal Harris was the one to call off her wedding to Hugh Hefner, Hef agreed to let her keep the $90,000 engagement ring. Now she’s auctioning off the 3.39 carat circular-cut diamond at Christie’s in New York next month. Sources told TMZ:

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

if it’s that painful for Crystal to look at, why not just return the ring to Hef? It’s expected to sell for $20,000 – $30,000.
