FAQ

Those who are looking for an answer to the question «Why does my diamond look blue under uv light?» often ask the following questions:

👉 What does a fake diamond look like under black light?

When you place a real diamond underneath an ultraviolet light, the stone with fluorescence in it will turn blue. But it's important to know that this will only happen with about one-third of all diamonds. A fake diamond, on the other hand, will almost never look blue under a black or UV light.

👉 Does strong blue fluorescence make diamond look blue?

In fact a study conducted by the Gemological Institute of America (GIA) determined that fluorescence negatively impacts the visual performance of a diamond in fewer than 2% of instances, in which the level of fluorescence is almost always strong to very strong blue.

👉 Why does a diamond look blue?

Some diamonds fluoresce when they are exposed to ultraviolet (UV) rays from sources like the sun and fluorescent lamps. This can cause them to emit a bluish light or more rarely, a yellow or orangy light. Once the UV light source is removed, the diamond stops fluorescing. 2.

When you stand under blue light or ultraviolet light in the nightclub, your teeth sometimes glow white looks more bright. Similarly, when a diamond is placed under black light, it glows. However, not all diamonds have fluorescence, some are fluorescent free called “None” in the GIA diamond report. Only 30% to 35% of diamonds have fluorescence.

When you stand under a blue light or ultraviolet light, sometimes you can see your whites get brighter or your teeth appear to glow. This is the same effect the diamond has under the UV rays. Fluorescence is the visible light that a diamond emits when it is exposed to the UV rays.

When diamonds have Slight or Faint Blue Fluorescence, for example, they don’t appear cloudy. In fact, the slight fluorescence can make the diamond appear more white. But when fluorescence makes the diamond hazy, the stone is less transparent. Light won’t reflect as well and the diamond won’t be as clear or beautiful.

Hold the diamond in question under a long wave UV light (also called a black light). If the diamond reflects a blue fluorescence, it is most likely authentic. Be aware that while the majority of diamonds on the market will have a blue glow under UV light, high quality diamonds will not.

Fluorescence is when a diamond shows a soft glow under ultraviolet (UV) light. This is caused by certain minerals in the diamond. This effect is totally natural, appearing in a third of all diamonds. Most diamonds with fluorescence will glow blue.

Lab grown diamonds can display fluorescence too and this is caused by submicroscopic structures within the crystal during the growing process. Similar to natural diamonds, blue fluorescence is the most commonly observed color in lab diamonds due to the presence of nitrogen impurities.

Fluorescence is the glow you sometimes see when an object emits visible light. Some diamonds fluoresce when they are exposed to ultraviolet (UV) rays from sources like the sun and fluorescent lamps. This can cause them to emit a bluish light or more rarely, a yellow or orangy light. Once the UV light source is removed, the diamond stops fluorescing. 2.

The other factors are the way the diamond breaks down the incoming light (reflection and refraction - depending on the minute details of cut angles and facet sizes), what that light is (including what is reflected from the surrounding environment), and the way your eye perceives it.

If you are looking at a real diamond, you will typically not be able to read the text through the stone. If you can read the text, the stone you are looking at does not have the proper light dispersion properties a real diamond possesses. Ultraviolet Light: About 30% of diamonds will glow blue under ultraviolet lights such as black light. Fake diamonds, on the other hand, will glow other colors or not at all.

Something does not compute. A diamond of this size, if truly blue natural diamond, is museum quality and wouldn't be available on the open market except for extraordinary circumstances, and the price would make the acquisition of appraisal services, even flying the buyer and the appraiser to the remote location, absolutely trivial.

What color should a diamond be under uv light?

Fluorescence in diamonds is the glow you might see when the diamond is under ultra-violet (UV) light (i.e. sunlight or black light). Approximately 30% of diamonds glow at least somewhat. When exposed to ultra-violet light, these diamonds fluoresce different colors. 99% of the time, the glow is blue, but on rare occasions, diamonds glow white, yellow, green, or even red in color. The GIA grades fluorescence in diamonds as None, Faint, Medium, Strong and Very Strong.
