Is Diamond Fluorescence A Good Or Bad Thing?

Diamond Fluorescence is a topic that is both interesting and surrounded by many misconceptions. Some people believe that you should avoid fluorescent diamonds at all costs. Some people have also never have of diamond fluorescence previously.

So, is diamond fluorescence a good or bad thing?

The correct answer is: It depends.

Read on for a further and more detailed explanation.

What Is Diamond Fluorescence?

Diamond fluorescence refers to the response of a diamond to ultraviolet light. Ultraviolet light is usually found in sunlight, night clubs, and fluorescent bulbs.

Diamonds contain various elements including boron, aluminum, and nitrogen. Upon exposure to UV light, these elements absorb that energy and jump to a higher state on energy. These elements have to emit all the excess energy for them to remain in a physically stable state. They achieve this by emitting light that is perceived as fluorescence.

The commonest fluorescence color diamonds emit is blue and it applies to about 98 percent of all fluorescent diamonds. However, some diamonds have pink, green, yellow, or white fluorescence. Ultimately, the color of the fluorescence is determined by the physical make-up of the internal atomic structure of the diamond.

When Is Fluorescence Good Or Bad?

Fluorescence can be beneficial for several reasons. First, fluorescent diamonds are about 10 to 15 percent cheaper. In addition, they also face up whiter and under UV light, the fluorescent effect can be quite impressive and can make the diamond appear very special.

In the same breath, fluorescence can be also negative since it causes haziness in diamonds sometimes. This haziness translates into milky spots that are visible to the naked eye in the diamond. These diamonds are also known as overblue diamonds.

This is why diamond fluorescence being a good or bad thing is highly relative. If the fluorescence doesn’t cause haziness then the fluorescence would be beneficial.

The truth is that diamonds that have blue fluorescence have a somewhat bad reputation and due to this, they are usually cheaper. However, this bad reputation is totally unfounded.

The problem started a few decades back when the blue fluorescence diamonds known as ‘blue white’ diamonds were sold in the market at a premium price. While it originally referred to high quality diamonds, salespersons used this to market blue fluorescence diamonds of inferior quality. The result was the Federal Trade Commission (FTC) banning the descriptive ‘blue white’ label. Ever since this happened, blue fluorescence diamonds have had a bad reputation.

Are Fluorescent Diamonds Hazy, Milky, or Oily?

Fluorescence is of many grades namely, very strong, strong, medium, faint, and none.

Very strong/strong blue fluorescent diamonds are usually hazy

Medium blue fluorescent diamonds are not usually hazy

Faint blue fluorescent diamonds are usually never hazy

What is means is that you can always take a diamond that has faint fluorescence since it makes no difference to the diamond. In addition, you will get to save some money on the diamond.
For K, J, I, or H color graded diamonds you need to consider medium blue fluorescence. This has the effect of making the diamond seem whiter. When you submit the diamond to sunlight the effect will be particularly pronounced. From the ranges D to F there is no such effect of the color of the diamond appearing whiter.

Considering that very strong or strong blue fluorescence normally makes the diamond appear hazy, it is not advisable to buy such a diamond unless you first inspect it. Diamonds within the D to F range are particularly prone to appearing hazy especially when combined with very strong or strong fluorescence.

Why Is There Much Confusion Surrounding Fluorescence?

A study performed in 1997 by GIA is the main source for the confusion on diamond fluorescence. The study concluded that fluorescence has no overall effect on transparency or color appearance.

However, the same study noted that its observations exhibited a clear trend for faintly fluorescent diamonds to be regarded as being more transparent than the strongly fluorescent stones.

In addition, the study does not hide the fact that half of study participants noticed a difference in terms of transparency between fluorescent and non-fluorescent diamonds.

The study is clearly full of contradictions and not at all representative. Therefore, if somebody tells you that GIA has proven that fluorescence has no negative effect, you should think twice.

Benefits Of Blue Fluorescent Diamonds

One of the major benefits of blue fluorescent diamonds is that they are usually cheaper than comparable diamonds without the fluorescence.

