For millennia, the sapphire has captivated humanity with its rich hues and enduring beauty. As the birthstone for September, this gemstone embodies sincerity, truth, and faithfulness, qualities that have resonated across cultures and throughout history. While most readily recognized in its classic deep blue form, the sapphire reveals a surprising spectrum of colors, making it a versatile and deeply personal gem. This article will delve into the history, geological origins, gemological properties, symbolism, and care of the September birthstone, the sapphire.
History and Lore
The sapphire’s story is interwoven with the narratives of ancient civilizations. In ancient Greece and Rome, sapphire was believed to offer protection from harm and envy. The elite of these societies adorned themselves with blue sapphires, seeking to ward off negative energies and ensure good fortune. Similarly, medieval Europeans attributed healing powers to the stone, believing it could cure plague boils and alleviate eye ailments, even serving as an antidote to poison. Ancient Persians held a particularly striking belief – that the earth rested upon a giant sapphire, which was responsible for the sky’s blue color.
Clerics of the Middle Ages valued sapphires for their symbolic connection to Heaven, often incorporating them into their robes. This association with royalty and the divine continued for centuries, solidifying the sapphire’s status as a gem of nobility and spiritual significance. In 1912, the American National Association of Jewelers officially recognized blue sapphire as the birthstone for September, a designation that further cemented its place in modern tradition. It is also traditionally used to commemorate the 5th, 23rd, and 45th wedding anniversaries, with the rare star sapphire reserved for the 65th anniversary.
Geological Formation and Sources
Sapphires belong to the corundum family, a crystalline form of aluminum oxide. The presence of trace elements within the corundum structure dictates the gemstone’s color. Titanium and iron are responsible for the most prized blue hues, while other elements create the “fancy colored” sapphires – pink, purple, yellow, green, and even colorless varieties. When chromium is present in high concentrations, the resulting gem is classified as a ruby, rather than a sapphire, though technically a ruby is a red sapphire.
The formation of sapphires is a complex geological process, typically occurring in metamorphic and igneous rocks. These gems are often found in alluvial deposits, having been eroded from their original source and carried by water. While specific mining locations are not detailed in the provided sources, the gem’s widespread appeal suggests global sources.
Gemological Properties
Sapphires are renowned for their exceptional durability, ranking nine on the Mohs scale of hardness – second only to diamond. This hardness makes them exceptionally well-suited for everyday wear, whether set in an engagement ring or delicate earrings. Sapphires are composed of aluminum oxide, and their color is evaluated based on hue, tone, and saturation.
The term “sapphire” generally refers to the blue variety of corundum. However, any corundum gem that isn’t red is considered a sapphire, and will be explicitly described by its color – for example, “purple sapphire” or “green sapphire.” Some sapphires exhibit a fascinating optical phenomenon called asterism, displaying a star-like appearance due to tiny needle-like inclusions within the stone. This effect is most prominent in cabochon cuts, and can manifest with six, twelve, or even a cat’s-eye effect. A high-quality 1-carat blue sapphire can cost between $3000-$5000, though prices fluctuate daily.
A summary of key gemological properties is presented below:
| Property | Description |
|---|---|
| Mineral | Corundum (Aluminum Oxide) |
| Hardness (Mohs) | 9 |
| Color | Primarily Blue, but occurs in a rainbow of colors |
| Luster | Vitreous (glass-like) |
| Crystal System | Trigonal |
| Refractive Index | Not specified in sources |
Symbolism and Metaphysical Beliefs
Throughout history, sapphires have been imbued with profound symbolic meaning. They are considered a protective gemstone, shielding the wearer from both physical harm and negative intentions. Blue sapphires, in particular, are associated with spirituality and were often worn by priests. The gem is traditionally linked to sincerity, truth, faithfulness, and nobility, reflecting its long-standing association with royalty and the clergy. Sapphires are also believed to possess medicinal properties, though these claims are rooted in historical beliefs rather than scientific evidence.
The color of a sapphire also contributes to its symbolism. While blue sapphires represent serenity and wisdom, fancy colored sapphires offer unique interpretations. Pink sapphires evoke romance, yellow sapphires radiate joy, and green sapphires embody nature’s vitality.
Care and Cleaning
Sapphires are a durable gemstone, but proper care is essential to maintain their brilliance. Their high hardness makes them resistant to scratching, but they can still be chipped or damaged by sharp blows. Regular cleaning with warm, soapy water and a soft brush is recommended to remove dirt and oils. Avoid harsh chemicals or abrasive cleaners, as these can damage the stone’s surface. Ultrasonic cleaners are generally safe for untreated sapphires, but caution should be exercised with stones that have been fracture-filled or heat-treated.
Some sapphires undergo common treatments to enhance their color or clarity. These treatments do not necessarily diminish the gem’s beauty, but it’s important to be aware of them when cleaning and caring for the stone.
Conclusion
The sapphire, September’s captivating birthstone, is a gem of enduring beauty and rich symbolism. From its ancient origins as a protector against harm to its modern status as a symbol of fidelity and truth, the sapphire has held a special place in human culture for millennia. Its exceptional durability, combined with its stunning array of colors, makes it a cherished gemstone for jewelry and a meaningful gift for those born in September. The sapphire’s legacy continues to shine, representing not only a beautiful adornment but also a timeless connection to history, lore, and the enduring power of nature’s artistry.
