Diamond fluorescence is the visible glow a diamond emits when it is exposed to ultraviolet (UV) light. • How it works : Trace elements trapped inside the diamond crystal—such as nitrogen, boron, or aluminum—absorb invisible UV radiation (found in sunlight and black lights) and release it as visible light. • Prevalence : About 25% to 35% of natural diamonds show some level of fluorescence. • Colors : Blue is the most common color (accounting for roughly 95% to 98% of fluorescent diamonds), though white, yellow, orange, green, or pink can occasionally occur. How GIA Grades Fluorescence The Gemological Institute of America (GIA) and other labs grade fluorescence based on its intensity under long-wave UV light: • None : No glow is emitted. • Faint : A slight, barely noticeable glow. • Medium : A clear, moderate glow. • Strong : A bright and prominent glow. • Very Strong : An intense glow under UV light.

Impact on Appearance and Value • The "Blue-White" Benefit : Blue fluorescence can cancel out faint yellow tints in near-colorless diamonds (grades I through M), making the stone look whiter, brighter, and more colorless in daylight. • The "Milky/Hazy" Risk : In rare cases (less than 1% of fluorescent diamonds), strong or very strong fluorescence can make a colorless diamond (grades D through F) look slightly hazy, oily, or milky in direct sunlight. • Price Effect : Diamonds with strong fluorescence are often priced 10% to 15% lower because of market stigma, even though faint-to-medium fluorescence rarely causes any visible downside. #diamond
