diallage
Sign in to saveDiallage is an inosilicate, meaning it is a chain silicate, and is a part of the pyroxene group. Diallage is a junction between augite and diopside, just like fassaite. It was named in 1801 by René Just Haüy. Its name derives from the Greek word diallaghé (meaning change, transform, difference), as its composition differs from that of the other minerals in the pyroxene group. It is a fairly common mineral, and is cheap.
