Granite can be used not only on the exterior, but also in wet indoor environments such as bathrooms and toilets, because its porosity is low and it does not absorb water. According to the minerals in it, granite can be seen in gray, green, red and pink colors. Black granites with large feldspar grains or leopard granites are also considered as types of this stone that have a high price and are usually sold in large pieces.

Travertine

Wavy travertines are more expensive than the cloudy and windy ones.

The color of sandstone is grayish brown and yellow. Due to its sand structure, sandstone has a rough texture and does not absorb well. This type of stone absorbs water and its low bending resistance makes it easy to bend.
