Granite is an igneous rock that is composed primarily of four minerals: quartz, feldspar, mica, and usually hornblende. Granite is formed from magma cooling very slowly, deep under the surface of the Earth. Depending on its location, the composition will vary, which is the ultimate reason for many different colors and patterns.
Marble is generally formed from limestone undergoing metamorphism. When exposed to extremes of pressure or heat limestone turns into calcite or dolomite crystals. Marble has been used in architecture and sculpture from as far back as the Ancient Greeks, and is still used heavily today in many construction projects.
Quartzite is a hard metamorphic rock which was originally sandstone. When sandstone is metamorphosed to quartzite the quartz grains re-crystallize, changing the original texture and structure of the sandstone. Quartzite is used today as a decorative stone, which has proven to be resilient to any wear in most applications.
Travertine is mainly formed by rapid chemical precipitation of calcium carbonate from solutions in surface and ground waters. It is often used for interior and exterior decorations as well as paving stones.
Limestone is a sedimentary rock composed mainly of calcite and aragonite. Certain types of limestone may contain small fossils and marine skeletal fragments that give the stone a natural, organic element.
