What Does the Name Quartz Mean?

Quartz is one of the most abundant minerals on Earth. It is found in a wide variety of geological settings and in a diverse range of crystal habits. The name “quartz” is derived from the German word “quarz,” which, in turn, is derived from the Slavic word “kvarc.” The word “kvarc” is thought to mean “hard,” which is a reference to the mineral’s hardness.

Etymology of the Name Quartz

The name “quartz” was first used in the 16th century by the German mineralogist Georgius Agricola. Agricola used the name to refer to a hard, translucent mineral that was found in association with ores of silver and lead. In the 18th century, the French mineralogist Jean-Baptiste Romé de l’Isle used the name “quartz” to refer to a specific mineral species that was characterized by its hardness, its conchoidal fracture, and its hexagonal crystal habit.

Composition and Structure of Quartz

Quartz is composed of silicon dioxide (SiO2). It is a hard mineral with a Mohs hardness of 7. Quartz is also a piezoelectric material, which means that it can generate an electric charge when it is subjected to mechanical stress. Quartz is the most abundant mineral in the Earth’s crust. It is found in a wide variety of geological settings, including igneous, metamorphic, and sedimentary rocks. Quartz is also found in veins and pegmatites.

Crystal Habits of Quartz

Quartz can occur in a variety of crystal habits. The most common crystal habits are hexagonal prisms, dipyramids, and rhombohedra. Quartz crystals can be transparent, translucent, or opaque. They can also be colored by impurities. The most common colors of quartz are white, clear, pink, purple, and yellow.

Uses of Quartz

Quartz is used in a wide variety of applications. It is used as a gemstone, an abrasive, and a piezoelectric material. Quartz is also used in the production of glass, ceramics, and concrete.

Gemstone
