The carat weight is simply how much a diamond weighs, but it must be measured in an industry specific way. A carat is a metric measurement that is equivalent to 0.2 grams, or slightly more than seven thousandths (0.007) of one ounce.Diamond weights are measured to an accuracy of a thousandth of a carat but are given a weight that is rounded to the nearest hundredth. Diamonds weighing over one carat are designated as a decimal number up to the hundredths, such as '1.23 carats.' Such a weight would be expressed as one carat and twenty three points, a point being 1/100 of a carat.A diamond weighing less than one carat is also represented as a decimal, such as 0.72, in which case it would be said to weigh 'seventy two points.'
