Does Diamond Fluorescence Affect Value?
When shopping for a diamond, you probably know you should closely examine the stone’s 4C’s, meaning the cut, carat, color, and clarity - but what about its fluorescence? Many people are unfamiliar with this term which further describes the diamond outside of its clearness, color, size, and shape.
Diamond fluorescence refers to the glow produced by a diamond when underneath an ultraviolet light, or a blacklight. It’s estimated that about 30% of diamonds have some degree of fluorescence, so chances are you'll run into some of these stones while shopping for a diamond.
