What is fluorescence and what difference does it make to a diamond?
Some diamonds emit a subtle blue (or yellow, or even white) glow when exposed to ultraviolet rays – including the sun and fluorescent office lights. Fluorescence in diamonds does not typically affect price nor appearance, although sometimes a very strongly fluorescent diamond may appear ‘milky’ in daylight. Fluorescence may also have a slightly positive influence on the appearance of certain off – coloured diamonds which may increase their beauty.
