Diamond fluorescence\u00a0refers to the diamond tendency to disperse a soft bluish glow when exposed to\u00a0ultraviolet light.\u00a0 \u201cA diamond should not have\u00a0strong fluorescence<\/i>.\u201d That\u2019s what is often claimed by many\u00a0diamond experts. However, we have got to be careful with this statement: faint or moderate fluorescence does not affect the diamond\u2019s look, which is proved by a\u00a0GIA study. Moreover, some customers even prefer a\u00a0faint fluorescence, because it balances the yellow color of some of the less expensive stones.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What is diamond fluorescence?<\/h4>

Diamonds have many properties and characteristics. The natural blue fluorescence is one of them. When gem-grade diamonds are exposed to\u00a0ultraviolet light<\/a>, electrons in the diamond crystal excite and a bluish glow can be visible. This phenomenon occurs in a third of all gem-grade diamonds.
The fluorescence is only visible under the black light while recent (GIA) studies have proved that it doesn\u2019t influence the appearance of the diamond. In earlier times people didn\u2019t even want to buy diamonds with fluorescence. While they were a trend in the fifties under the name “blue-white diamonds”, demand dropped in the seventies.<\/p>

Diamonds with fluorescence can change the diamond color sometimes because the UV radiation is also a component of daylight and is present in the fluorescent place. Note that the blue shine is often desirable – it makes yellow diamonds whiter.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The effect on the diamond value<\/h4>\n

You can find the \u2018fluorescence indication\u2019 – inert, faint, negligible, medium – on different diamond reports such as the GIA diamond reports. Diamonds with a strong fluorescence are priced lower than diamonds without fluorescence.
In general, diamonds with colorless<\/a> grades (D-E-F) or near-colorless grades (G-H-I-J) are cheaper when they disperse fluorescence. Faint yellow grades (K-L-M) are higher in price when exhibiting fluorescence.<\/p>\n

However, it is often said that fluorescence has a negative impact on colorless diamonds and a positive impact on faint yellow diamonds, you don\u2019t have to influence your choice too much based on this information.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
