The Los Angeles Times said Christie's is expecting to get $20,000-$30,000 for the ring that Crystal Harris kept after her engagement to the 85-year-old Playboy mogul was broken off this summer.
The rock is measured at 3.39 carats and was touted at about $90,000 when Hefner presented it to Harris in December. Harris tried to return the ring when the wedding was called off, but Hefner declined the gesture, the Times said.
