Diamond Fluorescence - Can it Really Affect Gemstone Color?

When browsing for a gemstone, diamond fluorescence is a widespread factor that is typically missed. It could be that a lot of consumers aren’t appropriately knowledgeable of this event. Nevertheless, it must not be an factor that’s to be ignored. Let us acquire a seem at this phenomenon and how it can influence your stone.

What Is Fluorescence?
Fluorescence, also identified as picture luminescence, is a attribute of some diamonds which triggers them to glow when exposed to ultraviolet light. This happens when the boron atoms contained in a stone are stimulated by any supply of UV lights, these as all-natural daylight and black lights. The amount of glow that a stone emits will count on the amount of boron atoms it has, and while the bulk of stones fluoresce blue, other hues are feasible. This can vary from yellow, eco-friendly, white, pink and purple, like the Hope Diamond. The abbreviations for describing power of fluorescence are as follows:

• N, NO, NON – No fluorescence


• F, FB, FT, FA – Faint or faint blue fluorescence


• SL, SLB, SLT – Slight fluorescence


• M, MO, ME, MD – Medium or average fluorescence


• S, ST, STB, STG – Powerful fluorescence


• E, EX, EXB, EF – Severe fluorescence

Is This Good Or Lousy?
This phenomenon has caused a lot of debates in the diamond market, and in a lot of cases, affected the pricing of gemstones. The concept has been that diamond fluorescence has a good affect on faint yellow stones, these as all those graded K, L and M. For example, if a yellow stone fluoresces blue, it counteracts with the yellow, building it surface whiter. For this purpose, these decreased-coloured gemstones that glow blue are greater in price than all those that will not glow. On the other hand, the other concept proposed is that fluorescence can have a negative affect on colorless diamonds, these as all those graded D, E and F. When viewed underneath ultraviolet light, a colorless stone that has a medium to powerful glow will seem oily or cloudy. This detracts from the splendor of the diamond, and as a consequence, delivers down it is really price by 10 to 30 percent.

You Be The Choose
In 1997, the Gemological Institute Of The united states (GIA) executed a analyze on the impact of ultraviolet fluorescence on a diamond’s visual appeal. A group of identical graded stones with different amounts of fluorescence were noticed and commented on by contributors. These contributors included trained diamond graders, trade pros (jewelers) and average observers (basic community). The analyze concluded that for the average observer, fluorescence produced no discernible variance. As for the skilled observers (graders and trade pros), they did not concur on the affects of fluorescence. And opposite to the previous theories, the trained/skilled observers most persistently identified that stones which emit a powerful glow were the types with the finest shade.

The base line is, you must not permit diamond fluorescence unduly impact your choice when picking out a gemstone. If the market specialists can not seem to concur and regularly split hairs more than the impact, then it must just be a issue of personalized choice.
