History and Lore
Ancient Beliefs and Royal Associations
Sapphire has been a gemstone of great prestige since antiquity. In ancient Greece and Rome, it was believed to protect the wearer from harm and envy. The deep blue color was associated with the heavens, and the gem was thought to serve as a bridge between the earthly and the divine. Medieval clergy often wore sapphires to symbolize their connection to Heaven and to invite divine favor.
The Persians held a particularly poetic view of sapphire, believing that the earth rested on a massive sapphire, and that the blue of the sky was a reflection of this celestial gem. In ancient India, sapphire was considered a sacred stone, often used in religious rituals and temple adornments.
During the Middle Ages in Europe, sapphire was associated with purity and truth. It was used in crowns and royal regalia, symbolizing the divine right of kings. The stone was also believed to have healing properties—medieval Europeans thought that sapphire could cure eye diseases and was a powerful antidote to poison.
Modern Recognition as the September Birthstone
The designation of sapphire as the September birthstone is a relatively modern phenomenon. The recognition emerged in the United States through the efforts of the American National Association of Jewelers (now known as the Jewelers of America). In the 20th century, this organization standardized the list of birthstones, assigning sapphire to September. Since then, the designation has gained international acceptance, though it has occasionally been challenged by alternative traditions that recognize other stones, such as lapis lazuli or zircon, as September birthstones.
Sapphire’s enduring popularity as a birthstone is due in large part to its association with wisdom, loyalty, and nobility—qualities that resonate deeply with those born in September.
Geological Formation and Sources
What Is Sapphire?
Sapphire is a gemstone belonging to the corundum species, which is composed of aluminum oxide (Al₂O₃). While sapphires are most commonly known for their blue color, they can occur in a wide range of hues, including pink, yellow, green, and even colorless. The blue coloration is primarily due to the presence of trace elements such as iron and titanium.
Sapphires form under high-pressure and high-temperature conditions, typically deep within the Earth’s crust or in metamorphic rocks. The gemstone is often found in igneous and sedimentary rocks, particularly in locations with a history of volcanic activity or regional metamorphism.
Major Sources of Sapphire
Sapphire is mined in various parts of the world, with some of the most renowned sources including:
- Myanmar (Burma): Known for producing the highest quality blue sapphires, often with a rich cornflower blue color.
- Sri Lanka: A major source of sapphires, including both blue and other colored varieties.
- Madagascar: A significant modern producer of sapphires, with a wide range of colors and high-quality stones.
- Australia: Famous for its large sapphires, often with a lighter blue hue.
- Nepal, Thailand, and Tanzania: Also contribute to the global sapphire trade, each producing unique color variations.
The geological conditions in these regions, particularly the presence of trace elements and the intensity of heat and pressure, contribute to the formation of sapphires with distinct characteristics.
Gemological Properties
Physical and Optical Characteristics
Sapphire is one of the hardest gemstones, with a Mohs hardness of 9, second only to diamond (which has a hardness of 10). This makes it highly durable and suitable for everyday wear, particularly in jewelry such as rings and bracelets.
Some key gemological properties of sapphire include:
- Color: While blue is the most famous color of sapphire, the gemstone can appear in nearly every color of the rainbow except red (which is classified as ruby). The blue color is typically caused by trace amounts of iron and titanium.
- Clarity: Sapphires are often found with inclusions, which are natural imperfections that can be seen under magnification. These inclusions are not always considered flaws but can be used to identify the stone’s origin.
- Luster: Sapphire has a vitreous (glassy) luster, giving it a brilliant, reflective surface.
- Refractive Index: Sapphire has a refractive index between 1.76 and 1.78, which contributes to its sparkle and brilliance.
- Specific Gravity: The density of sapphire is approximately 3.95 to 4.03, making it a relatively heavy gemstone.
- Cleavage and Durability: Sapphire has no cleavage, meaning it does not split easily along any natural planes. This makes it a very tough gemstone, ideal for use in jewelry.
Color Variants and Special Cuts
While blue sapphires are the most well-known, other colors include:
- Padparadscha: A rare and valuable variety with a pink-orange hue, named after the Sri Lankan term for "lotus flower."
- Yellow Sapphire: Often found in India and Thailand, these sapphires are typically colored by trace amounts of iron.
- Green Sapphire: Colored by iron and chromium, these sapphires are less common and often confused with emeralds.
- Colorless Sapphire: Also known as white sapphire, these are essentially colorless corundum and are sometimes used as a more affordable alternative to diamond.
Sapphires are often cut into various shapes, including round, oval, cushion, and emerald cuts. The choice of cut can influence the gemstone’s brilliance and appearance, with the most popular being the round brilliant cut.

Care and Cleaning
How to Care for Sapphire
Given its high hardness and durability, sapphire is one of the most resilient gemstones, making it ideal for everyday wear. However, like all gemstones, it requires proper care to maintain its beauty and longevity.
- Cleaning: Sapphire can be cleaned using warm, soapy water and a soft brush. Ultrasonic and steam cleaners are also safe for sapphire, as long as the stone is free of any inclusions that could be damaged by the process.
- Storage: Sapphires should be stored in a soft, padded container to prevent scratches from other gemstones. Avoid storing them with diamonds or other very hard materials.
- Avoiding Harsh Chemicals: While sapphire is generally resistant to most chemicals, it is best to avoid exposing it to harsh substances such as bleach, ammonia, or strong acids. These can potentially damage the surface of the stone or any treatments it may have undergone.
- Professional Maintenance: For valuable sapphire jewelry, it is recommended to have it inspected and cleaned by a professional jeweler at least once a year to ensure its continued brilliance and structural integrity.
