Granite is one of the longest lasting and toughest natural stones on the market, making it the perfect choice for any outdoor or indoor project. In 1822, an Austrian mineralogist named Friedrich Moh created a measurement of relative hardness based in a stone’s ability to withstand scratches. Because granite is composed of mainly feldspar and quartz, it has an exceptional resistance to scratches, which is why it is chosen for high traffic areas and has been considered one of the best building materials for thousands of years.
