The American Model and Playboy Playmate Crystal Harris is set to auction the engagement ring that Hugh Hefner presented to her when he proposed last year. Hugh proposed to Harris last Christmas. Harris stated in an interview with People Magazine – Hugh presented the engagement ring in a Little Mermaid box, as it’s her favourite movie. Although Harris seemed to be happy and excited about the engagement, she managed to play the role of ‘run-away-bride’ five days before the wedding, saying that she got cold feet. The engagement ring is set in platinum and is 3.39 carats with a full set of diamonds all the way round the band. The ring is set to go on auction at Christies Auction House in New York and originally cost Hefner around £58 thousand. Unfortunately, for Crystal the engagement ring is only estimated to receive less than half its original price at around £12 to £19 thousand.
