Original Note:
Granite is not "the strongest rock next to a diamond." Granite is made of many minerals, the hardest of which is quartz, which is softer than minerals like topaz and corundum. In addition, rocks break between mineral grains, not through individual minerals. Learn more: https://www.nps.gov/articles/mohs-hardness-scale.htm
