Quartz is not just a beautiful mineral—it is one of the most abundant and versatile substances found on Earth. From high-end watches to ancient spiritual practices, quartz has played a significant role in human history and technological development. This crystal’s durability, unique optical properties, and metaphysical importance have made it a subject of fascination for geologists, engineers, and spiritualists alike.
In this article, we explore what quartz is, its different types, physical and metaphysical properties, industrial applications, and its spiritual symbolism in cultures around the world.
What Is Quartz?
Quartz is a silicate mineral composed primarily of silicon dioxide (SiO₂). It forms in igneous, metamorphic, and sedimentary rocks and is characterized by a hexagonal crystal system. Quartz can appear transparent, translucent, or opaque, and it comes in a variety of colors depending on the trace minerals it contains.
Key Facts About Qua-rtz:
Chemical formula: SiO₂
Hardness: 7 on the Mohs scale
Crystal system: Hexagonal
Luster: Vitreous (glassy)
Transparency: Transparent to opaque
Origin and Formation of Quartz
Qua-rtz forms when silicon and oxygen atoms come together and cool under specific pressure and temperature conditions. It is typically found in igneous rocks like granite, metamorphic rocks such as schist, and sedimentary rocks like sandstone.
Qua-rtz can crystallize in:
