Erich Keck, a German collector of Hagendorf minerals, is the namesake for Keckite. Keckite is a rare weathering product of phosphates in granite pegmatites. It can be found in Germany, Portugal, and newer localities in the United States, Australia, and the Democratic Republic of the Congo.

Named for the old word given to red amorphous antimony trisulfide, kermes, which gets its origin from the Persian word qurmizq, which means “crimson.” Kermesite is an uncommon, but widespread mineral that can be found in localities in Germany, the Czech Republic, Slovakia, France, Italy, Russia, Bolivia, Australia, Zimbabwe, Mexico, Canada, and others. It occurs as an alteration of stibnite in antimony deposits.
