Sapphire is a precious gemstone known for its stunning blue color, though it can also come in a variety of other hues, including pink, yellow, green, and even colorless. The stone is a variety of the mineral corundum, the same mineral that forms rubies, with its blue color typically caused by trace amounts of iron and titanium. Sapphires are known for their remarkable hardness, ranking 9 on the Mohs scale, making them highly durable and suitable for various types of jewelry.
In addition to their physical beauty, sapphires are often associated with symbolism and meaning, representing wisdom, loyalty, and nobility. They have been used throughout history by royalty and the wealthy. Sapphires are commonly cut into round, oval, cushion, and emerald shapes, and their clarity and color are key factors in determining their value.
