The sapphire, a gemstone of deep blue brilliance and timeless elegance, is the traditional birthstone for the month of September. Its name, derived from the Greek word sappheiros, is synonymous with the celestial hue that has captivated humanity for millennia. While the sapphire is celebrated for its classic blue variety, it is important to note that the gemstone encompasses a full spectrum of colors, with the notable exception of red, which is classified as ruby. For those born on September 6th, the sapphire holds an even more profound significance, believed to enhance the innate traits of truth, wisdom, and emotional healing. This article explores the rich history, geological origins, gemological properties, and enduring symbolism of this remarkable gemstone, drawing exclusively from established gemological and historical records.
History and Lore
The sapphire's history is as deep and layered as its most prized colors. For countless centuries, this gem has adorned royalty and the clergy, serving as a powerful symbol of virtue and divine favor. The elite of ancient Greece and Rome believed that blue sapphires could protect their owners from harm and envy. The Roman naturalist Pliny the Elder, in his seminal work Natural History, wrote of sapphires as gems that could ward off poison and disease, highlighting their perceived medicinal properties. This ancient belief in the sapphire's protective power extended to a spiritual realm, with clerics of the Middle Ages wearing sapphires as a symbol of Heaven, associating the gem's blue color with the sky and divine connection.
Ancient Persians held a particularly poetic belief about the sapphire's origin, suggesting that the earth itself rested upon a giant sapphire, which in turn gave the sky its blue color. This celestial association has persisted through the ages. During the Middle Ages, sapphires were not only symbols of heaven but were also believed to have practical healing powers. Medieval Europeans attributed to the sapphire the ability to cure plague boils and diseases of the eye, and it was thought to be an effective antidote to poison.
The journey of the sapphire to its modern status as a birthstone is a more recent development. The recognition of sapphire as the birthstone for September originated in the United States. The American National Association of Jewelers, now known as Jewelers of America, undertook an initiative to create a standardized list of birthstones. Their chart, which assigned sapphire to the month of September, established a tradition that has prevailed over the years, both within America and internationally. This standardization helped solidify the sapphire's position in contemporary culture, linking its ancient symbolism to a modern tradition of personal adornment.
Geological Formation and Sources
Sapphires are formed under extreme geological conditions, making their discovery a testament to both natural processes and human endeavor. Belonging to the corundum species of minerals, sapphires are composed of aluminum oxide (Al₂O₃). They typically form in prismatic or tabular crystals with a distinct hexagonal cross-section. These crystals develop in metamorphic rocks, such as gneiss and schist, or in alluvial deposits where they have been eroded from their original host rock and carried by water.
The sources of sapphire are scattered across the globe, with several regions renowned for producing stones of exceptional quality. One of the most famous sources is Myanmar (formerly Burma), which has yielded some of the world's most celebrated sapphires. The Rockefeller Sapphire, a notable 62.02-carat rectangular step-cut stone, was unearthed in Myanmar, underscoring the country's historical importance in the gem trade. Other significant sources include Sri Lanka (Ceylon), which is famed for its light to medium blue sapphires, and Kashmir, a region that produced velvety blue sapphires in the late 19th and early 20th centuries. Madagascar, Australia, Thailand, and Cambodia are also important modern sources, each contributing to the global supply of this coveted gem.
Gemological Properties
The sapphire is prized not only for its color but also for its remarkable physical durability, which makes it an excellent choice for all types of jewelry, especially rings and bracelets that are subject to daily wear.
Chemical Composition and Crystal Structure: As a member of the corundum family, sapphire's chemical formula is aluminum oxide (Al₂O₃). Trace impurities of elements such as iron, titanium, and chromium are responsible for its various colors. For example, iron and titanium produce the classic blue hue, while chromium can create a pink or red color (which would then be classified as a ruby). Sapphires crystallize in the hexagonal crystal system, often forming as prismatic or tabular crystals.
