Eye-Visible is defined as what in diamond grading terms?

• A. Visible with magnification only.
• B. Visible to the unaided eye, without magnification.
• C. Visible under UV light only.
• D. Not visible under any standard examination.

Answer: (B)

Eye-Visible means flaws inside a diamond are visible to the naked eye, without any magnification. That’s why the best choice is the one that says you can see the inclusions or blemishes with unaided eyes. It isn’t about what you can see only under a loupe or microscope, and it isn’t about fluorescence under UV light. If an issue would require magnification to be seen, it wouldn’t be described as eye-visible. Likewise, not being visible under any standard examination would imply a flawless appearance, which contradicts the concept of eye-visible. In practice, eye-visible inclusions often influence the perceived clarity and value of a diamond.
