Natural stones are considered to be the oldest building material known to man. The use of natural stone materials adds both permanence and elegance to modern construction. Any natural stone, or combination of natural stones, will enhance your building space with an aesthetically pleasing image while providing a facade of high performance with low maintenance.
By geological definition, there are hundreds of stone types commonly used as dimension stone products. The commercial definitions of stones are much broader, allowing stones with similar mineralogy, workability, performance, and behavior to be combined into one classification, discounting the fact that they may be scientifically classified as different stone types. For example, stones such as gabbro, diabase, diorite, anorthosite, etc., are marketed commercially as granites because their properties are similar, even though they are not true granites by geological definition.

Most stones used in dimension stone applications will fall under one of five commercial definitions: Granite, Marble, Limestone, Quartz-Based, or Slate.
