Sapphire, a gemstone steeped in history and revered for its captivating beauty, holds the distinguished position as the primary birthstone for September. Celebrated across cultures for millennia, this precious gem is more than just a visually stunning adornment; it embodies sincerity, truth, and nobility. This article delves into the fascinating world of sapphire, exploring its historical significance, geological origins, gemological properties, and enduring symbolism.
History and Lore
The history of sapphire is interwoven with tales of royalty, spirituality, and protection. Ancient civilizations, including those of Greece and Rome, held sapphires in high esteem, believing the blue variety shielded wearers from harm, envy, and even poison. Rulers and aristocrats adorned themselves with sapphires, not only for their aesthetic appeal but also as symbols of power and wisdom. Medieval Europeans attributed healing properties to the stone, believing it could cure plague boils and eye diseases. Clergy of the Middle Ages favored sapphires, associating the gem with Heaven and divine grace.
Ancient Persians held a particularly striking belief, imagining the earth rested upon a colossal sapphire, which was responsible for the sky’s blue hue. This reverence for sapphire extended into more recent history, with notable figures like Napoleon Bonaparte presenting his bride-to-be with a sapphire engagement ring in 1796. The association with romance and commitment continued with Princess Diana’s iconic 18-carat sapphire engagement ring, now worn by Catherine, Princess of Wales, a modern testament to the gem’s enduring appeal. Sapphires are also traditionally linked to the 5th and 45th wedding anniversaries, and even the 65th jubilee, as exemplified by Queen Elizabeth II’s Sapphire Jubilee in 2017.
Geological Formation and Sources
Sapphires belong to the corundum family, a crystalline mineral composed of aluminum and oxygen. The characteristic blue color of most sapphires arises from the presence of trace elements, specifically titanium and iron. However, the formation of sapphire requires a unique geological environment – one devoid of silicon. The absence of this common element is a key factor in the gem’s relative rarity.
While blue is the most recognized color, sapphires actually occur in a spectrum of hues, including violet, purple, green, pink, yellow, grey, black, and even clear. Red corundum, however, is classified as ruby, a distinct gemstone. Any sapphire displaying a color other than blue or red is considered a “fancy color” sapphire, with the padparadscha variety – a pinkish-orange hue reminiscent of a lotus flower – being particularly rare and prized. Some sapphires even exhibit color-changing properties, shifting between blue and purple depending on the light source.

Gemological Properties
Sapphires are renowned for their exceptional hardness, ranking 9 on the Mohs scale. This durability makes them highly suitable for everyday wear, including engagement rings. The gem’s chemical formula is Al₂O₃ (aluminum oxide).
Here's a summary of key gemological properties, based on the provided information:
| Property | Description |
|---|---|
| Mineral | Corundum (Aluminum Oxide) |
| Chemical Formula | Al₂O₃ |
| Hardness (Mohs) | 9 |
| Color | Typically blue, but also violet, purple, green, pink, yellow, grey, black, brown, and clear. Red corundum is ruby. |
| Rarity | High, due to the need for silicon-free formation environments. |
Cleaning sapphires is generally straightforward. Warm, soapy water is a safe option, and ultrasonic and steam cleaners are typically suitable for untreated, heat-treated, and lattice diffusion-treated stones. However, fracture-filled or dyed sapphires require gentler cleaning with only a damp cloth.
Symbolism and Metaphysical Beliefs
Throughout history, sapphire has been imbued with profound symbolism. It traditionally represents sincerity, truth, faithfulness, and nobility. Beyond these core values, sapphires have been associated with communication with the divine, attracting wealth, and inspiring peace and harmony. Ancient Greeks and Romans wore sapphires as protection against jealousy and ill wishes. The gem was believed to facilitate communication with oracles, increasing the likelihood of receiving a prophecy. Modern metaphysical beliefs continue to attribute protective and spiritual qualities to sapphire, associating it with illumination and empathy. Alternative September birthstones, lapis lazuli and aventurine, share similar metaphysical properties, offering additional options for those seeking symbolic resonance. Lapis lazuli is linked to illumination, communication, and protection, while aventurine is associated with abundance, empathy, and creativity.
Notable Sapphires
The sources highlight two particularly remarkable sapphires: the Star of Adam and the Star of India. The Star of Adam, discovered in Sri Lanka in 2016, is the world’s largest sapphire, weighing 1404.49 carats and valued at an estimated $100 million (though some estimates reach $175 million). The Star of India, the largest blue star sapphire, boasts 563 carats and is roughly the size of a golf ball. These exceptional stones exemplify the beauty and rarity of sapphire, captivating gem enthusiasts and collectors worldwide.
Care and Cleaning
Sapphires, due to their hardness, are relatively durable gemstones. However, proper care is essential to maintain their brilliance. As previously mentioned, warm, soapy water is a safe cleaning method. Ultrasonic and steam cleaners can be used for most sapphires, but caution should be exercised with fracture-filled or dyed stones, which should only be cleaned with a damp cloth. Avoid harsh chemicals and abrasive materials that could damage the gem’s surface.
Conclusion
Sapphire’s enduring legacy as September’s birthstone is well-deserved. From its ancient origins as a symbol of royalty and protection to its modern-day association with love and commitment, this captivating gem continues to inspire and enchant. Its remarkable hardness, stunning array of colors, and rich symbolism make it a treasured possession for generations to come. Whether chosen for its birthstone significance, its aesthetic beauty, or its metaphysical properties, sapphire remains a timeless and elegant gemstone.