What’s more, you will get to have diamonds that exhibit blue fluorescence. Under normal lighting conditions, you might not be able to tell the difference. However, once the diamond is exposed to some fluorescent lighting, it will start to shine in an icy blue way.

Final Thoughts

The question on whether diamond fluorescence is a good or bad thing is quite a complex one. In the end, it all comes down to a matter of preference whether you prefer a diamond with blue fluorescence or simply a regular once. Both types of diamonds are good enough.

The blue fluorescence of diamonds can definitely sprinkle some soul into the diamond to make it stand out even more. It will be entirely up to you whether you buy a diamond with blue fluorescence or not. Go here for some more information on the issue.

If you follow the guidelines provided in this article, you will surely have a diamond that you will get to enjoy for a long time.

Why should you choose a Hearts and Arrows diamond?

The hearts and arrows pattern is a very popular option for a number of jewelry items since this diamond cut allows for an optimal reflection of natural light. The pattern gets its name from the shape that can be observed with a special tool.

The diamonds and arrows shapes are too delicate to be visible to the naked eye but looking at one of these diamonds under a Firescope reveals a pattern with arrows at the top of the diamond and a pattern with hearts when the diamond is viewed from the bottom.

This trend originated in Japan in the late 1980s. The hearts and arrow cut is not very different from other popular diamond cuts but it tends to reflect more light, which is why it quickly become extremely popular in Japan throughout the 1990s. However, a heart and arrow pattern is not always a guarantee that the diamond will be well-cut since this effect is difficult to realize.

Why are they so popular?

Diamond Polishing of a Hearts and Arrows DiamondHearts and arrows diamonds look best when the cut is perfectly symmetrical. In fact, this applies to any cut of diamond since a symmetrical cut will reflect more natural light and make the diamond look shinier and more transparent.

Ideally, a diamond with a round cut and a hearts and arrows pattern should have eight hearts and eight arrows. These are the ideal proportions for a symmetrical cut and an optimal reflection of natural light.
Shoppers often believe that a hearts and arrows diamond is more valuable than other cuts because this pattern is more difficult to realize and sounds more complex. This is not entirely true since many other factors influence the value of a diamond. A hearts and arrows pattern that is not perfectly symmetrical or that doesn’t include an ideal number of hearts and arrows will not make a diamond more valuable than another similar gem with a different cut.

How to evaluate the quality of a hearts and arrows diamond?

However, because this pattern is difficult to realize and because there was such a strong demand for it throughout the 1990s, it is fairly easy to find a high quality cut since this pattern was often reserved for the best diamonds available. In most cases, a lot of care was put into cutting these diamonds.
Diamonds with perfect SymmetryThe presence of this pattern is often mentioned as a note on a diamond’s grading papers. However, there usually isn’t any information regarding the quality of this pattern and the presence of the hearts and arrows pattern isn’t a guarantee of the quality of the cut of the diamond.

This is why it is always best to look at one of these diamonds through a Firescope to see the pattern for yourself if you are thinking about purchasing one.
Hearts and arrows diamonds can be a very interesting choice because this pattern is associated with Cupid and with love. This is perfect if you want jewelry for a romantic gift. Besides, the round cut is a very popular one and will work with a large number of materials and settings if you are thinking about a ring or a necklace.
Even though these diamonds are often presented as being more valuable than others because of the presence of this pattern, it is important to keep in mind that other factors are more important than the presence of the hearts and arrows pattern when shopping for a diamond.

You need to look at the quality of the cut, the carat size, the presence of flaws and the color of the diamond. If you want to get a diamond with the hearts and arrows pattern, look for a diamond with a good cut and symmetry and make sure the pattern was well-realized. You should also review the grading paper of the diamond to find out about any flaws and make sure the diamond is colorless.

In the end, a diamond with the hearts and arrows pattern is ideal for a romantic gift due to the theme of this pattern. However, it is important to look at other factors and to make sure that the quality and symmetry of the cut is there since the presence of the hearts and arrows pattern does not mean that the cut of the diamond will be perfectly symmetrical and will reflect the light in an ideal manner.
