How Diamond Fluorescence Works in Favor of Buyers

Fluorescence as most of you would know is the flaw that gives diamond the blue effect under ultraviolet ray. It is a characteristic that you are alerted about and advised to avoid if you want to buy a good quality diamond. But, if you are open to ideas that can save a few bucks, then here is a way of turning this disadvantage into an advantage. Let’s find out how.

The effect of florescence is not unknown to most educated buyers. We all know what to look for when scoping a diamond under the ultraviolet light. A soft bluish glow reveals itself in diamonds that have fluorescence when exposed under the light. Most buyers are clear till this point. But, do you know what causes that blue glow? It’s the presence of certain minerals, the colors of which when refracted through the facets of the stone take up a blue hue. That makes it a completely natural thing in diamonds. In case you didn’t know this, fluorescence is common in three quarters of all diamonds mined in our planet.

The thing about fluorescence is that it does not show itself in the natural light of the day, or even under high indoor illumination. So, in a general word, it does not affect the appearance of a diamond in any perceivable way. Yet buyers try to steer clear from stones with fluorescence flaw because it is generally seen as an imperfection. But the good news that comes at the heel of this fact is that a fluorescent effect can cause a price drop of up to 15%. This is where fluorescent can work in the favor of a buyer.

Diamonds from the lower color grades like I and below surely contain fluorescence in varying degrees. But what makes it inconsequential is the faint yellow color which cancels out the blue haze of the fluorescence. Aside from canceling each other out, the two blemishes better the face-up tone of the diamond by a full color grade. That, no matter how you see it, is a major advantage for a buyer.
On account of a superior face-up color, even a seller bumps up the price of those stones by 2 to 3%. But if you aim lower, and grab a diamond from the lesser color grades, you will be able to avail a significant discount, even when it appears whiter on the face.
