*You will need a true filtered Shortwave 254nm UV light in order to see the fluorescence shown in the pictures. A Longwave lamp will barely show fluorescence*
*Regular black lights, purple lights, or blue lights don't usually work for fluorescent minerals, so make sure you use the proper indicated UV light*
*Please keep in mind that the higher the UV light's wattage is, the brighter the fluorescent reaction will be*
This specimen was photographed using an Engenious Designs Shortwavw 254nm UV flashlight, and with a longwave Convoy C8 365nm UV flashlight. The pictures have not been retouched.
