Which term means visible to the unaided eye?

• A. Eye-visible
• B. Face-up (or table-up)
• C. Feather (Ftr)
• D. Fancy cut

Answer: (A)

In diamond grading, the key idea is describing whether inclusions or blemishes can be seen without any magnification when you view the diamond under normal lighting. The term that matches that idea is eye-visible, which means inclusions are visible to the naked eye. This directly answers how noticeable the internal features are to an unaided observer. The other terms don’t describe naked-eye visibility: face-up (or table-up) is about how the diamond sits when viewed from the top, not about visibility of internal features; a feather is a specific type of inclusion, but it’s one feature rather than the overall visibility status; and fancy cut refers to a cut style, not to visibility of inclusions. So the term that means visible to the unaided eye is eye-visible.
