According to Gems N' Loans, a sapphire without any color prefix such as blue, refers to the blue mineral Corundum. A corundum is a crystalline form of aluminum oxide typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. However, the term Sapphire encompasses all other gem varieties and colors of Corundum as well, except Ruby which is the red variety of Corundum, which has its own name.
Like diamonds, there are lab created Sapphires, where the corundum is a synthetically produced crystal whose with hardness on the Mohs scale that is second to diamond, making it extremely durable. Durability is important because gemstones are susceptible to chipping.
Jewelers in Temecula often show case these gems and are offering 50% OFF on Sapphires for the month of September.
