Yes it is a mineral. SiO2 in composition. Commonly it can be coloured by trace elements such as iron.
No! Diamonds are a pure form of carbon, while quartz is a silica-oxygen compound. According to Wikipedia quartz is the second most abundant mineral in the Earth's continental crust. It is a major component of sand.

Quartz is a silicate mineral. In fact, quartz is pure SiO2 (Silicon Dioxide). Most of the Earth's crust is made of silicate rock.
Quartzite is composed mostly of silica. It contains minerals like zircon, rutile, and magnetite, and the silica cements them together.

Quartz is a naturally occurring mineral and may be found in all three types of rock. Quartz in found in the ground. It is a common constituent of granite, sandstone, limestone, and many other igneous, sedimentary, and metamorphic rocks. It is the most abundant mineral in Earth, therefore, you can find quartz almost everywhere.
Quartz is always a mineral.
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
No quartz is a mineral.
