Flawless
No inclusions or blemishes visible at 10× magnification to a skilled grader.
Diamond Clarity,
explained clearly.
Clarity describes the relative absence of internal characteristics (inclusions) and surface characteristics (blemishes). The grade is only one part of evaluating a diamond—the location, type and visibility of characteristics matter too.
Internally Flawless
No inclusions visible at 10×; only blemishes are present.
Very, Very Slightly Included
Minute inclusions that are difficult for a skilled grader to see at 10×.
Very Slightly Included
Minor inclusions observable at 10× but generally considered small.
Slightly Included
Noticeable inclusions at 10×; visibility to the unaided eye depends on the individual stone.
Included
Obvious inclusions that may affect transparency, brilliance or durability.
Buy the stone, not just the letters.
Two diamonds carrying the same clarity grade can look different. Compare the full grading report, images/video, proportions and the actual appearance of the stone. For significant purchases, use an independent grading report from a recognized laboratory and verify the report with the issuing laboratory.
