This is the prime determining factor in the price of a diamond. As you might expect, the bigger the diamond, the more expensive it will be.
Carats are units of weight measurement. They are used to measure most precious stones, because of their ease. A carat equals 200 grams, and makes expressing stone weight much easier than using grams. Instead of having to label 3 diamonds with weights of 200 milligrams, 207 milligrams and 213 milligrams, the carat provides categories for diamonds to fit into, placing all of these diamonds in the 1-carat range.
Something to keep in mind is that a higher carat weight does not always translate to a larger looking stone. Even among stones of the same shape, other factors (especially cut) can greatly influence the perceived size of a diamond. A cut that gives a diamond a large table (the uppermost flat surface of a diamond) will make a small diamond look bigger. However what you get in perceived size, you lose in brilliance.
Oppositely, a diamond that is cut wide at the girdle (a diamonds widest point) will make a large stone look smaller. There’s not much benefit to the overall appearance of the diamond with this kind of a cut, unless you are specifically looking to make a large stone appear smaller (which is a rare case, indeed).
An important factor in choosing a diamond is the size of the finger that will be wearing the diamond. For someone with thicker, wider fingers, it might make sense to spend extra money to get a larger diamond that is cut to maximize its perceived size. A small diamond will look even smaller worn on large fingers. The opposite is also true. Someone with especially slender fingers can get extra mileage out of a smaller diamond.
The current cost breakdown of the carat scale looks approximately like this: a diamond with a clarity rating of SI1 and color of G at .50 carats will go up approximately $1,100 per carat when raised to the next carat category (.70 – .89 carats). In the next carat range (.90 – .99 carats) the price will go up an additional $800 per carat. In the 1.00 -1.49 carat range, the price per carat rises by about $800 per carat. Another $1,200 per carat is added in the range of 1.50 – 1.99 carats.
