Sapphire is a precious gemstone, typically known for its striking blue color, though it can also come in a variety of other colors, such as pink, yellow, green, and even clear. It is a variety of the mineral corundum, with its blue hue primarily caused by trace amounts of iron and titanium. Sapphires are highly valued for their hardness (9 on the Mohs scale), making them durable and suitable for use in jewelry like rings, necklaces, and earrings.

Sapphires have a rich history and are often associated with wisdom, nobility, and purity. They are also the birthstone for the month of September. The name "sapphire" comes from the Greek word "sappheiros," meaning "blue stone." Historically, they have been worn by royalty and clergy to symbolize wealth, power, and divine favor.
