A 1.08 carat stone would be described as ‘one point oh eight carats.’Īll other points of comparison being equal, diamond price increases with diamond carat weight, because larger diamonds are more rare and more desirable. For instance, a diamond that weighs 0.25 carats could also be referred to as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals.
