Fluorescence
Fluorescence is a special feature of some gems where they glow under ultraviolet (UV) light. It's like having a hidden color that only appears under special lighting. In the jewelry industry, this characteristic can affect a gem's value and is an important factor when grading diamonds and other precious stones. Gemologists use terms like "strong blue fluorescence" or "no fluorescence" to describe this property. This feature is particularly important in diamond grading, where blue fluorescence can sometimes make a slightly yellow diamond appear whiter in daylight.

Example Interview Questions
Senior Level Questions
Q: How does fluorescence impact diamond grading and pricing?
Expected Answer: A senior gemologist should explain how different levels of fluorescence (none, faint, medium, strong, very strong) affect diamond value, discuss market preferences, and explain how fluorescence can both positively and negatively impact a diamond's appearance in different lighting conditions.
Q: How would you train junior staff to properly assess fluorescence?
Expected Answer: Should demonstrate knowledge of proper UV lighting conditions, standardized grading procedures, and ability to create training programs that ensure consistent fluorescence grading across team members.
Mid Level Questions
Q: What equipment do you use to test fluorescence, and how do you maintain it?
Expected Answer: Should be able to describe proper UV lamp usage, maintenance procedures, and safety protocols when testing fluorescence in gems.
Q: How do you document fluorescence observations in laboratory reports?
Expected Answer: Should explain standard terminology, grading scales, and proper documentation procedures for recording fluorescence characteristics in formal gem laboratory reports.
Junior Level Questions
Q: What is fluorescence in diamonds and how do you detect it?
Expected Answer: Should explain basic concept of fluorescence, demonstrate knowledge of using UV light to observe it, and identify common fluorescent colors in diamonds.
Q: What are the different levels of fluorescence intensity?
Expected Answer: Should be able to list and describe the standard fluorescence intensity grades: none, faint, medium, strong, and very strong.
