Fluorescent Wernerite (Scapolite)



This mineral produces a strong yellow color when exposed to longwave ultraviolet (UV) light. It is called wernerite a variation of scapolite. The label for this mineral lists it as being from Otter Bay, Canada. I could not find any reference to this locality but did find that scapolite was found at Otter Lake, Qu├ębec, Canada.


Specimen is approximately 4 cm x 4 cm x 3 cm in size.


H.C. Dake 1953 book The Uranium and Fluorescent Minerals describes wernerite 'is generally regarded as one of the strongest of all long wave mineral "fluorescents."'.


According to mindat.org this mineral was named in 1800 from Abraham Gottlob Werner (1749-1817) who was a German mineralogy professor.
