Quartzite stone, from which ancient hunters and warriors made arrowheads, is a rock that, thanks to its rich color palette and high strength, is valued by people no less than ruby or diamond. The stone is formed by fusing sandstone containing quartz with spar, mica and other igneous minerals. At high temperatures under pressure, the crystals turn into massive layers.
Story
Quartzite is one of the oldest materials used by people. The knives, scrapers, and arrowheads that modern archaeologists unearth are more than a thousand years old.
Later it became the basis of buildings, monuments, and roads.
The stone was equally revered by secular authorities and church hierarchs. The sarcophagus of Napoleon and the tomb of Russian Emperor Alexander II are made of quartzite. It is present in the design of the Lenin Mausoleum and the decor of the Church of the Savior on Spilled Blood in Moscow.
Magnetite thin-layered fine-grained jespellite quartzite (Annovsky quarry, Krivbass) in the museum of mining equipment of SevGOK.
Legends about the gem
According to ancient legends, dwarfs used to walk the earth and were involved in the construction of large stone buildings. An example is Stonehenge, in the rows of which there are quartzite structures. The Icelanders have a popular myth that tiny people lived underground and turned to stone when exposed to sunlight.
It is believed that the sarcophagus of Tutankhamun, the ancient Egyptian pharaoh, is made from the yellow mineral. Many people know about the curse that came into force after the opening of the tomb, which took people’s lives. The sarcophagus was carved with an image of a goddess with her hand raised. There is an opinion that this woman’s gesture is a warning, urging her to come to her senses and go back.
What is quartzite
Quartzite is a mountainous igneous or sedimentary rock, the result of the fusion of quartz sand with other minerals.
The color scheme, wear resistance, granular texture, and slight roughness make it similar to marble. After polishing, it is impossible to visually distinguish these stones.
Natural quartzite, unlike marble or granite, does not accumulate radiation.
Composition of quartzite. Minerals
The mineral composition of quartzite is predominantly quartz (quartz content in the rock reaches 88-98%), containing iron hydroxides (2-3%), silicon and chalcedony (4-5%). The stone also contains impurities of mica, talc, feldspar and other minerals. Quartzite is named according to its mineral composition (for example, kyanite, magnetite), and the proportion of the word-forming mineral must be at least 5%.
Separately, secondary quartzites are distinguished with the inclusion of sericite, alunite, corundum, topaz and other minerals. These are metasomatic rocks in which the primary composition has changed significantly as a result of reactions between minerals and solutions through which the rock is deposited.
Colors and varieties
One of the advantages of the mineral quartzite is its rich palette of shades.
Most common colors:
- Gray shimmers with silver.
- White - contains inclusions of gray or black spots, stripes on a white background.
- The black shines thanks to mica inclusions.
- The yellow stone is always light, with saffron and orange inclusions. Rarely seen.
- Crimson quartzite combines pink, brown, and red specimens.
- Lumen. Recognized by the smooth flow of gray, white, blue, greenish shades. Expensive variety.
The simplest is ferruginous quartzite. Metallurgists take it away.
Varieties of quartzite with photos
The material used to clad buildings was considered a ritual stone for centuries and was used in the construction of tombs and sarcophagi where kings and emperors rest. Rock layers have different colors, unequal hardness and are divided into groups.
The ferruginous variety contains a layer in the form of wide, thin, medium strips consisting of metal oxide. Most stones from this group have a brown or reddish tint; the strength value varies depending on the mineral present in the rock.
The second type includes white-colored quartzite and light-colored stones. In yellow crystals that are heterogeneous in structure, gray, orange, and dark inclusions are found. The milky mineral has no inclusions, and its properties such as strength and formal appearance allow the rock to be used for decoration.
The third group is represented by pink, crimson, scarlet minerals; nuggets of such shades are rare and have a high cost, red quartzite is especially valued.
Gray stones are found everywhere, attracting attention with their bluish surface, shining in the sun like silver.
By the way! Mica inclusions give the nugget shine and are painted black.
Physico-chemical characteristics
According to the chemical classification, quartzite is silicon oxide. The main component of the formula and composition of the stone is quartz (70%+). It is supplemented by iron, aluminum, calcium.
Physical characteristics:
- compressive strength 100-450 MPa.
- volumetric mass, average: 2.6 g/cm³, (pore volume included).
