Sapphire is a precious gemstone, best known for its rich blue color, although it can come in a range of hues, including pink, yellow, green, and even colorless. It is a variety of the mineral corundum, with its blue color primarily caused by the presence of iron and titanium. Sapphires are second in hardness only to diamonds, making them highly durable and suitable for daily wear, especially in engagement rings and other fine jewelry.

Sapphires are often associated with qualities such as wisdom, loyalty, and nobility, which is why they have been used in royal crowns and religious artifacts for centuries. The most prized sapphires are often those with a deep, rich blue color, sometimes referred to as "cornflower blue." However, sapphires of other colors, called "fancy sapphires," are also highly valued, especially when they display strong and vibrant hues.

One of the most famous sapphires is the "Star Sapphire," a variety that exhibits a star-like pattern on its surface, caused by inclusions within the stone. The sapphire's symbolic associations, as well as its stunning appearance and exceptional durability, continue to make it one of the most sought-after gemstones.
