Fundamentally it is a mineral, however it is possible to get a rock type made entirely of quartz, in which case the rock would be called a Quartzite.
Quartz is an example of a mineral, not a rock. It is the second most abundant mineral in the Earth's crust and is commonly found in sedimentary, metamorphic, and igneous rocks.
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.
Quartzite rock is primarily made up of the mineral quartz, which is a hard, abundant mineral composed of silicon and oxygen atoms. Quartzite can also contain other minerals such as feldspar, mica, and iron oxides, but quartz is the dominant mineral in this type of rock.

Quartz is a mineral primarily made up of silicon and oxygen. It is the second most abundant mineral in the Earth's continental crust and is commonly found in igneous, metamorphic, and sedimentary rocks.
Quartz is a mineral consisting of silicon dioxide (SiO2) and is not classified as a rock on its own. It is one of the most abundant minerals in the Earth's crust and can be found in various types of rocks, including granite, sandstone, and quartzite.
