Granite is igneous – meaning it is formed by extreme heat and volcanic action. Its characteristic colors include a huge variety and mixes of color. Granite can take a high polish.
Limestone is sedimentary – meaning it is formed by the action of water and great pressure. Its characteristic colors include neutrals, off-white, beige, tan, taupe, light blue grey. The look of limestone is created by the interaction of sediment deposits and shells with geological activity. Limestone finishes are usually honed and typically do not hold a high gloss polish.
Marble is the metamorphic product of limestone – meaning it is formed when heat and great pressure are applied to limestone. Its characteristics include a huge variety and mixture of colors. The veins found in marble are created by the interaction of mineral deposits with geological activity. Marble can take a high polish due to its hard surface.
Slate is metamorphic – meaning it is formed under great pressure from sediment. It has a huge variety of characteristic colors that often vary widely. Slate has a natural cleft finish.
Travertine is a banded, compact variation of limestone. Its characteristic colors include neutrals, off white, beige, tan, and yellow. The look of travertine is created by the interaction of gas, shells and water with geological activity. Travertine finishes are usually honed, but some will hold a polish.
Soapstone is a unique rustic looking material. It is a talc-schist which is a type of metamorphic rock. It is produced by dynamo-thermal metamorphism and metasomatism which occurs in zones where tectonic plates are subducted by heat and pressure with an influx of fluids, but without melting. It's unusual thermal properties and closely-packed make up are perfect for large spaces and heated flooring. This stone is heat and acid resistant.
