For millennia, the sapphire has been a cornerstone of human adornment, revered for its profound blue hue and imbued with legendary significance. As the primary birthstone for September, sapphire transcends mere decoration; it is a symbol of wisdom, fidelity, and heavenly protection. While blue sapphire is the most iconic and widely recognized variety, the gemstone family of corundum encompasses a breathtaking spectrum of colors, each with its own unique allure and value. The journey of sapphire from ancient Persian lore to modern jewelry boxes is a testament to its enduring appeal. This article explores the multifaceted world of September's birthstone, delving into its historical and cultural significance, geological origins, precise gemological properties, and the metaphysical beliefs that have surrounded it for centuries.
History and Lore: The Stone of Kings and Clerics
The association of sapphire with the month of September has deep historical roots, formalized in the late 19th and early 20th centuries. The modern standardized lists began in 1870 when Tiffany & Co. published a pamphlet of birthstone poems, which designated sapphire for September. This was followed by the first official standardized list in 1912 by the American National Association of Jewellers (now Jewellers of America), and a subsequent 1937 list by the British National Association of Goldsmiths, solidifying sapphire’s place as September’s gem. However, the gem's reverence predates these formal lists by thousands of years.
Ancient cultures attributed immense power and meaning to the blue sapphire. The elite of ancient Greece and Rome believed that blue sapphires offered protection from harm and envy. In the Middle Ages, clerics wore sapphires as they were thought to symbolize Heaven and divine favor. This spiritual connection was so profound that ancient Persians believed the Earth rested upon a giant sapphire, and its reflection in the sky gave the heavens their blue color. The gemstone’s name itself is derived from the Latin sapphirus and Greek sappheiros, both meaning 'blue' or referring to a 'precious stone.' Beyond its protective qualities, sapphire has long been a symbol of sincerity, truth, faithfulness, and nobility. It has adorned royalty and the robes of the clergy for countless centuries, making it a gemstone of both earthly power and spiritual devotion.
The healing powers attributed to sapphire are also a noted part of its historical lore. Medieval Europeans believed the stone could cure plague boils and diseases of the eye, and it was also thought to serve as an antidote to poison. The gemstone's association with romance and fidelity is evident in its role as a celebratory gem for wedding anniversaries; blue sapphire is traditionally given for the 5th and 45th wedding anniversaries, while the Star Sapphire marks the 65th. The historical narrative of sapphire is one of a gemstone cherished not only for its beauty but also for its perceived ability to connect the wearer to higher realms of wisdom and truth.
Geological Formation and Global Sources
Sapphire is a variety of the mineral corundum, an aluminum oxide (Al₂O₃). Its formation requires specific geological conditions, typically occurring in metamorphic and igneous rocks. The iconic blue color of sapphire is primarily due to trace amounts of iron and titanium impurities within the crystal structure. The gemstone is found in various locations around the world, each source contributing to the market's diverse offerings.
One of the most historically significant and valuable sources of blue sapphire is Myanmar (formerly Burma). The region is renowned for producing gems of exceptional color and clarity. A famous example is the Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone unearthed in Myanmar. This particular stone exemplifies the high-quality material for which the region is known.
Kashmir, a region located in the northern part of the Indian subcontinent, is another legendary source. Sapphires from Kashmir are celebrated for their velvety, cornflower-blue hue and are among the rarest and most expensive in the world. The gemological community holds stones from this origin in particularly high regard.
Beyond these historic locations, commercial-grade sapphires are also found in East Africa, Australia, and Montana, USA. These sources provide a more accessible range of sapphire quality and color, catering to a broader market. The mining of sapphires, like many gemstones, can involve ethical and environmental considerations. As a result, lab-created sapphires have become a popular and affordable alternative, offering the same chemical and physical properties as natural stones while circumventing the issues associated with mining. For the opaque alternative September birthstone, lapis lazuli, the primary source for over 6,000 years has been Afghanistan, where it continues to be mined today.
Gemological Properties: The Science of Corundum
Understanding the gemological properties of sapphire is essential for appreciating its value and durability. As a member of the corundum family, sapphire shares key characteristics with ruby, its red counterpart. The following table summarizes the core gemological data for sapphire, based on authoritative sources.

