To start, most people don’t really know what fluorescence is! Should you worry about it? Will it affect the look of your diamond? We’ve got you covered.

Around 25% of all diamonds emit some type of fluorescence under longwave UV. This means that under neon lights, diamonds can glow. There are different levels of intensity of the glow: none, faint, medium, strong and very strong. From the diamonds that have some type of fluorescence, a very small percentage will have any impact on your diamond.

When shopping for a diamond, we recommend a fluorescence range between none, faint, and medium for our clients. Within that range, the look of your diamond will not be affected by fluorescence. It won't make your diamond hazy or cloudy -- it will still be bright, white, and vibrant! If you are looking at a strong or very strong diamond, it is important to take it direct sunlight to ensure it does not have a milky, greasy, or cloudy appearance.

Sometimes if you are shopping for a diamond on the lower color scale, a little bit of fluorescence can actually help by making your diamond appear brighter and whiter. Watch our video to see a demo of what the different types of fluorescence look like. 

Fluorescence is nothing to fear if you are within the recommended range. After all, it’s what makes a diamond GLOW! What do you think? Let us know what you think in the comments below!
