Sapphires are precious gemstones that belong to the corundum mineral family. They are most commonly known for their striking blue color, but they can also be found in various shades, including pink, yellow, and green. The color of a sapphire is determined by the presence of trace elements, such as iron and titanium. These gemstones are highly valued for their durability and brilliance, making them popular choices for jewelry, especially in engagement rings. Sapphires are often associated with royalty and wisdom, and they have been used in various cultures for centuries as symbols of nobility and protection.
