Due to this property, it is often used in sandpaper, grinding wheels, and cutting tools. In addition to its performance in abrasives, corundum also comes in various forms, including sapphires and rubies, which are valued as gemstones. Its durability makes it an excellent choice for industries requiring effective materials to shape or finish different surfaces, highlighting its versatility beyond jewelry.
