The fluorescence of a diamond is created when the exposure to ultraviolet (UV) light gives diamonds a distinctive glowing blue coloration. Being that it is not directly related to color the fluorescence may vary from very weak to very strong.
Odly enough, the GIA chose to start the grading system with a “D” instead of an “A”? this was done because multiple other systems existed before they created their grading system. One system that existed was based on an A, B, C, etc. format and another was based on an agricultural type of format: A, AA, etc. So, in an effort to avoid any confusion the GIA simply decided to start out new by not using previous terminology to avoid this, their grading scale begins with “D”.
Tomorrow we will cover the fourth and final of the 4C’s in our diamond education series. Its always a good thing to know a little something especially about jewelry. Please feel free to like our page and leave any questions or comments.
