Based on this, marble reserves are estimated at 2.16 billion, granite at about 1.5 billion tons, travertine at about 450 million tons, and marble at 44 million tons. The number of decorative Natural Stones extracted in the country last year was 10.6 million tons. The amount of extraction of decorative stones in the country last year was 10.6 million tons. 

The stone must be in harmony with the part used. For example, a stone that has a high ability to absorb water is not suitable for use in bathrooms, toilets, or any place that deals with moisture. Building stone must be strong. This stone must be resistant to pressure and shocks that may enter it accidentally. The thickness of the stone is very important for use in the building. 

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. 

When it comes to buying building facade stone; Travertine is one of the first choices. Travertine is very popular among people for building. Travertine is also a good stone for the flooring. Travertine is one of the porous limestone. This rock is the result of water-sediment in mines and hot springs or seabed sediments. 

Crystal Marble is one of the most beautiful stones in the Middle East market. Calcareous or dolomitic crystalline rock. Due to the high pressure and temperature that this rock has endured under the underground layers; it is also called crystal metamorphic rock. Crystal Marbles belong to the large family of marbles. 

Granite is an example of very hard and durable stones and has high polishing ability. Granite stones are found in red, black, brown, chocolate, pink, blue and green. Their grain size is large and visible to the naked eye. The resistance of this product is higher than different types of marble and travertine, and its polished and shiny surface is more preserved. 

Marbles are rocks with simple mineralogical composition, but despite this, investigations on weathering phenomena of marble artifacts show very distinct behaviour for different marble types. 

The advantages of travertine stone are good resistance to cold and heat, adhesion to mortar and also very reasonable price. Of course, because the stone is sedimentary, very cold weather can lead to its crushing.

It can be said that it is a stone between marble and lime found in abundance near hot springs, especially limestone caves. The large cavities in the texture of this rock, as mentioned, are caused by gases trapped in hot water and make the surface of the rock, not polished and slippery, and a good choice for the floor of places that experience high humidity.

Travertine stones are usually available in ivory white or completely white and caramel. More common colors are naturally more economical as well, while stones with rarer colors are often much more expensive.

When the sandstone is transformed into quartzite, the quartz grains that were already there are crystallized again along with the cementitious material that was previously present in the sandstone, and the new quartz crystals are fused together. Most or all of the old sandstone texture and sedimentary structure will be completely removed by metamorphism and replaced by a new structure.

The formation of rocks, which are sandstones, is such that they are permeable to water and their porosity is such that they can hold large amounts of water, which makes them precious watersheds. Fine-grained watersheds such as sandstones are more prone to filtering contaminants from the surface than rocks such as limestone and other rocks formed by seismic activity. 

Synthetic Azure StonesIn the field of production of synthetic azure stone, although many jewelers do not consider it a ‎fundamental center. In 1954, artificial glassware such as spinel was dyed with cobalt oxide and ‎sold as lapis lazuli, which is easy to detect because it does not contain any inclusions or ‎substances such as pyrite.‎

The color, transparency and texture of the stone is one of the most important factors in determining the price of jade. The darker the color of the jade, the higher its value and price. 

Egypt is one of the northeastern countries of Africa. It borders Libya to the west and Sudan to the south. Egypt is bordered by the Mediterranean Sea to the north, Israel by land on the Sinai Peninsula, and Palestine on the Gaza Strip. The north of Egypt generally has a pleasant climate due to its proximity to the Mediterranean Sea.
