Clarity is the rarity factor that indicates the degree to which a diamond is free from internal inclusions and external blemishes, called "clarity characteristics". A diamond is given a clarity grade based on the number, nature, size, location and color of the clarity characteristics. Generally speaking, the more inclusions a diamond has, the less transparent it is, and the lower the price. Only very rare diamonds are completely free from inclusions and blemishes all together. These diamonds are called "flawless".

To determine a diamond's clarity grade, it is viewed under 10-power magnification by a trained diamond grader. Diamonds can range in clarity grades from flawless to included. Diamonds may attain the following clarity grades:

A difference between clarity grades is almost impossible to determine with your unaided eye. A microscope or loupe will show you exactly what is inside your diamond.

Inclusions in each diamond are unique and represent individual characteristics that help distinguish each diamond from another.
