What is diamond fluorescence?

Diamond fluorescence is the effect that ultraviolet light has on a diamond. It is not usually noticed by the naked eye. A part of diamond usually can produce blue-white fluorescence and a small part of diamond can produce yellow fluorescence. And it is graded as “none”, “Medium”, “Medium Blue”, “Strong”, “Strong blue” or “Intense blue”. Nearly 30% of diamonds fluoresce to some degree.

Is diamond fluorescence bad?

Some people think the fluorescence is bad, but many customers like the diamonds with fluorescence. It is a matter of personal opinion. What you should consider about diamond fluorescence is its presence and its effect on the diamond. If fluorescence presence causes a diamond to appear hazy or oily, it will be considered bad. And it will be considered good if it enhances the appearance of a diamond. A study of diamond fluorescence performed by GIA suggested that fluorescence has no perceptible impact on the appearance or transparency of a diamond.
