I enjoy seeing rocks light up under Short Wave Ultra Violet light, so do millions of other people in the world. It is exciting to see brilliant colors coming from, what commonly is, a not very visually stunning rock. While large exotic crystals can fluoresce, many times it is something drab and visually unappealing that shows brilliant reaction to \u201cblack light\u201d. As the field trip leader for an active group of rock hounds, my monthly trip for February of 2017 was to the area known for brightly fluorescent rocks in the Shadow Mountains, just West of highway 395, in the high desert of Southern California.
