How Does Your Diamond Glow

GN Diamond wants you to know just what makes your diamonds glow.

Like the very existence of diamonds themselves, fluorescence is an intriguing phenomenon. Commonly found on GIA Grading Reports, about 25% to 35% of all diamonds submitted for grading over the past decade maintain some degree of fluorescence.

What is diamond fluorescence?

When you hear the term ‘fluorescence’ in regard to diamonds, this refers directly to the strength, or intensity, of the diamond’s reaction to long-wave UV, an essential component of daylight. The light emitted lasts as long as the diamond is exposed to the ultraviolet source.

“Diamond fluorescence, in its most simple form, is the effect that ultraviolet (UV) light has on a diamond.” -GIA Blog

What creates diamond fluorescence?

Get excited, chemistry enthusiasts. The culprit for the creation of fluorescence in diamonds is nitrogen. The specific color of fluorescence exhibited is determined by how carbon and nitrogen atoms interact with each other in the diamond itself. (This next prose speaks to the ‘diamond nerds’ out there, like me.)

Sometimes the lattice-like organization of carbon atoms allows spaces within the structure. These vacancies become reserved by awaiting nitrogen atoms. If one atom finds its way in to reserve this open space, a bright orange-yellow fluorescence occurs. The most common combination of this lattice re-positioning is when three nitrogen atoms align adjacent to one another, which will create a blue fluorescence.

Do I want a diamond with fluorescence?

A diamond that fluoresces has the same integrity as one with no reaction to UV. The strength of fluorescence also has no widely noticeable effect on appearance. The decision to opt for a colorless diamond or a diamond with fluorescence is purely a personal choice, determined by your preference.
