Diamonds are not sold by weight, Diamonds are sold by grade. Much like you can have a rare coin worth 1000 dollars or 100,000.00 depending on it's quality.

Carat is a unit of mass. While the value per carat is variable depending on the specifics, diamonds are indeed sold by weight, and the price (for gem-quality diamonds, at least) is not linear (e.g. a 2 carat diamond is not simply twice the price of a 1 carat diamond)
