Sapphire has been a treasured gemstone for millennia, with historical accounts tracing its use back to ancient civilizations.

In ancient times, sapphire was believed to have protective and purifying properties. It was worn by priests and monarchs as a symbol of divine favor and was thought to bring wisdom and clarity to the wearer.
In medieval Europe, sapphire was considered a sacred stone, often worn by clergy to symbolize the heavens.

Geological Formation and Sources
Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep blue color of most sapphires is due to trace amounts of iron and titanium. While sapphire is best known for its blue variety, it can occur in almost every color of the spectrum, except red. When corundum is red, it is classified as a ruby.
Sapphires are formed under intense heat and pressure deep within the Earth's crust, often in metamorphic or igneous rocks. These conditions allow the aluminum oxide to crystallize into sapphire, with impurities determining the stone's color. The most famous blue sapphires are found in Sri Lanka, Myanmar, and Thailand, but sapphires are also mined in other parts of the world, including Australia, Madagascar, and the United States.
Sapphires are known for their durability, ranking 9 on the Mohs scale of hardness. This makes them suitable for everyday wear, though they can still be scratched by diamonds. The clarity, color, and cut of a sapphire significantly affect its value and beauty. High-quality sapphires are rare and highly sought after, making them one of the most valuable gemstones in the world.
Gemological Properties of Sapphire
Physical and Chemical Characteristics
Sapphire is one of the hardest natural gemstones, with a hardness of 9 on the Mohs scale. This means it can withstand most types of wear and tear, making it ideal for use in rings, bracelets, and other jewelry. However, while it is hard, sapphire can still be chipped or fractured if struck in the right direction, particularly along its cleavage planes.
The chemical composition of sapphire is aluminum oxide (Al₂O₃). The blue color of most sapphires is due to trace amounts of iron and titanium. Other impurities can result in sapphires that range from pink to yellow, green, and even colorless. The most valuable sapphires are those with a deep, rich blue color, often described as "cornflower blue."
Sapphires have a refractive index between 1.76 and 1.78, which contributes to their brilliance and fire. They are also known for their luster, which is described as vitreous, or glassy. The clarity of a sapphire can vary, with some stones containing inclusions that are visible to the naked eye, while others are nearly flawless.
Color and Value
Sapphire is available in a wide range of colors, but the most famous and valuable is the deep blue variety. The intensity and tone of the blue color are key factors in determining a sapphire's value. A sapphire with a medium to deep blue color is generally more desirable than one that is too light or too dark.
Other factors that affect the value of a sapphire include its clarity, cut, and carat weight. A well-cut sapphire will display more brilliance and fire, while a poorly cut stone may appear dull or lifeless. Larger sapphires are also more valuable, as high-quality large sapphires are rare.
Symbolism and Metaphysical Beliefs
Sapphire has long been associated with wisdom, truth, and spiritual clarity. In ancient times, it was believed that sapphire could protect the wearer from harm and envy, making it a popular gemstone among scholars, clergy, and royalty.

Care and Maintenance of Sapphire
Due to its hardness and durability, sapphire is a relatively easy gemstone to care for. However, it is still important to handle it with care to avoid damage. Sapphire can be cleaned using a mild soap and warm water, and it can be soaked in a solution of water and dish soap for a few minutes before being rinsed and dried with a soft cloth.
Sapphire should be kept away from harsh chemicals, as they can cause damage to the stone or its setting. It is also a good idea to store sapphire jewelry separately from other gemstones to prevent scratches and abrasions.
If a sapphire becomes dull or cloudy, it can be professionally cleaned and polished by a jeweler. This will help to restore its brilliance and luster, ensuring that it continues to look beautiful for years to come.