- density, average: 2.68 g/cm³ (pore volume excluded).
| Rock type | Metamorphic rock |
| Color | White, light grey, red, blue, yellow, green, etc. |
| Texture 2 | unclearly laminated flattened banded massive laminated spotted |
| Structure 2 | psammitic granoblastic microgranoblastic porphyroblastic microporphyroblastic fine-grained medium-grained |
| origin of name | by composition |
It is harder than quartz and granite. Resistant to fire, frost, aggressive substances, temperature changes, and abrasion.
Gem Features
The main part of the rock is quartz (about 70%). Additionally, it contains some metals: iron, aluminum or calcium. This all explains the natural hardness, comparable to alexandrites and diamonds. Therefore, stones are difficult to process, but easy to split along the line of veins.
Distinctiveness of natural substance:
- structure represented by small grains;
- wear resistance, fire resistance, frost resistance;
- the appearance of a reflection of a different color in bright light;
- sparkling in some specimens due to shiny inclusions;
- durability, resistance to high humidity;
- lack of reaction to alkalis and acids;
- inability to accumulate radiation particles.
Resistance to moisture and temperature changes, inability to absorb water determine the use of quartzite. Durable nugget has long been used in the construction of baths and saunas. The marble-like mineral is used to line the walls of buildings, lay out mosaic floors, and decorate sidewalks and flower beds.
Where is it used?
Physical and aesthetic characteristics determined the areas of application of the stone. It is difficult to cut and process. The only thing that is easy is polishing until it is perfectly smooth. After it, quartzite looks like marble.
Construction
Even in harsh conditions (unfavorable climate, intensive use), the stone does not deform for 260-320 years.
Buildings are decorated with quartzite plates, and the rock is used in road construction.
Crumbs are added to thermal insulation materials.
Design
Quartzite plate is used for interior and exterior wall cladding, countertops, and mantelpieces. The marbled rock is used to lay floors, fireplaces, and grand staircases. Their service life is tens of years.
This is the favorite material of landscape designers.
Baths, saunas, steam rooms
The mineral is resistant to temperature, penetration of fungus, moisture, and destroys bacteria. It is natural that quartzite for a bathhouse is recognized as the ideal solution:
- To obtain healing steam, a stone is laid out on the floor in front of the stove or in a depression in it.
- The wall opposite the stove, when heated, releases healing substances.
Raspberry quartzite for a bathhouse
For these purposes, choose white quartzite. Raspberry is considered a premium finish.
Jewelry, decorative and applied arts
Jewelry companies do not work with stones. Handmade masters make large items - beads, bracelets, pendants.
They make balls, massage sticks, and animal figures.
Other industries
Quartzite sand or crumbs are used to fill filters for water purification.
It is bought up for purification of tap water by owners of swimming pools and aquariums.
Water gets rid of harmful impurities, bacteria die in it.
Quartzite mining
The main deposits of the mineral are located in Russia (Karelia), Ukraine (Krivoy Rog), and the USA (Lake Superior). Like any other natural stone, quartzite is mined using a quarry method. There are three ways to mine stone:
- Explosive. Holes 10-20 m deep are drilled into the solid layer of rock, and explosives and detonators are placed in them. Several dozen wells are used to undermine the formation. This is the cheapest method, leaving a large amount of waste, and is relevant when crushed stone is needed for construction work.
- Air cushion method. Holes are drilled in the mining area and filled with air under pressure. As a result, a fault is formed, breaking off the block from the main massif. The method does not lead to the formation of microcracks and is generally more gentle compared to explosive.
- Stone-cutting. Blocks of quartzite are cut out of the formation using rope stone-cutting machines. For this purpose, special diamond-coated cables are used. The resulting blocks are removed from the mining area by heavy cranes.
After extraction, the resulting material is sorted, crushed or sawed into slabs in a specialized workshop.
How to wear and care
The stone does not need special care. You can minimally care for it:
- Store in a common box.
- Remove dirt with warm water and soap.
- Light-colored pebbles (especially pink and yellow) should be protected from direct sun to prevent them from fading.
Quartzite products are worn at home, at work, for a walk, or at a party. But not for status events.
There is an option for every age: pink quartzite for young girls, crimson stone for more mature ladies.
Aesthetes and people who want to stand out choose red quartzite.
