I'll explain it here. But feel free to contact me with any question you may have or quotation you may require.
Fluorescents can do much to enhance or detract from a diamond's overall appearance.
Before deciding on a diamond determine whether it has fluorescence or not and be sure to gage its effect on brilliance and appearance to your own personal requirements. The electrons of the carbon molecules of the diamond are excited by the radiation and emit the excess energy in returning to their original state. This emission, unlike phosphorescence, ceases as soon as the source of excitation is removed, and so the glow disappears. The light emitted is generally of a lower frequency than the radiation absorbed, which is generally ultraviolet light. Picture yourself proposing marriage in a romantic, candle-lit setting and noticing that your precious diamond engagement ring appears to be glowing in the dark.
