One of the most widely used and common building materials are building stones that have been widely used from the past to the present. In the past, people used building stones to build emirates and cities. As one of the reputable international suppliers and exporters of building stones, we are ready to provide you with the necessary advice in this field and the use of the network. We offer you the best product from completely dedicated manufacturers and miners.Today, with the growth of science and technology, in addition to ease of extraction, the use of stone in the construction industry and building facades has greatly increased.Among all building materials, building stones have very high capabilities that can not be compared with other materials. Among the capabilities of stone can be very high strength, optimal polishing, high resistance to abrasion and impact, cutting and polishing, washability and color stability, resistance to heat and moisture, suitable tensile and flexural strength, impermeability, changes Climate, hardness and resistance to high pressure, resistance to acidic and alkaline substances and so on.

Persian stone

Iran ranks fourth in the world ranking of building and decorative stones, but ranks first in the world in terms of color quality and variety of stones. Iran’s share in the global natural stone export market averages up to 15% per year. Iranian factories also continue to export ready-made products from natural soft stone. Many experts consider Iranian stone to be one of the highest quality stones in the world. Most of Iran’s exports of ready-made stone products are related to tiles, slabs and travertine. Of course, Onyx should not be forgotten because it has retained its special customers from the past. Onyx stone is widely used, including tile molds, slabs and products for interior and exterior decoration of buildings and decorations, fireplaces and bathtubs. The total volume of Iran’s export shipments is 10 million square meters per year.

Iran produces, processes and exports marble, granite, travertine and marble, which are among the highest quality and most diverse natural stones in the world.

The most important building stone mines in Iran

It is the center of production and processing of Iranian stone in Isfahan province, which has the most stone and the most variety.The most important building stones of Iran are 44% marble, 25% porcelain, 20% granite, 10% travertine and about 2% marble.

Provinces producing crude stone (based on production) include the following provinces:

Fars, Isfahan, Markazi, Kerman, Lorestan, South Khorasan, Tehran, Yazd, Qom, East Azerbaijan, West Azerbaijan, Zanjan, Qazvin and Hamedan

The most common building stones in Iran include the following stones:

Granite, gabbro, sandstone (including: calcareous sandstone, silica sandstone, iron oxide sandstone, dolomitic sandstone) diorite, quartzite, marble, marble, travertine.A variety of building stones are used for facades, interior wall coverings, road infrastructure, walls and foundations, streets and sidewalks and various decorations. The use of each is different according to the materials made of stone and each has its own characteristics according to the characteristics of the stone.

Types of building stones


Granite is one of the most widely used types of stone in buildings, used on floors, walls and stairs. This type of stone has a texture with medium to large grains and the minerals in it are found in different colors from pink to bold gray and even black. Granite is one of the heaviest stones and has high strength and resistance and can be found in cities such as Hamedan, Boroujerd, Mashhad, Natanz, Gilan, Nehbandan, Yazd, Zanjan, Khorramdare and Toos.

 It is noteworthy that this stone can not only play an important role in strengthening the building, but also due to the variety of colors, can be used as a factor to decorate various buildings. In addition to the widespread use of granite in the country, this product is also one of the important stones for export from Iran.

Advantages of granite:

  • High strength and durability

  • Resistant to water and chemicals

  • Beauty and uniform surface: Unlike travertine, granite has a completely uniform surface

Granite colors:

In general, granite can be divided into the following four categories in terms of color:

Disadvantages of granite:

  • Relatively high price

  • Radiation harmful to the human body

  • High weight and low adhesion

  • Lack of sound and heat insulation

  • Rust in some packages

 مرمریت (marbel)

This stone is a type of metamorphic limestone and due to less porosity than travertine stones has a relative strength and weight and has less strength and weight than granite stones.Due to the existence of many mines of this stone, marble can be provided with reasonable prices and great variety. In most marbles, there are many lines that can not be touched and felt in any way, and it has made it more beautiful. Marble is one of the most similar stones to travertine and is the way to distinguish it for non-specialists from behind the stone (behind the side).The total number of marble mines in the country is about 652 mines, most of which are located in Isfahan province with a share of about 163 mines. Fars province with 76, Khorasan Razavi with 67 and Kurdistan with 51 mines are in the next ranks.According to the distribution map of mines, marble poles can be considered as the center, south, northeast and west of Iran. Fars province is ranked first in the country in terms of marble quality and most of the marbles in this province are purchased exclusively by foreign traders and transported abroad for processing.

