$25,000

Surf in style with the world's most expensive computer mouse, cast from 18-carat white gold and set with 59 diamonds (for a total weight of two carats). Although only two of the limited-edition "Diamond Flowers" have been sold so far, the Switzerland-based manufacturer, Pat Says Now, also makes more affordable mice in all kinds of playful shapes and colors -- from cats and dogs to bikini clad women. The outfit is expanding its high-end offerings with customized diamond patterns -- think your initials or logo -- custom-made upon request.
