Just like anything worth keeping, every diamond is unique. The clarity of a diamond measures the level of flawlessness that any specific diamond has. Internal diamond imperfections are called inclusions, while external imperfections are known as blemishes. Inclusions and blemishes are very common, while only the rarest diamonds are considered flawless. Light is able to pass through uninterrupted in a flawless diamond, which results in a beautiful sparkle.

Experts measure clarity with special equipment. A classic jewelers' tool is the loupe, a small 10-power (10x) magnifying glass. This is the standard magnification when determining diamond clarity. Jewelers will also use gemological microscopes to show you the characteristics of your diamond.

Even diamonds with inclusions and blemishes can be among the most beautiful, especially those with good color and cut. Many inclusions are difficult to see with the naked eye, and some may be minimized by the setting you choose.
