Fluorescence
Diamond fluorescence refers to the intensity of a coloured glow (usually blue) that is visible when a diamond is exposed to UV light. In some instances, diamonds with strong fluorescence may look milky and lifeless in daylight, but in most cases, the appearance of a diamond with strong fluorescence is rarely affected. Diamonds with none or a faint fluorescence are rarer than those with a strong or very strong fluorescence.
The degree of fluorescence can vary as around one-third of all diamonds show some fluorescence, with 95% exuding a blue colour – though green and yellow fluorescence diamonds can also be found, though much rarer than those with a blue hue.

Fluorescence is one indicator or grading variable for a diamond, but its presence does not necessarily affect how a diamond looks.
Grading Fluorescence
Fluorescence ranges from none through faint to medium, strong and very strong. A diamond with a strong or very strong fluorescence can sometimes have a milky appearance, although this is exhibited by less than 2% of diamonds with a strong or very strong fluorescence grade. Rest assured that every diamond that passes through our workshop will be twice-inspected to ensure the brightest light refraction with no milkiness.
At Taylor & Hart, we recommend diamonds of all fluorescence grades. Every one of our diamonds are twice-inspected by our talented team and we’ll only offer diamonds that carry the maximum possible brilliance.

Our consultants are available to help you to better understand the importance of fluorescence in a diamond and how it can affect the look and feel of your diamond ring.
