Quartz is made up of silicon and oxygen atoms. It is the second most abundant mineral on Earth next to Feldspar. It forms in almost all mineral environments at all temperatures. It is present in igneous, sedimentary, and metamorphic rocks. Even the sand of beaches, rivers, and deserts contain significant amounts of Quartz.
Dig deeper into the properties and history of this universal stone.
The Physical Properties of Quartz
With a Mohs hardness rating of 7, Quartz is a highly durable mineral. It remains very stable even when exposed to extreme temperatures and harsh chemicals. Unlike other minerals that dissolve in weaker acids, Quartz – like other silicate minerals – is only soluble in hydrofluoric acid.
While it is durable, the mineral is also very brittle. It easily forms rounded or shell-like conchoidal fractures when subjected to pressure. This is why Quartz crystals naturally have marks or grooves on their surface. It also has a vitreous or glass-like luster.
Pure Quartz has a clear or white colour. However, the presence of mineral impurities can make the mineral purple, pink, green, yellow, orange, blue, or red. For instance, Amethyst (the most common variety of Quartz) can display a lilac to deep purple colour due to traces of iron in the stone.

The History of Quartz
It is believed that the name Quartz comes from the old German word querkluftertz meaning ˜cross-vein ore.' The word was first used in 1530 by Georgius Agricola, the father of mineralogy. Ancient Greeks and Romans referred to Quartz crystals as krustallos meaning ˜ice.' This stemmed from their belief that the mineral was ice that never melted because it was created by the gods themselves.
Quartz has been widely used since the ancient times. The Sumerians used it to create cylinder seals and ring seals. They may have also used it as a stamp for producing written impressions in clay. In ancient Egypt, Quartz was a primary material in making beads, amulets, impression seals, and various jewelry pieces.
In the modern world, the mineral is an indispensable component in creating electronic devices due to its ability to convert electrical energy into mechanical energy. Quartz crystals are used in creating radios, transistors, microphones, digital watches, computer chips, and electric guitars.
Quartz also finds its way into glassmaking. Quartz sand is used in producing fiberglass, container glass, flat plate glass, and specialty glass.

Earliest Greek, Roman, and Egyptian civilizations used Quartz crystals as amulets and talismans. Ancient Japanese culture believed that Quartz was made from the breath of a white dragon. They associated Quartz with perfection.
Aboriginal tribes in Australia and South America link Quartz crystal with creation myths, believing that the crystal guided the creation of all life forms in the universe.
Beginning in the middle ages, different forms of crystal Quartz like balls and skulls have been used in many rituals to predict the future.
