Diamonds Grading Criteria

Diamonds are graded using grading criteria known as the "Four C's". These criteria are: color, cut, clarity and carat.

Color refers to the presence or absence of color in white diamonds. Diamond with no color allows maximum light to pass through, colorless diamonds are preferred for their sparkle.

Cut refers to a diamonds reflective quality. Most diamonds are cut with 58 facets. The brilliance of diamonds is heavily dependent on the cut. The different angles and the finish of a diamond determine its ability to reflect light and cause its brilliance and fire. The cut of a diamond can have an impact on its durability as well as its beauty. Cut is probably the most important of the Four C's.

Clarity refers to the inner flaws, or inclusions occur during the formation in most diamonds. Diamonds that are clear create more brilliance and therefore are rarer and highly priced. To be considered "flawless", a diamond must have no surface or internal imperfections visible upon being viewed by a skilled diamond grader using 10 power magnifications.

Carat is the unit of weight by which diamonds are measured. One carat is equal to 200 milligrams. A carat is divided into 100 segments called points. 150 points would equal one and a half carats.

Knowing the "four C's" allows you to compare and purchase the best diamond at a fair price. Shop around and decide what shapes and styles really appeal to you and enjoy your diamond for years to come.
