*You will need a longwave (LW 365nm) UV light in order to see the bright fluorescence shown in the pictures. (A shortwave SW 254nm light will show a very dull pink 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*
This specimen was photographed using a C8 longwave Convoy ultraviolet flashlight. The pictures have not been retouched.
*Please keep in mind that the higher the UV light's wattage is, the brighter the fluorescent reaction will be*
