Fluorescence can be good or bad: it can improve a diamond’s color or make the diamond look hazy. … In fact, the slight fluorescence can make the diamond appear more white. But when fluorescence makes the diamond hazy, the stone is less transparent.
Do you want fluorescence in a diamond ring?
If you’re looking at diamonds in the D-F range, we recommend purchasing one without fluorescence. Even faint fluorescence is going to add a dash of blue to your otherwise white stone. Colorless diamonds are some of the biggest fluorescence culprits due to their ultra-clean appearance.
What is the best fluorescence for a diamond?
It is actually recommended to consider fluorescent diamonds in I, J, K or L colors. The lower colors may visually appear half or one grade higher as a result of the fluorescence. More important fluorescent diamonds have about a 10% to 15% discount against Faint or None fluorescent diamonds.
Is strong fluorescence in a diamond 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.
Does diamond fluorescence affect price?
Sometimes, a diamond’s fluorescence will have no effect on its price, while at other times it will. Colorless diamonds, those with a color grade of D-F, are sold at a discount if they have a fluorescent glow underneath a UV light.
Why do diamonds have fluorescence?
Fluorescence occurs in some diamonds when they are exposed to the concentrated radiation of a UV lamp. Submicroscopic structures in the diamonds cause them to emit a visible light, a fluorescence, which is commonly blue in colour.
What is most important in a diamond?
Out of the 4 C’s of diamonds, the cut of the diamond is the most important. This is followed by color, clarity, and carat weight.
Do Lab diamonds have fluorescence?
As a final note on fluorescence, lab-grown diamonds (other than fancy color lab-grown diamonds) never have fluorescence. We think in time this fact could make fluorescence in a natural diamond a more desirable and valuable trait since it serves as a natural differentiator to lab-grown diamonds.
What is blue fluorescence in a diamond?
Fluorescence refers to a diamond’s tendency to emit a soft colored glow when subjected to ultraviolet light (such as a “black light”). … Because the fluorescent glow is usually blue (which is the complementary color to yellow) fluorescence can make diamonds of I-M color appear up to one grade whiter.
What makes a 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.
What is the highest color grade a diamond can have?
The highest color grade for a diamond is “D”. “D” color diamonds are very rare and not commonly found in traditional jewelry. Most diamonds used in jewelry have a slight presence of color.
Is medium fluorescence bad on a diamond?
Fluorescence is your friend, not foe because it can lower the price of the diamond by 4-10%. The price of a diamond is not significantly affected if the diamond has medium blue or faint fluorescence. In some cases, diamond fluorescence might affect the overall appearance of the diamond.
Is color or clarity more important?
The color grade is more important than the clarity grade because cushion-cut diamonds tend to retain a lot of color. … Because of this, you can go as low as SI1 or SI2 on the clarity scale, and the diamond should still appear flawless. If you are shopping for a radiant diamond, prioritize color over clarity.
How much should you spend on an engagement ring?
General Rule: You should spend at least 2 months salary on the engagement ring. If, for example, you are making $60,000 per year, you should spend $10,000 on the engagement ring.
