Diamond weight is measured in Carats, a small unit of measurement equal to 200 milligrams. Each carat is divided into 100 points. Therefore, a half-carat stone may be referred to as a "50-pointer" or "50-points." Carat weight is the easiest of the 4 C's for gemologists to determine because of the use of sophisticated measuring equipment.

GIA has a diamond “Report Check” you can utilize online. To check your report, simply enter the number on the top of the certification to verify its authenticity. If a certificate is presented from any other grading entity, do some research to make sure it isn’t owned by the person selling you the stone.

One way to look at it is to say that each point equals 0.01 or one-hundredths of a carat. For example, 0.25 means twenty-five one-hundredths. So a 0.25-carat diamond would equal twenty-five points of one-quarter of a carat. Diamond carats are often confused with stone sizes when it is actually a measure of weight.

A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’

If you are buying a diamond that is already set in an existing setting, measuring the millimeter of the diamond will help you estimate the carat weight of the diamond. However, it may be tricky to get it measured accurately.

Then, divide that number by 0.2 to obtain the carat weight of the diamond. For example, if a diamond weighs 0.1 grams, then dividing this number by 0.2 yields 0.5, meaning that the stone weighs half a carat.

A unit of weight for a diamond. Equal to 200 milligrams, or one-fifth of a gram. * Carat is a measure of a diamond’s weight and by itself may not reflect a diamond’s size. * We check diamond from the top because that is how diamonds look like to use when they are set in the ring.

To test the diamond’s refractivity, gently place the stone flat side down onto a page of newspaper in an area with lots of lettering. Ensure the lighting is bright and that no objects or people are casting a shadow on the diamond. If you’re able to read the letters of the newspaper—even if the letters are a bit blurry—the diamond is fake.
