Sapphire is a precious gemstone, primarily known for its striking blue color, although it can come in a variety of hues, including pink, yellow, green, and even colorless. It is a variety of the mineral corundum, composed of aluminum oxide, and is second in hardness only to diamond, rating 9 on the Mohs scale. Sapphires are typically associated with qualities such as wisdom, nobility, and loyalty.

The most coveted sapphires are deep blue in color, often with a rich, velvety appearance. They are frequently used in fine jewelry, including rings, necklaces, and earrings, and are also popular for use in high-end watches.

Sapphires are found in various locations around the world, including Sri Lanka, Myanmar, Thailand, and Kashmir. The "Kashmir sapphire," known for its vivid blue and velvety texture, is particularly rare and valuable.
