Fluorescence in Diamonds
First, lets explain what fluorescence is when it comes to a diamond. Fluorescence is mainly a blueish glow (yellow and orange are possible but rare) that can be seen in your diamond when it is exposed to an ultraviolet light source. The UV source could be the sun or ultraviolet lamps. So if you’re going cosmic bowling or raging at a blacklight party your selfie might pickup some blue teeth and a blue diamond.
Now, diamonds aren’t only effected by their fluorescence under extreme lighting. If you are laying out in the sun, and that colorless diamond you paid an extra few thousand on to make sure it doesn’t have a yellowish tint has strong blue fluorescence, it may appear hazy. If your diamond is in the color range of D-H (colorless to near colorless) a strong to medium blue fluorescence can have a negative effect on your stone. The opposite is true for a diamond in the I-M color range (near colorless to faint yellow). A diamond that has a slight yellowish tint may appear less yellow and more clear if it has that same strong blue fluorescence inside. So, slightly yellowish diamond with strong fluorescence is good, colorless diamond with strong fluorescence is bad. Here’s a chart to help clarify…
Only about 25% of diamonds have any detectable amount of fluorescence in them. But, it is important to keep this quality in mind when purchasing a diamond because the price should reflect the amount of fluorescence. Most diamond certificates that may come with a diamond when you buy it should describe the level of fluorescence if it exists in the stone. If you don’t have your certificate, or your diamond didn’t come with one, and you want to know if it has fluorescence just hold it up to a UV light and see how much it glows.
