They are hard and compact minerals. The word //stone// is used in the common language as in architecture and engineering to refer to any material of natural origin characterized by a high consistency.

What characteristics do stones have?
= Why are stones used in construction? = = = ==Because in their manufacturing processes it can be applied a variety of techniques, such as carving and engraving of the stone, aging, pigmentation, or protection, allowing them to endure over time as a genuine work of art. In addition to these, they have another uses such as: coating or plating walls, pillars, garden, terraces, fireplaces, floors, etc...== = = = STONE PARAGRAPH: FELIX AND ME =
 * ==Diamons, ruby, amatista and zafiro: are hard minerals, transparents, very valuable because of their rarity.==
 * ==The granite is a rock that can be cut and polish into specific forms and dimensions. It's hard, wear-resistant and resistant to the application of compression forces.==
 * ==The limestone is used in a wide range of products, from the cement to the extraction of lime.==
 * ==The marble has a great variety of colors, which makes it very valuable (vailabel) as a decorative element.==

==Stones are hard and compact minerals. The word stone is used in architecture and engineering to refer to a material of natural origin characterized by a high consistency. Stone is versatile and very useful in construction. ==

==Stone has many advantages and disadvantages. On the one hand, the advantages are durability, adaptability to sculptural treatment and easy to use in its own natural way; on the other, it has the following disadvantages: difficult to quarry, transport and cut, expensive and unstable with loads pushing at angles. There are several types of stonework : rubble and ashlar masonry. The first is simplest and cheapest stonework, and roughly broken stones of any shape bounded in mortar; the other, consists of regularly cut blocks and does not depend on strong bonding for stability, because it supports only direct downward loads.==

==In construction, stone is a good material because it resists deformation better than any other bonding material and it is strong enough to provide monolithic supports like in columns and piers, and beams like in lintels. Actually we can find historical monuments made of stone that have endured over time such as: the city of Petra in Jordan, the Pyramids in Egypt and the Great Wall of China ==
