Ultraviolet Fluorescent Lamp FUV-4

Jewelry Fluorescent Lamp

    Approximatly 1/3 of all diamonds have a tendency to fluoresce when exposed to ultra-violet (UV) light. When diamonds are viewed under a UV light-source, they tend to fluoresce as blue or violet-blue. Natural fluorescence can help a off-colored diamond look like it is a higher grade than it actually does, which is why it is important to identify it.

    Ultraviolet (UV) light rays are beyond the spectrum sensitivity of the human eye. Under an artificial ultraviolet light source, many stones fluoresce or give-off light. The intensity and color of the fluorescence will vary with a short or long wavelength of light. This fluorescence is useful in determining the authenticity of stones.
