A thumbnail size specimen with a large 4mm pseudo-octahedral crystal perched nicely at the center of the sulfide matrix. As is typical of Scorodite, it displays the alexandrite effect in which the color changes from purple to blue depending on the light source.You will notice at the top of this crystal is an imperfection caused by an overgrowth of another mineral which is still attached. It is NOT damage.
