What is the difference between Granite? Marble? Travertine?
Granite is unique among natural stones in hardness, composition and origin. Geologically, granite is an igneous rock, meaning that it was formed from a molten state. Most marbles, limestone and travertine are significantly "softer" than granite. High in quartz and feldspar, granite is highly resistant to scratching and heat. In the industry, natural stone is designated as a granite versus a marble or limestone or quartzite based on industry (versus geologic) testing regarding durability characteristics. Because of its durability, granite is recommended for use in kitchens over other natural stones.
