Calvin and Kelly Klein (7 of 10)
They say jewelry is a bad investment but it depends on what you buy. Calvin Klein, who bought jewels belonging to the Duchess of Windsor for Kelly Klein made quite a return on his investment. The collection of natural pearls the couple put up for sale brought in $4.82 million, far above the $3.1 million high estimate. I hope whoever bought it wears it, wearing pearls helps them keep their luster. 23/09/08
