Which cut factor is most likely to cause a dull, hazy appearance if poor?

• A. Table percentage
• B. Crown angle
• C. Pavilion angle
• D. Polish quality is poor.

Answer: (D)

Polish quality governs how smoothly the diamond’s surface reflects light. A well-polished diamond has a smooth, mirror-like surface that lets light bounce cleanly from facet to facet, producing bright, crisp reflections. When polish is poor, tiny scratches and a rough surface scatter light in many directions, dulling the overall brilliance and giving a hazy, washed-out look.

Other cut factors like table size and the angles of the crown and pavilion influence how light travels through the diamond and can affect brightness and fire, but if the polish is bad, that rough surface remains the dominant cause of a dull, hazy appearance even when the angles and proportions are close to ideal.
