For millennia, the sapphire has captivated humanity with its rich history, enduring beauty, and symbolic significance. As the recognized birthstone for September, this gemstone embodies fidelity, nobility, and a connection to the divine. While most readily associated with its classic blue hue, the sapphire presents itself in a remarkable spectrum of colors, each possessing unique allure and meaning. This article delves into the history, geological origins, gemological properties, and cultural significance of the September birthstone, exploring its journey from ancient reverence to modern-day adornment.
History and Lore
The sapphire’s story is interwoven with the narratives of ancient civilizations. In ancient Greece and Rome, blue sapphires were believed to offer protection from harm and ward off envy. These early cultures held the gem in high regard, associating it with safety and well-being. Ancient Persians even held the belief that the earth rested upon a colossal sapphire, responsible for the sky’s vibrant blue color.
Medieval Europeans attributed healing powers to the sapphire, believing it could cure plague boils and alleviate eye ailments, and even serve as an antidote to poison. Clerics of the Middle Ages favored sapphires, viewing the gemstone as a symbol of Heaven, reflecting its celestial blue tones. The stone’s association with wisdom and virtue further cemented its place among the elite.
Throughout history, sapphires have been intrinsically linked to royalty. They adorned the robes of kings and queens, signifying their power and status. Sapphire rings were worn when visiting oracles, believed to enhance the chances of receiving a prophetic message. The stone continues to be associated with significant life events, notably the celebration of 5th and 45th wedding anniversaries, and remains a popular choice for engagement rings, symbolizing enduring love and commitment.
Geological Formation and Sources
Sapphires belong to the corundum family, a crystalline form of aluminum oxide. The presence of trace elements, such as titanium and iron, imparts the characteristic blue color to most sapphires. Remarkably, the formation of sapphires requires an absence of silicone, a common element, making them relatively rare gemstones.
Historically, classical violet-blue sapphires originated from the Kashmir region of India, particularly between the late 19th and early 20th centuries. Sapphires from Kashmir are highly prized, and a gemstone from this region set a world record price-per-carat of $242,000 in 2015. Sri Lanka has also been a significant source of notable sapphires, including famous star sapphires like the Star of Adam, the Star of India, and the Star of Bombay.
Australia was once a major sapphire producer, but Madagascar has emerged as the leading source of sapphire gemstones since the 1990s. While blue sapphires remain the most well-known, sapphires occur in a wide range of colors, including violet, purple, green, pink, yellow, grey, black, brown, and even colorless varieties. Red corundum is classified as ruby, a distinct gemstone. The rare padparadscha sapphire, a pinkish-orange hue derived from the Sinhalese word for lotus flower, is considered particularly valuable. Some sapphires even exhibit a color-changing phenomenon, shifting between blue and purple depending on the light source.
Gemological Properties
Sapphires are renowned for their exceptional durability, ranking nine on the Mohs scale of hardness. This makes them highly suitable for everyday wear, resisting scratches and abrasions. Only diamonds, with a Mohs hardness of ten, surpass sapphires in terms of hardness.
Sapphires exhibit a full rainbow of colors, though the term "sapphire" typically refers to the blue variety. Sapphires are marketed according to their color, such as yellow sapphire or purple sapphire. A high-quality 1-carat blue sapphire can range in price from $3000 to $5000, though prices fluctuate daily.
Beyond color, sapphires can also display asterism, a phenomenon where a six-rayed star appears on the surface of the gemstone when viewed under specific lighting conditions. This effect is caused by the presence of microscopic inclusions within the stone.

Symbolism and Metaphysical Beliefs
Throughout history, sapphires have been imbued with profound symbolic meaning. They traditionally represent sincerity, truth, faithfulness, and nobility. Beyond these virtues, sapphires are considered protective gemstones, believed to shield the wearer from both physical harm and negative intentions.
In Buddhist traditions, sapphires were thought to promote spiritual enlightenment. Hindus utilized sapphires during worship, recognizing their sacred properties. Ancient Hebrews believed the Ten Commandments were inscribed on tablets of sapphire, though some historians suggest lapis lazuli may have been the stone referenced in biblical texts.
Sapphires are also associated with wisdom and divine favor, making them a favored gemstone among priests and religious leaders. The stone’s connection to the heavens reinforces its reputation as a symbol of spiritual insight and clarity.
Care and Cleaning
Sapphires’ exceptional hardness makes them well-suited for everyday wear. However, like all gemstones, they require proper care to maintain their brilliance. Sapphires can be cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals or abrasive cleaners, as these can damage the stone’s surface.
While durable, sapphires can undergo various treatments to enhance their color or clarity. Common treatments include heat treatment, which can improve color saturation, and diffusion treatment, which introduces color-causing elements into the stone. It is important to be aware of any treatments applied to a sapphire, as they can affect its value and care requirements.
Alternative September Birthstones
While sapphire reigns as the primary September birthstone, two alternatives offer equally compelling symbolism and beauty: lapis lazuli and aventurine. Lapis lazuli, a deep blue stone, shares similar metaphysical properties with sapphire, representing illumination, communication, and protection. Historically, lapis lazuli was sometimes misidentified as sapphire.
Aventurine, a green stone associated with the zodiac sign Virgo, is known as a stone of abundance, empathy, and creativity. It is also believed to be connected to the realm of the gods. These alternative birthstones provide options for those seeking a unique and meaningful gemstone to celebrate the month of September.
Conclusion
The sapphire stands as a testament to the enduring allure of gemstones. From its ancient origins as a symbol of royalty and protection to its modern-day status as a beloved birthstone, the sapphire continues to captivate with its beauty, durability, and rich history. Whether admired for its classic blue hue or its vibrant array of colors, the sapphire remains a treasured gem, embodying sincerity, faithfulness, and a connection to the celestial realm. Its geological rarity, combined with its enduring symbolism, ensures that the sapphire will continue to be cherished for generations to come.
