DIAMOND FLUORESCENCE

GUIDE TO DIAMOND FLUORESCENCE

Although it is often misunderstood, diamond fluorescence is a naturally occurring phenomenon that can influence a diamond’s visual appeal under a certain lighting. Under ultraviolet (UV) light, such as sunlight or blacklight, some diamonds emit a blue glow. This glow is called fluorescence, and while it doesn't affect the structural integrity or basic value of the diamond, it can affect appearance, sometimes subtly and sometimes noticeably. At Thom Duma Fine Jewelers in Warren, Ohio, we help clients understand how fluorescence may impact a diamond’s beauty and value. Read on to learn more about diamond fluorescence myths and how it plays a role in choosing the perfect one.

MYTHS OF DIAMOND FLUORESCENCE DISPELLED

There are several myths about diamond fluorescence, one of which is that all diamonds fluoresce, while the truth is only about 25–35% do, according to GIA. So, there’s a strong chance the diamond you’re eyeing doesn’t fluoresce at all. Another misconception is that you can always see fluorescence. In reality, it only appears under ultraviolet or high-energy lighting like tanning beds, lasers, or black lights. Definitely not in everyday lighting. It’s also false that diamonds only fluoresce blue. While blue is the most common, diamonds can emit orange, red, green, yellow, or white fluorescence depending on atomic structure. Understanding these myths helps eliminate confusion and ensures that your diamond decision is based on facts — not false assumptions.

Fluorescence isn’t part of the 4Cs, but it is a listed characteristic on GIA grading reports. These reports describe fluorescence intensity as None, Faint, Medium, Strong, or Very Strong, adding the color only when it's Medium or stronger. Fluorescence doesn’t cause haziness, but it may enhance pre-existing haziness in rare cases where light-scattering defects already exist. Most diamonds, even with strong fluorescence, will not appear cloudy. Still, it’s smart to view any fluorescent diamond in person under varied lighting. Personal preference plays a major role here: some people love the glow, others don’t. Trust your eyes, compare, and choose what truly appeals to you.
