Corundum: The Mineral Behind Ruby and Sapphire Gem Varieties
Corundum is a rock-forming mineral composed of aluminum oxide, but you will better recognize its crystalline gem varieties: ruby and sapphire. The distinguishing feature of these variaties is their coloring. Ruby is red, while sapphire can come in various hues, the most popular and sought-after being the blue variety.

Corundum is a relatively hard mineral, coming in at a nine on the Mohs gemstone hardness scale. This quality could certainly contribute to its popularity in the world of jewelry, as the hardness of the gemstone lends itself to use in a variety of interesting and beautiful fine jewelry styles and settings.
Natural rubies and sapphires may have their color deepened through the process of heat treatment. This process gives the gemstone's color a more enhanced appearance by exposing it to very high heated temperatures. Additionally, naturally colorless or pale-colored corundum is sometimes dyed to achieve vibrant and desirable colors.

The word "corundum" derives from the Tamil word "Kurundam" which originally comes from the Sanskrit word "Kuruvinda" meaning ruby. Corundum is a rock-forming mineral composed of aluminum oxide. Its red and blue varieties are well-known as ruby and sapphire.
Corundum Jewelry Care & Handling
Corundum is a relatively hard crystalline mineral, and an excellent choice for everyday, normal wear. Still, it should be protected from scratches and sharp blows. For cleaning, warm soapy water and a soft cloth are safe. Avoid chemicals, heat, and ultrasonic cleaners if the gemstone is dyed. If your corundum is dyed, or has a scratch or fracture, consider a gentler clean by hand with a damp cloth. Store your corundum rings, necklaces, bracelets and earrings in your Ross-Simons presentation box.
