Sapphires are precious gemstones known for their striking beauty and durability. They are most commonly recognized for their deep blue color, but they can actually come in a variety of colors, except red (which is classified as ruby). Sapphires are composed of corundum, a mineral made of aluminum oxide, and their hardness ranks 9 on the Mohs scale, making them one of the hardest gemstones available.

In terms of metaphysical meanings, sapphires are often associated with wisdom, loyalty, and nobility. They are believed to promote mental clarity, enhance intuition, and provide protection against negative energies. Many also view sapphires as symbols of love and commitment, which is why they are often used in engagement rings. Their vibrant colors and optical properties make them a favorite among gemstone enthusiasts, reflecting a range of meanings tied to emotional balance and spiritual insight.
