When the diamond is exposed to ultraviolet lighting and emits a visual glow called fluorescence, the glow is usually blue “neon”, and this condition is called “f fluorescence “, and it’s found in more than 30% of the diamond.
Fluorescence does not generally affect the beauty or luster of high-quality diamonds, but it can make some lower-quality colors such as ( I, J, K ، L ) appears foggy, milky, or oily. Therefore, fluorescent diamonds are usually cheaper provided that the negative effect of fluorescence is never easily visible.
The prevailing belief is fluorescence has a negative impact on the appearance of diamonds, however, there are many who believe that fluorescence has no negative effect; Some even confirm that it enhances the appearance of color.
How to be a fluorescent diamond?
Diamonds are crystallized carbon beneath the depths of the Earth’s surface, usually at volcanic sites or sites where volcanoes are ancient. The diamonds become fluoresce, if there are traces of mineral boron present on the ground during the crystallization process. Diamonds can fluoresce in a variety of colors, blue, yellow, green, orange, and white, but blue is the most common.
What are the levels of fluorescence?
According to the GIA gem trade laboratory, there are five levels of diamond: none, weak, medium, strong, very strong. The force of fluorescence is not directly related to color or purity. It is possible for two completely different purity and color levels to show the same level of fluorescence.