The most critical property for daily wear is its hardness. On the Mohs scale, sapphire registers a 9, making it second only to diamond (10) in durability. This exceptional hardness means sapphires are highly resistant to scratches and can withstand the rigors of regular wear, making them an excellent choice for engagement rings and everyday jewelry. This durability is a key factor in their enduring popularity.
While "sapphire" most commonly refers to the blue variety of corundum, the gemstone is available in a rainbow of other colors, known as "fancy sapphires." These can include pink, yellow, green, orange, and purple. The most sought-after and rarest of these is the padparadscha sapphire, a delicate blend of pink and orange, named after the Sinhalese word for "lotus blossom." The value of a sapphire is determined by a combination of factors including color, clarity, cut, and carat weight, with untreated stones from prestigious origins like Kashmir commanding premium prices.
Symbolism and Metaphysical Beliefs
The symbolism of sapphire is deeply intertwined with its historical and cultural legacy. Across various eras and civilizations, the gem has been a powerful emblem of virtue and insight. Its primary associations are with wisdom, loyalty, and truth. The deep blue color is often linked to the sky and the heavens, reinforcing its connection to divine knowledge and spiritual purity. For this reason, it has been a favored stone among philosophers, royalty, and religious leaders who sought to embody these ideals.
In addition to its symbolic meanings, sapphire has been attributed with a range of metaphysical properties. As mentioned in historical lore, it was believed to possess healing energies, capable of curing physical ailments and protecting against poison. In a more modern metaphysical context, sapphire is often associated with mental focus and clarity. It is said to aid in concentration, helping the wearer to achieve their goals and find peace of mind. The stone is also linked to the throat and third eye chakras in certain belief systems, promoting clear communication and intuitive insight.
It is important to note that while these metaphysical beliefs are a significant part of sapphire's cultural history, they are not supported by scientific evidence. However, for many individuals, these symbolic and spiritual associations add a profound layer of personal meaning to the gemstone, enhancing its value beyond its physical attributes.
Care and Cleaning
Given its exceptional hardness of 9 on the Mohs scale, sapphire is a relatively easy gemstone to care for. It is durable enough for everyday wear and is resistant to most scratches and abrasions. However, like all gemstones, it requires proper maintenance to preserve its brilliance.
The best method for cleaning sapphire jewelry is to use warm, soapy water and a soft brush, such as a toothbrush. Gently scrub the stone and its setting to remove any dirt, oil, or residue. Rinse thoroughly with clean water and pat dry with a soft, lint-free cloth. It is advisable to avoid harsh chemicals, such as household cleaners or bleach, which could potentially damage the metal setting or, in rare cases, affect any treatments the stone may have undergone.
Ultrasonic and steam cleaners are generally safe for untreated sapphires, but caution is advised for stones that have been fracture-filled or have undergone other complex treatments. When in doubt, it is always best to consult a professional jeweler. Storing sapphire jewelry separately from other gems and metals can prevent scratches, though its hardness makes it less likely to be scratched by most other materials.
Alternative September Birthstones
While blue sapphire is the official and most recognized birthstone for September, some traditional lists and cultural practices include alternative gems. The most notable alternative is Lapis Lazuli. Unlike sapphire, which is a single mineral, lapis lazuli is an aggregate rock composed primarily of the mineral lazurite, with calcite and pyrite veins, giving it a deep royal blue color with golden flecks. It has been used for thousands of years in jewelry and art, with its most famous source being Afghanistan. Lapis lazuli carries its own rich symbolism, often associated with wisdom, truth, and self-awareness.
Other historical and alternative lists, such as those based on zodiac signs or guardian angels, may include additional stones like Jacinth (Hyacinth), Chrysoprase, and Jasper for those born in September. However, these are not part of the modern, standardized birthstone lists and are considered niche alternatives.
Conclusion
Sapphire stands as a gemstone of unparalleled significance, perfectly capturing the essence of September. Its journey from the ancient belief that it held up the sky to its modern status as a symbol of wisdom and fidelity is a story of enduring fascination. As the primary birthstone for September, its deep blue hue evokes the crisp clarity of autumn skies, while its rainbow of fancy colors offers a personal connection for every wearer. With a hardness of 9 on the Mohs scale, it is a gem of both beauty and resilience, suitable for a lifetime of wear. Whether chosen for its historical lore, its scientific marvel, or its breathtaking beauty, sapphire remains a timeless treasure, embodying the noble ideals of truth, loyalty, and celestial wonder.
