Word has it, Crystal Harris, ex-fiancee of Playboy creator, Hugh Hefner is putting her engagement ring on the auction block. The ring is rumored to be valued at $90,000, but it’s estimated to go for about $25,000. After the split, Crystal was allowed to keep the ring as well as a Bentley purchased for her by Hef. Right after the split, she took to People Magazine and told them, “It doesn’t make sense to have so many women around but still have a marriage…so it was the right thing. I wasn’t the only woman in Hef’s life and it was going to stay that way after the marriage.” And it seems she was probably correct in that assumption because shortly after their split, he began dating a friend of hers. So, now she’s saying there are too many bad memories attached to the ring, and according to TMZ, the 3.39 carat ring will be auctioned off by Christie’s sometime next month. Well, there you have it. Would you sell your engagement ring given to you by Hugh Hefner?
