Medium green to dark ...
5 - 6
Named in 1789 by Abraham Gottlieb Werner from an old German term for dark minerals with no ore value and from "blende", meaning to deceive in allusion to it occurring in ore deposits but not yielding any metal and in 1978 by the IMA for magnesio- indicating Mg2+ as a dominant cation.
