Bustamite fluorescing under blue light

The geology community knows a lot about mineral fluorescence under excitation by various wavelengths of ultraviolet light but when it comes to excitation by light in the visible portion of the spectrum, such as blue, … not so much. In December 2013 Charles Mazel (NIGHTSEA) and Earl Verbeek (Sterling Hill Mining 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,  fluorescing under blue light, and fluorescing under either or both of shortwave and longwave ultraviolet light. The results were published in September 2014 – Mazel, C.H. and Verbeek, E.R. (2014), Fluorescence of minerals under blue light. The Picking Table (Journal of the Franklin-Ogdensburg Mineralogical Society), vol. 55, no. 2, p. 13-25.

Visit the blue light mineral fluorescence summary article for links to pages with images of a variety of mineral specimens, and to download a copy of the issue of The Picking Table with the article.
