  Those diamonds that produce a visible reaction when exposed to ultraviolet radiation. In laboratory experiments with both trained gemmologists and individuals with no diamond experience (meant to represent the jewellery-buying public), no relationship was found between fluorescence and a diamond's overall appearance.
