The mineral commonly used to make jewelry, decorative items, mechanical parts, and abrasives is corundum. Corundum is a crystalline form of aluminum oxide and is highly valued for its hardness, making it suitable for abrasive applications. Additionally, when corundum is colored by trace elements, it can form gemstones such as sapphires and rubies, which are widely used in jewelry.