How to distinguish a fake from a real stone
Quartzite rocks are found in abundance in the earth's crust. Therefore, there is no reason for suppliers to counterfeit the mineral. In addition, these are inexpensive stones, and there will be no special profit from counterfeiting them.
Synthetic analogues are also not created, but it is possible to bring this idea to life. It is enough to combine quartz sand with mica, spar, and place the mixture under pressure and high temperature.
There are practically no counterfeits, but the nugget is often confused with quartz, the main substance. The difference between minerals is significant. Components of quartz: oxygen and silica. While the material derived from it is the result of sandstone metamorphism. The difference between quartz and quartzite lies in the structure. The first is a crystal, the second is a metamorphic rock.
Magic properties
The magical influence of the stone has been known to sorcerers for centuries. They made talismans for warriors.
Today, the magical properties of quartzite are used for more practical purposes:
- it gives confidence and increases self-esteem;
- protects the small, weak, and elderly from physical violence;
- helps you make the right decisions;
- protects against dangers outside the home.
The magic will manifest itself more strongly if you wear a stone amulet or place a figurine on the table.
Use of quartzite
- Road and capital construction. Crushed stone from low-grade quartzite is used to form concrete mixtures and as a cushion in the construction of foundations, supports, and laying asphalt.
- Metallurgy. The mineral is used as a flux that lowers the melting point of metals. Crushed crushed stone is used as an additive, with the help of which the slag is separated from the metal melt.
- Production of refractory materials. Crystalline quartzite is used in the manufacture of silica refractory bricks for laying heating furnaces. Dinas quartzite contains 96-99% SiO² with a minimum amount of alumina and alkalis.
- Bath stone. Rolled quartzite, especially crimson, is used to organize heaters in baths. Large fractions of stone are placed in the lower part of the heater, and small fractions are placed in the upper part.
- Interior design. Quartzite is widely used for finishing floors, window sills, sinks, and stairs.
- Facing. Due to its good frost resistance and resistance to aggressive environments, this mineral is suitable for exterior decoration of buildings, arrangement of gazebos and fountains. It is often used to design garden landscapes, recreation areas, and house terraces.
Storage and care
Quartzite is not picky to care for. Basic rules that should be followed if there is a product made from this stone in the house:
- Protect from sunlight so that the color does not lose its attractiveness and freshness.
- Do not subject quartzite to sharp impacts to avoid chips and cracks. Due to its increased strength, the stone is not afraid of scratches.
- Wash quartzite products with soapy water and a soft brush. Use special cleaning and polishing products to clean countertops, shelves, bathtubs and washbasins. It is not recommended to use aggressive chemicals and abrasives.
Therapeutic effect
Lithotherapists attribute to quartzite the property of identifying ailments. If you carry the stone with you for several days, it will indicate a health problem - the organ that is affected by the disease will begin to ache.
Among the healing properties of quartzite, it is worth highlighting its beneficial effect on:
- thyroid gland;
- immune system;
- respiratory system.
To boost your immunity, you should drink water infused with quartzite. This is especially useful for older people.
Quartzite stone. Properties of quartzite. Description of quartzite
Quartzite is a rock. In other words, the stone is composed of several minerals. The main one is quartz. Hence the name of the breed. Corundum, topazes, pyrophyllite, sericite, talc, and feldspar are mixed with quartz in small quantities.
The mixture is formed by recrystallization of sandstones. Their metamorphosis occurs under the influence of pressure or temperature. By the way, the concept of “metamorphic rocks,” to which quartzite is included, comes precisely from the word “metamorphosis.”
Physical and chemical properties
The sandstones from which quartzite is obtained consist of large fragments of sedimentary origin, held together by natural cement. During recrystallization, some impressive sandstone fragments are preserved.
Therefore, quartzites often have an uneven structure. Large crystals of quartz and mica are clearly visible in them. The bonding of particles of different sizes makes the stone strong.
The strength characteristic is also related to the composition of the rock, because its main component, quartz, has a hardness rating of 7 on the Mohs scale. Topazes, also included in quartzites, occupy the 8th line on the scale.
Corundum mixed into the rock is only one point inferior to the hardness record holders diamonds. The latter score is 10 points. So, in total, the hardness of quartzites is approximately 8 points.
