Here is a series of pictures of daylight fluorescence from two Locations of opal. One the recent find of Mexican Opal offered at Tucson and the Other a Namibian Opal. Both exhibit daylight fluorescence with the Mexican one being the obvious brighter of the two. The pictures go from Tungsten to Indirect sunlight to UV light.
