Diamond Clarity

Clarity grade is a measure of the number and size of minor flaws or “inclusions” that a diamond contains. An inclusion is any spot, scratch, bubble, or line that occurred when the diamond was still being formed deep in the earth. Nearly every diamond has inclusions, but most inclusions are not visible to the naked eye. Gem laboratories use a magnifying glass (at 10x magnification) to determine the amount, size, position, nature, and color of the inclusions. The clarity of diamonds ranges from “flawless” to “included”.

Did You Know?You should avoid diamonds with visible flaws that affect their overall beauty or durability, but it is not necessary to select a flawless diamond. To make sure that your diamond has no visible flaws, we recommend stones with a grade of SI2 or higher. However, some SI diamonds can provide great value as many are virtually flawless to the naked eye.

Use the interactive scale below to distinguish between clarity grades.

What makes a diamond sparkle? It is created by the cut of the diamond, which is why you should pay close attention to the first of the 4C’s.

Although diamonds come in a variety of colors, you should know that it is in fact the lack of color, or “whiteness,” that increases the value of a diamond.

Does size matter? Maybe not as much as you might have thought, because carat is actually a measure of a diamond’s weight, not just it’s size.
