Quartz is a mineral composed of silica (SiO2).
After feldspar it is the most common mineral found in igneous, metamorphic and sedimentary rocks.
It is noted for its hardness and resistance to weathering on the earth’s surface.
Two types of quartz are distinguished: α-quartz and β-quartz.
Amethyst, citrine and milky quartz are some of the many varieties of quartz known in gemology.
