About the Carat Weight

The carat weight measures the mass of a diamond. One carat is defined as 200 milligrams. The point unit—equal to one one-hundredth of a carat (0.01 carat, or 2 mg)—is commonly used for diamonds of less than one carat.

All else being equal, the price per carat increases with carat weight, since larger diamonds are both rarer and more desirable for use as gemstones. The price per carat does not increase linearly with increasing size. Instead, there are sharp jumps around milestone carat weights, as demand is much higher for diamonds weighing just more than a milestone than for those weighing just less. As an example, a 0.95 carats (190 mg) diamond may have a significantly lower price per carat than a comparable 1.05 carats (210 mg) diamond, because of differences in demand. The chart below shows the size of several diamonds compared to their carat weight.

Total carat weight (TCW) is a phrase used to describe the total mass of diamonds or other gemstone in a piece of jewelry, when more than one gemstone is used. Diamond solitaire earrings, for example, are usually quoted in TCW when placed for sale, indicating the mass of the diamonds in both earrings and not each individual diamond. TCW is also widely used for diamond necklaces, bracelets and other similar jewelry pieces.

What Carat Weight Should I Choose?

When deciding which carat weight to choose, there are several factors to consider. For instance, when selecting the carat size for a ring, you should take into account the size of the ring setting and the size of the ring finger. Here are a few other points to consider:

  • As we mentioned earlier, the price of diamonds can increase significantly around milestone carat weights, such as at 1.05 carats or 2.55 carats.
  • The size of the ring finger can significantly affect the appearance of the ring. For example, a ring placed a size 5 ring finger will appear larger than a ring placed on a size 9 finger.

When shopping for a ring, it is important to know the size of the finger that the ring will be placed on. Once that is known, we welcome you to visit one of our showrooms to compare diamonds of various carat weights for that specific ring size.
