Saussurite

Saussurite is a translucent to opaque grayish to yellowish green, (often mottled) aggregate that's often used as a jade simulant for carvings. Containing zoisite, epidote and sodium-rich plagioclase feldspars, it was named after the Swiss naturalist Horace Bndict de Saussure, who originally believed it to be jade.
