Sapphire is a precious gemstone, a type of corundum, known for its diverse range of colors, with blue being the most well-known. While typically blue, sapphires can be found in nearly any color except red, which is classified as a ruby. The name "sapphire" comes from the Greek word "sappheiros," meaning "blue stone".

Here's a more detailed description:

• Corundum:

  Sapphires are a variety of the mineral corundum, which is composed primarily of aluminum oxide (α-Al2O3).

• Color:

  Blue is the most common color of sapphire, but they can also be found in yellow, orange, purple, green, and other colors, often referred to as "fancy" sapphires.

  Sapphires are known for their high hardness, ranking 9 on the Mohs scale, making them very durable and suitable for jewelry.
