The Importance of Clarity
Share |

Clarity is considered important in the value of a diamond because of the notion that diamonds with a higher clarity are rarer in nature. Below are some examples of diamond clarity.

Examples of Clarity Grades

Many factors can affect a diamond’s clarity, but having confidence that you are getting the best diamond for your money helps to ensure you are satisfied with your purchase.

Our certified gemologists go through rigorous training and testing to determine clarity, and AGS has even developed a numbered clarity scale to make it easier to understand clarity.

AGS Rock Stars note: You might hear that only diamonds with clarity grades of AGS 7, 8, 9 & 10 (SI2 to I3) should have eye visible inclusions (inclusions that are visible without magnification to the naked eye.) The truth is, eye visibility depends on the size and cut of the diamond, the nature of the inclusions, your visual acuity, and how hard you look.
