Belgian smithsonite

One of Belgium's lesser known fluorescent minerals is smithsonite. It fluoresces weakly in SW UV but much stronger in the powerbeam of the Convoy S2+. The red fluorescence is activated by some lanthanide series elements. There's also a blue component caused by manganese and some humic acids. Contrary to the Mexican smithsonite from the Potosi mine, the Belgian counterpart is as good as lead-free. I placed a comparative spectrum on the MKA 's fluorescent minerals site. Go there to see it:
