Au Seeker Posted March 19, 2013 Share Posted March 19, 2013 There are many minerals that florescence yellow, and some florescence a different color depending on if the UV light is longwave or shortwave, here's a link to some of the florescence colors in a list. http://www.galleries.com/minerals/property/fluotabl.htm Quote Link to comment Share on other sites More sharing options...
