An iron-rich sodium silicate mineral, a variety of pyroxene that is black or dark green in color.
From Latin Aegyptus (Egypt) combined with -ite (mineral suffix), named because it was first identified in Egyptian specimens. The mineral was named with reference to Egypt, though similar minerals are found worldwide.
Aegyrite is basically the mineral world's version of a black diamond—dark, lustrous, and packed with iron. It forms in igneous rocks and was first scientifically described from Egyptian samples, which is why it got this classical name.