In addition to increased strength, quartzite is temperature resistant. The stone is not affected by its negative values. Fire resistance is also impressive. The rock begins to change only at a temperature of 1770 degrees Celsius.
This resistance to heat makes the material an excellent raw material for the construction of steam rooms. Quartzite for a bath makes it both safe and durable. The service life of the rock during active exploitation is 2-3 centuries.
Quartzite doesn’t care about high humidity. The stone is not affected by chemical reagents. The rock does not react with either acids or alkalis. However, quartzite stone is in no hurry to yield to humans.
Due to its increased hardness, the material is difficult to process. This increases the cost of products made from the breed. People usually want to buy quartzite For example, Napoleon's sarcophagus was made from this stone.
Color and color of quartzite
Like quartz, the rock containing it comes in a wide range of colors. Standard set - white, yellow, gray, cherry. Less common are purple, crimson, blue, green and black stones. These paints are given by rare mineral impurities.
Crimson quartzite lines the presidential courtyard in the Kremlin. The rock for the paving stones was obtained from Karelia. The crimson shades of the stone are valued in China. In the Celestial Empire, thousands of monumental buildings are made of purple quartzite.
The crimson breed is considered the most valuable. They ask for about 10,000 rubles per ton. The stone is dense, heavy, a ton of quartzite - one impressive cobblestone.
The most budget option is the most common white breed. From it, for example, the Church of the Savior on Spilled Blood was built. for milky quartzite is about 5,000 rubles per ton.
Quartzite is valued not only for its color palette, but also for its shine. Interspersed with mica and quartz give the stone a radiant appearance. The breed sparkles. Considering that quartzite can be easily polished, the craftsmen manage to “beat” this property of the stone 100%.
Quartzite deposits
The stone is common. Among metamorphic rocks it occurs in large, extended layers. Such deposits are found in Africa, America, Eastern Europe and Russia. In the domestic open spaces, 30 deposits have been taken into account. Their main concentration is in the Urals.
Talismans and amulets made of quartzite
Quartzite amulets are loved by doctors and those who are concerned about their health. It is believed that the breed helps to recognize hidden illnesses. When you constantly wear a quartzite talisman, the affected organ or system of the body begins to hurt. Outside the influence of the stone, the disease can be asymptomatic.
In Europe, quartzite was nicknamed the stone of heroes. Talismans made of quartzite are worn by military personnel, because esotericists claim that quartzite imparts courage, the ability to be responsible for one’s actions, and develops willpower. Alchemists of past eras noticed that the breed turns an ordinary young man into a knight.
Quartzite is also taken on long journeys. The stone, magicians note, wards off adversity from travelers and helps to find a way out of problematic situations. In addition, quartzite protects against the evil eye. For this reason, it is often worn as a talisman by mothers and teenagers.
There are restrictions on zodiac signs. Quartzite is not recommended for people of the fire element. These are brave, persistent, persistent individuals. Quartzite also imparts these same qualities. As a result, there is an excess that negatively affects fate.
Applications of quartzite
In addition to mascots, the breed has found wide application in the industrial sphere. Quartzite is used in road surfaces. In them, the material serves as a ballast layer.
The breed found the same application in railway tracks. The stone is used in filters for water purification. The breed is used in both household and industrial filters.
The beauty and durability of quartzite is the reason for its use in architecture and decoration. Monuments are made from the rock, buildings are erected, furniture, vases, paintings, and paving slabs are produced. The bottom of the pools is lined with quartzite.
Stone strengthens the foundations of buildings. Yellow, gray or white quartzite is easy to maintain. This property, combined with aesthetic characteristics, captivates builders of airports, palaces, kindergartens, and park complexes.
Magical and healing properties
Considering the magical properties of quartzite, being in buildings built from it is not only pleasant, but also useful. Since the breed is strong and durable, it is believed that it can make a person resilient, strong, and healthy.
Quartzite bestows willpower and does not like irresponsibility. In the presence of the stone, you will have to bring things to an end. This does not apply to bad beginnings. So, for example, quartzite protects women and their children from the excesses of heads of families and other men. If they decide to hurt the weak, they will not be able to complete what they started. The presence of quartzite blocks aggression.
