Another characteristic that does not affect the colour grade of a diamond but is worth keeping in mind is fluorescence This characteristic refers to the diamond’s ability to fluoresce under ultraviolet (UV) light. The most common source of UV is a black light. When exposed to UV light, many diamonds will give off a distinctive glowing blue coloration. Although fluorescence may be displayed in various colours, blue is the most common in diamonds. The fluorescence of a diamond is defined by its intensity as either None, Faint, Medium, Strong, or Very Strong.
