Onyx is a magnificent and beautiful stone, which is why, in addition to being used in building structures, it is also used to make expensive sculptures and decorative items

Marble is a natural and attractive Stone that is very similar in appearance to Marble and is often confused with it. Some even think that these two Stones are one.
Marble is one of the calcareous stones and due to its internal impurities, it has a cream to gray colors. The main constituent of marble is calcium carbonate and other materials such as calcite and dolomite can be mentioned in the structure of this stone. The structure of magnesium carbonate is also seen in Semi-marble. Based on this structure, Semi-marble is divided into dolomitic, calcite, and magnesium marbles.
There are different streaks inside the Semi-marble stones. These streaks are often made of quartz, hematite, limonite, and pyrite. Due to these streaks and their percentage, the color of the stone will also change. Marble is seen as white pure marble.
This stone has good abrasion and flexural resistance and is very suitable for indoor and outdoor uses of the building. This stone is one of the heavy stones in terms of weight and has a relatively high tolerance against heat, sunlight, temperature changes, etc. What is clear; due to the calcareous nature of this rock, water or Chemicals should be expected to penetrate to some extent.
Marble is processed in the form of slabs, tiles, stairs, etc. and it is polished and strengthened with the help of resin and epoxy. The most popular marbles in the Middle east are Dehbid, Khoy, Peacock, Abadeh marble, Advari Semi-marble, and so on. Marble or Onyx is one of the stones that has been seen in structures all over the world since ancient times.
Marble is a metamorphic stone. Lime has withstood a lot of pressure and heat in the subsoil. The main mineral is marble calcite and due to the presence of impurities that may be inside it; it takes on different colors. Marble is one of the most durable Natural stones that is found in abundance in countries such as Italy and the Middle East.
Onyx is a magnificent and beautiful stone, which is why, in addition to being used in building structures, it is also used to make expensive sculptures and decorative items. Marble has a high resistance to water and heat penetration and is also very resistant to pressure, scratches, and chemicals. Even this stone does not change color in the face of external factors such as rain and sunlight. It is safe to say that marble is the only stone that can be used without restriction in all parts of a building.
Marble is suitable for use on stairs because it is resistant to abrasion and scratches. It can be used for toilets, baths, and humid places because it has a very low absorption value. Finally, it is very suitable even as a floor for open parts of the building. The amazing property of marble is the passage of light.
That is if light shines on the marble; due to the internal structure of the stone, light passes through it and returns it to the environment. This makes the place where the marble is used look brighter. Also, marble is a soothing stone that gives the environment a calm and pleasant atmosphere. Marble is found in different colors in nature.
But the onyx stone is pure white and there are no streaks in it. But blue, orange, pink, and green marbles are also very rare and expensive and are used to make expensive decorative materials.
Marble is a granular metamorphic rock, it is derived from limestone or dolomite and It consists of a mass of interlocking grains of calcite or the mineral dolomite. Impurities in the limestone can recrystallize during metamorphism, resulting in mineral impurities in the marble, most commonly graphite, pyrite, quartz, mica, and iron oxides. In sufficient amounts, these can affect the texture and color of the marble. Marble is a rock on account of metamorphism of sedimentary carbonate rocks, maximum normally limestone or dolomite rock. At the beginning, the metamorphism of the limestone and 1200-1,500 bar and between 125-180 degrees Celsius remote exposure to high pressure and temperature of the marble there. The metamorphism of the limestone is required by marble, extra iron and graphite (in smaller quantities). Marble deposits can be found in various countries around the globe. The United States of America is also a high level Marble producer, with states such as Alabama and Texas having especially large deposits to be found within their borders. It is, however, Italy, China, India, and Spain who dominate global Marble production. Marble takes place in massive deposits that may be hundreds of toes thick and geographically good sized. Dimension stone is produced by sawing marble into portions of particular dimensions. We have an article about “the makes use of of marble” that includes pictures and descriptions of marble in many kinds of makes use of.
