Zoisit

Also known as Saualpite

Zoisite, first known as saualpite, after its type locality, is a calcium aluminum hydroxy sorosilicate belonging to the epidote group of minerals. Its chemical formula is Ca2Al3(SiO4)(Si2O7)O(OH).

Zoisit är ett mineral, som påminner om epidot och som är ett silikat av kalcium och aluminium. Den upptäcktes 1805 av baron Sigmund Zois von Edelstein, därav namnet. Inte förrän 1954 fann man stenar i ädelstenskvalitet av denna sten. I Tanzania hittade man en blå sten och varieteten kom senare att kallas tanzanit. Det finns även en röd varietet – thulit.
