Quartz is derived from the German word “quarz” which means hard. The Ancient Greeks described Quartz as icy cold as they thought it was a form of supercooled ice. Women of high standing would hold a clear Quartz sphere to cool themselves during hot weather. When it is in its purest form, Quartz is sometimes referred to as Rock Crystal.
In the Earth’s crust, Quartz is the most common mineral, and the second most abundant after Feldspar. It is made of Silicon Dioxide otherwise called Silica. This mineral is found in all of the different rock formations. It is weather and mechanical resistant. If it does erode, the smaller pieces are found in rivers, on beaches, and in the soil. The white sands of beaches are mostly composed of Quartz though there will minute amounts other minerals with it. There is a greater variety of names given to Quartz than any other mineral.
Some of the Quartz varieties include Chalcedony, Amethyst, Citrine, Rose Quartz, Smoky Quartz, Morganite, and Aventurine. The colors are due to chromophores which incorporate into the crystal structure of Quartz. Mixed, banded rocks which include Quartz are Agate, Carnelian, Sardonyx, and Jaspers. Milky Quartz also forms the inner lining of many geodes. The milky white color is caused by inclusions of gas, liquid, or both trapped during the formation of the crystal. While most people think of Quartz points with their six sides, it also forms twins (90 degree angle where they connect), scepters (where the top of the crystal is larger with a sort of stem that makes it look like a scepter), or phantom growths (where one crystal forms over another leaving a ghost like form inside).
Natural Quartz is rarely used as found except as a gemstone especially in jewelry and as carvings. Those used in electronics are cultured Quartz which are grown in a lab. To grow Quartz, a seed crystal is needed. A small piece of natural Quartz is selected as a starter on which the manufactured crystals will grow.
Quartz is piezoelectric which means that when pressure is applied to it, it creates a positive and negative charge. The charges are created on opposite ends so one end is positive and the other is negative. Quartz crystals vibrate at precise frequencies making it valuable for accurate timekeeping instruments, and for transmitting signals such as those used for television and radio. Some of the electronics containing Quartz in their circuitry include computer chips, cell phones, radio receivers and transmitters, ultrasound devices, televisions, clocks, watches, microphones, record players, GPS equipment, and electronic games. It is also used to make frequency control devices and electronic filters that remove defined electromagnetic frequencies. Optical grade Quartz crystals are used to make lenses, specialized microscopes, telescopes, scientific instruments, and electronic meters.
Since Quartz forms in molten magma, it is sometimes found with Gold, Silver, and Copper. Some Quartz, such as Libyan Glass Tektites, are formed due to meteorite strikes. Fulgurite is formed when lightning strikes Quartz in sand. All are formed under high heat conditions.
Sand, often composed of almost 100% Quartz, is used to make glass and fiberglass. Due to the hardness of Quartz it is also used as an abrasive in sandblasting, sanding grit, sawing, grinding media, and scouring cleaners. It is used in foundries since it is heat and chemical resistant. The melting temperature of Quartz is higher than most metals, so, it can be used for molds and bricks.
In the petroleum industry Quartz sand is forced into fractures to hold them open so that natural gas flows into the well bore and can be extracted. Quartz sand is used as a filler in some rubbers, plastics, paints, and putties. Sand is also found on volleyball courts, sandboxes, beaches, golf courses, and baseball fields. Fine Quartz grains are utilized in soaps, toothpastes, brake friction products, caulking compounds, and polishing compounds for metals, jewelry, and stones.
Some of the countries where Quartz is found include Australia, Brazil, Canada, France, Ireland, Mexico, Morocco, Poland, Namibia, Russia, Spain, The United States (Arkansas, Maine, and North Carolina), and Uruguay.
Metaphysical Properties: Clear Quartz is an amplifier. That means that whatever stones are near it (great for gridding) or whatever energies (good or bad) are present in the area where the crystal is placed will be amplified. Clear quartz can be programmed for whatever purpose you would like such as putting one in drinking water to improve your health or to use in a healing practice. As a programmable mineral, it stores information and may also help dissolve past karma. Since it is clear or white, it resonates with the crown chakra. It is a stone of light and brings spiritual awareness to the person working with it. The energies differ depending on the location in which the Quartz grew. Arkansas Quartz is very neutral and a wonderful choice for programming.
