Why do Diamonds that turn blue under ultra violet light?

Diamonds that turn blue under ultraviolet light have trace elements of boron in their crystal structure. These boron impurities absorb ultraviolet light and emit a blue fluorescence, causing the diamond to appear blue under UV light.


What make clothes glow under ultra violet light?

Certain chemicals called phosphors are added to clothes to make them glow under ultraviolet (UV) light. These phosphors absorb the UV light and then re-emit it at a longer wavelength that is visible to the human eye, creating a fluorescent or glow effect.

Fluorescent or neon colors, such as bright greens, pinks, and yellows, tend to show up prominently under ultraviolet (UV) light. These colors appear to glow because certain dyes and pigments react to UV light by emitting visible light.


So I have 2 10 dollar bills in front of me one of them glows under my black light and the other stays a dark shade of purple Why?

The 10 dollar bill that glows under the black light may have security features such as fluorescent ink or security threads that react to ultraviolet light. The other bill likely does not have these security features and thus does not reflect or fluoresce under a black light.

An opaque white appearance under a black light may indicate that the diamond is not a true diamond but could be a simulant or synthetic stone. Natural diamonds typically do not fluoresce strongly white under ultraviolet light. It would be best to have the diamond examined by a professional gemologist for a more accurate assessment.
