In December 2013 Charles Mazel (NIGHTSEA) and Earl Verbeek (then at the Sterling Hill Mining Museum, now curator at the Franklin Mineral Museum) explored the extensive collection of the Franklin Mineral Museum (Franklin, New Jersey, USA) for instances of blue-light-stimulated fluorescence. When fluorescence occurred, the specimen was photographed under white light, shortwave ultraviolet light, longwave ultraviolet light, and blue light. Below are some striking examples.
To see a wider selection of what was discovered and to download a pdf of the paper they wrote about blue light mineral fluorescence go to the summary article of all posts to date.
