What is Quartz?
Quartz is a chemical compound consisting of one part silicon and two parts oxygen and iis known as silicon dioxide (SiO2). It is the most abundant mineral found at Earth's surface. Its unique properties make it one of the most useful natural substances.
Quartz with red inclusions of iron oxide is more rarely found, and is often sold under the name strawberry quartz or "red fire" quartz. Some specimens have very fine inclusions that are only visible under magnification, lending the quartz a more or less uniformly strawberry colour. Others have clearly visible inclusions and may appear as clear quartz with reddish needles, flakes or spangles.
