Many people want their diamond to have no fluorescence. Why? It is said that fluorescence can cause a milky or hazy appearance in the diamond. But did you know that is only a very small percentage that has this effect. Fluorescence can actually have a positive effect in most diamonds by making them look whiter. In Bill Boyajian of GIA's article "The Impact of Fluorescence" he says, "The study results in supporting the age-old belief that strong or even very strong blue fluorescence can improve appearance rather than detract from it, especially in diamonds with faint yellow body color."
