Description
Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of SiO₄ silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂. Quartz is the second most abundant mineral in Earth’s continental crust, behind feldspar.
Prasiolite (also known as green quartz, green amethyst or vermarine) is a green variety of quartz.
Since 1950, almost all natural prasiolite has come from a small Brazilian mine, but it has also been mined in the Lower Silesia region of Poland. Naturally occurring prasiolite has also been found in the Thunder Bay area of Canada. As of February 2019, the only commercial mine producing prasiolite is in Brazil.
Most prasiolite sold is used in jewelry settings, where it can substitute for far more expensive precious gemstones.