Features of use in the bath
For a bathhouse, crimson quartzite millet is a godsend. It is rightly called the royal bath stone; it is believed that in addition to steam and warmth in the room, it has a beneficial effect on the body and well-being. In a bathhouse where a mineral is used in a stove, a person feels light and comfortable, and gets the opportunity to be imbued with the strength and energy of a natural mineral.
The main function of a stone in a bathhouse is the accumulation and subsequent release of heat. This ability of the breed allows you to maintain a comfortable temperature in the steam room and the room as a whole. Even under the influence of high temperature, the stone does not crack or break, maintaining its basic properties.
For masonry, minerals of different sizes are used, with an average diameter of 5 to 25 cm. They begin by laying large stones, gradually reducing the diameter. The top of the oven is laid out with the smallest samples. It is believed that masonry made from cleaned stones will be the most durable.
In addition, an important point is the sorting of minerals. It is necessary to select samples without cracks or chips. Damaged rocks will disrupt the properties of the steam room and negatively affect the air circulation in the room.
You need to select stones for a bath carefully and manually, rejecting damaged ones for several reasons.
- The first sign is appearance. It is necessary to inspect the sample for the presence of chips, veins, and cracks. The ideal mineral is one with a uniform surface.
- The second sign is by sound. It is enough to tap the stone with a hammer to determine its quality. A suitable mineral “sounds” thin and loud. A dull sound indicates the presence of hidden flaws and, as a consequence, fragility.
- A simple way to reject low-quality stones is a fire test. Minerals are placed in the fire. Samples that pass the test can be considered suitable for the oven.
In conclusion, it remains to add that all types of bathhouses crumble over time and become unusable. This is a normal phenomenon for minerals and is difficult to avoid. This must be taken into account when laying the stove with crimson quartzite. From time to time you should sort through the stones to remove crumbs. In this way, it will be possible to prevent a decrease in smoke draft and deterioration in the operation of the furnace as a whole. The advantages of crimson quartzite over analogues for bathhouses is that it does not need to be sorted out as often.

Jewelry and amulets
The stone is capable of endowing the owner with warlike traits: perseverance, courage and unbending will. Quartzites are popular as talismans for the military.
It is believed that this group of stones encourages the owner to take responsibility for his actions; he strives to correct the injustice committed towards someone: the mineral ennobles the soul and gives strength to fight. An irreplaceable talisman for a lawyer.
Crafts and jewelry made from quartzite are valued by healers, believing that it will allow them to recognize hidden human diseases and provide an opportunity to defeat the disease at its very beginning, avoiding serious consequences.
Sailors and travelers love this mineral, hoping for the magical properties of the stone to protect them in a storm and at a crossroads, and to suggest the right decision in a moment of danger.
Quartzite is also suitable for women who need protection. He will protect the young woman from violence and give her an easy birth. It will not allow an older lady to lose her mind and will maintain her physical health.
Violet-lilac quartzite will keep you from indefatigable alcohol consumption.
A mineral given as a gift by someone, rather than purchased with one’s own money, triples its magical properties. But the power of the stone weakens if it falls into the hands of a double-minded, deceitful person. Quartzite can even split, bringing a whole stream of misfortune and suffering to the dishonest owner.
To feel the full power of the magical mineral, you should throw off the shackles of the frames from the stone. It must “breathe”, only then will its energy be able to freely contact the owner’s energy field. Therefore, the best option is an amulet or beads cut from a single piece, adjacent directly to the body.
Appearance
Since quartzite stone mainly consists of grains of the monomineral rock crystal - quartz - it is not surprising that the warm surface of the stone seems to be covered with a frosty silvery haze, which is created by its light refractions.
Because of its strength, quartzite is difficult to process, but products made from it, polished to a smooth shine, are not inferior in beauty to majestic marble.

Popular types of natural quartz stones for sauna
Today, the most common natural quartzite is available in two shades. Minerals are great for a variety of purposes, but are most often used to create a gentle, healing steam. .
Quartzites of white and pink shades can most often be found in heater stoves
White quartz
Light quartzite is best suited for a bathhouse. Among its advantages we can highlight the excellent:
- Strength.
- Heat resistance.
- Heat capacity.
The main distinguishing feature of the quartzite rock is its ability to release oxygen. Thanks to this, the blood is saturated with O2 and brain function is stimulated, and a person’s well-being improves.
When heated, the crystals release ozone, which rejuvenates and cleanses the skin, making it rested and healthy.
