AdministratorWhat does medium blue fluorescence mean?
A medium blue fluorescent diamond color can even help counteract any yellowish tint the diamonds may have and can make them appear much whiter. In effect, this will make the diamond color and appearance an entire color grade higher.
What is medium blue fluorescence in a diamond?
Fluorescence is an invisible glow that a diamond emits under UV rays. GIA uses the None, Faint, Medium, Strong, and Very Strong scale to determine its intensity….What is Fluorescence in a Diamond? Faint to Strong Blue Scale.
| Fluorescence | Things to Consider |
|---|---|
| Medium Blue | D-E Color – Fair, 6-8% discount. F-G Color – Good, 2-5% discount. H and Above – Very Good, 0-2% discount. |
Is fluorescence in diamonds bad?
In most cases fluorescence is simply an identifying characteristic and not a performance characteristic, and is therefore NEITHER good nor bad. In some cases, strong or very strong fluorescence can make a diamond appear cloudy, diminishing its transparency and eye appeal.
What do fake diamonds look like under UV light?
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.
Do fake diamonds have fluorescence?
The presence or absence of fluorescence should not be used as a DIY test to determine if your diamond is real. First, not all natural diamonds fluoresce under the standard UV lamp used by gemologists (see Myth #1). Second, some synthetic or lab grown diamonds do fluoresce to these wavelengths.
Why does my diamond have a blue tint?
“Is faint fluorescence OK in a diamond?” Yes, it’s no big deal. It can even make a diamond’s color look better. Find out more below. “Why does my diamond look blue in sunlight?” Because it has strong fluorescence.
Why does my diamond look blue?
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.
Why is my diamond glowing in blacklight?
Diamonds glow in black lighting due to a phenomenon called fluorescence and roughly 35% of natural diamonds exhibit some degree of this effect. In nature, the presence of certain chemical impurities within the diamond’s composition triggers this glowing effect in the presence of an ultraviolet light source.
What is a medium blue fluorescent diamond color?
A medium blue fluorescent diamond color can even help counteract any yellowish tint the diamonds may have and can make them appear much whiter. In effect, this will make the diamond color and appearance an entire color grade higher.
Is blue fluorescence the strongest color?
No, while blue is a dominant feature of fluorescence, there are also yellow, orange, red, white, and green fluorescence colors. The other colors are usually less desirable and least preferred compared to blue. How bad is strong blue fluorescence?
What is the effect of blue fluorescence on a diamond?
2) Positive effects: blue fluorescence can often be a positive factor in diamonds with a yellow tint (H, I, J colors or lower grades). This is because yellow is a complementary color to blue, thus making a diamond appear whiter than its actual color.
How much is the discount for blue fluorescence?
In our opinion, the discount should be up to 2% for faint fluorescence, up to 5% for medium blue fluorescence, up to 12% for strong blue fluorescence and up to %18% for very strong blue fluorescence. Medium blue fluorescence might enhance the color of your diamond if it is within the H-L range or higher.
