Grenville, Quebec Province, Canada
    Marialite is a member of the Scapolite group of rock-forming silicate minerals, but in this special variety known as Wernerite, it fluoresces a brilliant yellow to orange-yellow, most vividly under longwave UV rays. It has been scientifically tested and shown to be the most brilliant of all longwave fluorescing minerals. This large 9¼ x 4¼ x 4-inch (23.5 x 10.8 x 10.2 cm) specimen is a great example of that brilliance, with the main faces extremely clean, bright, and about 90% Wernerite. It is also a superb shortwave specimen, under which rays it is shown to contain sizable spots of bright blue fluorescing Diopside, and the Wernerite is still extremely vivid under that light also. Presented here in an extremely attractive specimen, Grenville Wernerite is a classic fluorescing mineral that has been mostly unavailable for the last twenty years as the more recent Ladysmith Prospect finds have predominated on the market, although even that material is growing scarcer.

    Provenance: ex. Hugh Ronemus Collection
