Paragraph 2
===According to the Collins English Dictionary, a stone is the hard compact nonmetallic material of which rocks are made. As in jewelry or masonry, the stone can be worked as stonework or bonding. Stonework is the art or process of working with the stone by losing its fragments (Rubble), **which is the cheapest and easiest stonework** and you may see them in walls, or by ashlar masonry **(cutting the stone regularly in rectangles).** By bonding, we understand that it is a particular method for a particular task, where the mortar is not essentially needed. ===

===Some of the advantages about working with stone are that it possesses special qualities needed for some constructions or treatment as it is its durability and adaptability, and it can also be used naturally. **When it is available it is the favorite material to be used when construction**. On the other hand, it is difficult to cut them or even transport them; it is expensive and weak in tension matters. ===
