Granites are historically the most popular stone type used in countertop applications. This group includes many stone materials that are not true granites by geological definition. However, because their properties are so similar, they are grouped together as ‘granite’. These stones are known geologically as gabbro, anorthosite, gneiss, diabase, and diorite, to name a few. Whatever the name, these stones are some of the hardest of the common countertop stones, offering high levels of resistance to abrasion and scratching.
