What is a corundum?

Corundum is a mineral that is best known for its gemstone varieties, sapphire and ruby. But what exactly is corundum, and what makes it so special? Corundum is a crystalline form of aluminum oxide, and it is one of the hardest minerals on earth, second only to diamond. It is also one of the most common minerals in the earth's crust, and can be found in a variety of colors, including blue, pink, yellow, green, and even colorless. The gemstone varieties of corundum, sapphire and ruby, are prized for their beauty, durability, and rarity. Sapphires come in a range of colors, from deep blue to pink, yellow, and even white. Rubies, on the other hand, are known for their deep red color and are one of the most valuable gemstones in the world. Corundum is formed under high pressure and high temperature conditions deep within the earth's crust. It is often found in metamorphic and igneous rocks, and can also be found in alluvial deposits, where it has been eroded from its original source and carried downstream by water. In addition to its use as a gemstone, corundum has many industrial applications due to its hardness and durability. It is used in the manufacture of abrasives, cutting tools, and electronic components, among other things. Overall, corundum is a fascinating mineral that has captured our attention for centuries. Whether you are admiring a stunning sapphire or using an abrasive tool to cut through metal, you are experiencing the remarkable properties of corundum.
