Carats

A diamonds weight is represented in carats. Carat is a measurement of weight NOT size. Weight impacts the price most dramatically out of the various diamond characteristics. This is why some diamonds have poor cut to retain diamond rough and larger carat size equating to a higher selling price. Diamond size is dependant on your budget and needs to be considered equally with the other characteristics of colour, cut and clarity in order to purchase a quality diamond.

One diamond carat is divided into 100 points; a diamond that is 3/4 of a carat is also 75 points. One carat is the equivalent of 0.2 grams. Diamond carat weight affects the price of diamonds more than any other determinant. A diamond that is double the size of another diamond can be up to four times the price. This significant movement in price is because the relative scarcity of larger diamonds. A combination of a large size (1 carat+) with the best colour (D), best clarity (IF) and excellent/ideal cut is so rare the price is multiplied several times when comparing a similar size with poorer features.
