In the state of Wisconsin, they have developed a policy under which, after a certain period of time, items including diamond jewelry are put up for auction on eBay.

Robert Charlton, a promiscuous businessman, had trouble keeping faithful to his wife, Elizabeth Charlton. Luckily for her, whenever Charles indulged in an extramarital romp, he felt guilty - guilty enough to buy her expensive jewelry, including some magnificent diamonds. This implicit agreement satisfied both spouses and soon enough Elizabeth Charlton was boasting quite a collection. By the time her husband died at the age of 63, after 25 years of marriage, Elizabeth was in possession of 43 items. When Mrs. Charlton passed away in 2006, at the age of 90, her jewels were passed on to her daughter Marie, who elected to sell them at auction. Last week, the contents of Elizabeth Charlton’s jewelry box sold for £286,000 - approximately £6,000 per tryst.
