Diamond fluorescence is often misunderstood, and many shoppers wonder whether it’s something to avoid. At Martin Busch Jewelers, we believe knowledge is key—so let’s break down what fluorescence really means and when it matters.
What Is Diamond Fluorescence?
Fluorescence refers to a diamond’s tendency to emit a soft glow—usually blue—when exposed to ultraviolet (UV) light. About 25–35% of diamonds exhibit some level of fluorescence, ranging from faint to very strong.
Is Fluorescence Bad?
In most cases, no. For the majority of diamonds, fluorescence has little to no visible effect in everyday lighting. In fact, faint to medium blue fluorescence can sometimes make a diamond appear brighter or whiter.
When Fluorescence Can Be a Concern
Very strong fluorescence may cause a diamond to look slightly hazy or oily—but this is rare and easily noticeable when viewed in person. This is why seeing a diamond before purchasing is so important.
Fluorescence Can Be a Value Advantage
Diamonds with fluorescence are often priced slightly lower, making them an excellent option for buyers who want exceptional sparkle at a better value.
Does Fluorescence Affect Sparkle?
No—cut quality determines sparkle. A well-cut diamond with fluorescence can still be incredibly brilliant.