Advantages of marble:

  • Beauty and variety of colors and designs

  • The surface is almost uniform and more uniform than travertine

  • The price is right

  • Resistant to alkaline conditions

Disadvantages of marble:

  • Constant exposure to moisture causes corrosion and erosion on the surface

  • In some types of stone, if the corrugated type is used as a floor, the surface of the stone will not .have good resistance to scratches and scratches

  • Possibility of freezing and breaking the outer layers in most samples of this stone

Marble quality:

One of the best-selling stones is marble. Most limestones have little resistance to weather conditions, and marble is no exception to this rule in most specimens, but if the amount of veins is less, marble has the highest resistance and therefore buys the stone. With fewer lines, it can be the most appropriate choice.

Types of marble:

According to the samples extracted from marble and their mines in the country, as well as the variety in structure, design and color of this stone, they can be grouped in the following cases:


Travertine is one of the sedimentary rocks consisting of hot spring sediments that has a very beautiful appearance and its use is the facade of residential and office buildings and is always considered as one of the well-known and very popular stones around the world.Currently, there are 52 active travertine mines in Iran and 24 active mines under the supervision of the Association of Stone Mine Owners. Mahallat, one of the functions of Markazi province, has the largest travertine reserves in the Middle East, and this city, as a center of stone production, produces 50% of the total travertine mine in Iran.One of the best types of this stone is Abbasabad travertine because it is relatively abundant in terms of the existence of the mine and its size and can be seen in different colors and designs. is  The greatest variety of this stone is semi-transparent and its transparent and shiny species are very rare.

Appearance and color of travertine:

 These stones are found in nature in white, chocolate, light and dark cream, yellow, red and lemon colors and are produced in brown and black colors in the stone industry. Travertine is composed of many cavities and porosities and acts as a suitable insulator against sound and heat. This stone has many demands for the exterior of the building and one of the main reasons is the very high resistance and strength of this stone against heat, wind and heavy rains.

Available travertine mines:

 Travertine mines in Iran include: Abbasabad, Hajiabad, Azarshahr, Darreh Bukhari, Abyaneh, Kashan, Esk, Bukan, Torshab, Takab, Tafresh, Miandoab, Venogog, Hamedan and Zanjan.

Advantages of travertine:

  • The most important and one of the main advantages of buying travertine is its availability and very reasonable price.

  • The outer surface of this stone is very resistant to extreme cold and does not cause cracks, corrosion and falls.

  • Travertine stone is a very good choice for covering the interior of large and small pools and relatively warm places due to maintaining cold and coolness in its surface layer.

  • Numerous pores and cavities on the surface of this stone make it very suitable for covering floors and corridors and reduce the possibility of slipping and slipping to almost zero.

  • It is very resistant to abrasion, discoloration, paleness and damage and provides a lot of strength.

  • It has a very beautiful appearance.

Disadvantages of travertine:

  • Low resistance to acidic conditions

  • The possibility of crushing and breaking in severe cold is another major problem of travertine (although this problem has been largely resolved with resin.)

  • Another notable disadvantage of this stone is the non-uniformity and spectrality of the colors inside the travertine stone.


Marble is composed of metamorphic limestone. This mineral has large and distinct crystals or in the form of granular masses, the most valuable feature of which is its high purity and transparency (unlike marble, which does not have transparency) and therefore the price of this stone is higher than other stones. It has a very high quality in terms of beauty, gloss and transparency.The best and most expensive building and decorative stone in the world is marble, which is available in natural and various colors and designs in Iranian mines. Due to its unique beauty and high quality, marble is usually cut in the form of large one-piece stones (slabs) and most of it is exported to other countries.

Marble Highlights:

Solubility, strength, hardness, firmness, color, texture, porosity.

The hardness of marble is 3 to 4, but it should be noted that marble made of quartz has a higher hardness than calcite marble.


 Diorite is an inner igneous rock and is generally gray to dark gray in color and can even be black or bluish, gray and greenish gray. Diorite stone has high durability and strength and therefore is often used as a base material in the construction of roads and buildings.


Quartzite is a metamorphic and very hard rock. Quartzite is generally available in burnt brown, white to gray, pink to red, yellow, and orange due to the presence of other impurities in the rock. Quartzite is a type of building stone that looks like marble but has a higher strength and is similar to granite but has a higher hardness. The price of this stone is lower than other stones.Quartzite rock is more resistant to environmental factors such as cold, heat, acidic materials and abrasion than other rocks and does not disappear over time. Quartzite is often confused with granite, but it should be noted that this stone is much harder than granite and has a rough, crystalline appearance. One of the most obvious advantages of this stone is its reasonable and low price.


 This stone is one of the inner igneous stones that has a dark color and coarse texture. The color of gabbro is green, black and greenish gray, which has a unique effect when polished. This stone is one of the stones used in the construction of counters, cabinets, tiles, floors, facades and building decorations. It has a high resistance to weathering and for this reason, this stone is used for building facades and floors.
