A sapphire is a precious gemstone, typically known for its striking blue color, although it can also appear in other colors like pink, yellow, green, and even colorless. Sapphires belong to the corundum mineral family, and their color is primarily caused by trace elements such as iron and titanium. The most well-known and prized sapphires are those with a deep blue hue, often referred to as "royal blue."

Sapphires are extremely durable, scoring 9 on the Mohs scale of hardness (just below diamonds), making them ideal for jewelry like rings, necklaces, and earrings. Historically, they have been associated with wisdom, nobility, and purity, and they were believed to protect their wearers from envy and harm.

Sapphires are also significant in cultural and religious contexts, and their appeal spans many centuries, from ancient civilizations to modern times. They are often used in engagement rings, symbolizing both love and commitment.
