Description:
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.
Summary of luminescence responses:
