Diffused fluorescent lighting helps you evaluate which property?

• A. Fire
• B. Color
• C. Clarity
• D. Brightness

Answer: (D)

How a gemstone handles light and returns it to your eye is what’s being tested here—brightness. Diffused fluorescent lighting provides even illumination with minimal glare, so you can see how effectively the diamond reflects and transmits light across its facets. When brightness is high, the stone looks lively and evenly lit, without dark spots or patchiness that come from leakage or poor faceting. This kind of lighting helps you judge the stone’s light performance rather than its color, fire, or clarity. Color depends on the light’s spectrum, fire comes from dispersion under stronger, more directional light, and clarity concerns internal inclusions that are better seen under different viewing conditions. So diffused lighting is best for evaluating brightness.
