This is a high resolution SEM-picture of destinezite from Richelle, near Visé, Liège Province, Belgium. The nodules found in Belgium are dull, beige colored, looking rather amorphous and pulverulent. But at very high magnification (in this picture 23800 X) well formed six-sided plates can be observed. Those platelets are about 1.5 X 3 µm "tall" 0.0015 X 0.003 mm). Note that this mineral is not hexagonal, but triclinic !