Hardness and Durability: On the Mohs scale of mineral hardness, sapphire ranks a formidable 9. This makes it the third-hardest natural mineral, surpassed only by diamond (10) and moissanite (9.25). This exceptional hardness means that sapphire is highly resistant to scratching and abrasion, a key reason for its enduring popularity in fine jewelry. Its durability is second only to diamond among popular colored gemstones.
Color: While "sapphire" is most commonly associated with blue, the gemstone occurs in a rainbow of other colors, known as "fancy sapphires." These can include yellow, green, orange, pink, and purple. The only color excluded from the sapphire designation is red, which is reserved for ruby. The most valued blue sapphires typically exhibit a vivid to deep blue with a slight hint of violet, but the ideal color can vary based on market trends and personal preference.
Clarity and Inclusions: Natural sapphires often contain inclusions, which are internal features that can be viewed under magnification. These inclusions are not necessarily seen as flaws; they can provide evidence of a gem's natural origin. Some sapphires, particularly those from Kashmir, may exhibit a "silky" inclusion pattern caused by fine rutile needles, which can create a soft, velvety appearance. While eye-clean sapphires are highly valued, certain types of inclusions are accepted and even sought after in the gem trade.
Cut and Carat Weight: Sapphires are cut into a variety of shapes, including oval, cushion, round, and pear cuts, to maximize their color and brilliance. The cut must be carefully executed to showcase the stone's best attributes while minimizing any undesirable color zoning. Sapphires are available in a wide range of carat weights, from small accent stones to large, museum-quality specimens weighing hundreds of carats.

Symbolism and Metaphysical Beliefs
The sapphire's symbolism is multifaceted, encompassing themes of wisdom, purity, protection, and love. These associations have been built over centuries and are deeply ingrained in various cultures.
Wisdom and Clarity: One of the most prominent symbolic associations of the sapphire is wisdom. In ancient times, sapphires were believed to promote intellectual clarity and insight. Wearing a sapphire was thought to help individuals make thoughtful and informed decisions, making it a gemstone of great value to scholars, philosophers, and leaders. This association with wisdom is particularly meaningful for those born in September, as it is believed to guide them through the complexities of life.
Purity and Virtue: Sapphires have long been linked to purity and moral integrity. In the Middle Ages, religious figures such as clergy and bishops wore sapphires as a symbol of their commitment to purity and virtue. This association continues to be relevant today, with the sapphire often seen as a symbol of sincerity and ethical living. The September birthstone has traditionally symbolized sincerity, truth, faithfulness, and nobility.
Protection and Loyalty: The sapphire is also regarded as a protective stone. In ancient Greece and Rome, sapphires were worn to ward off harm and envy. They were believed to offer spiritual and physical protection to their wearers. This protective quality extends to a belief in good fortune, with sapphires considered talismans against negative energies, evil spirits, and curses. Furthermore, sapphires are associated with love and commitment, symbolizing fidelity and loyalty, which is why they are a popular choice for engagement rings and anniversary gifts.
Spiritual Enlightenment: In some cultures, sapphires are linked to spiritual enlightenment and inner peace. Particularly in Buddhist culture, the blue color of sapphires is reminiscent of the vast sky and is associated with deep meditation and spiritual growth. This connection to the heavens reinforces the gem's ancient reputation as a stone of divine favor and higher consciousness.
Care and Cleaning
Given its exceptional hardness, the sapphire is a relatively easy gemstone to care for, making it suitable for everyday jewelry. However, proper maintenance is essential to preserve its beauty and structural integrity over time.
Daily Cleaning: Sapphires can be safely cleaned using warm water, a mild soap, and a soft brush. Gently scrubbing the stone and its setting will remove accumulated oils, dirt, and lotions. It is important to avoid harsh chemicals, such as bleach or ammonia, which can damage the metal settings or, in some cases, treat any surface fractures. Ultrasonic cleaners are generally safe for sapphires, but they should be used with caution if the stone has significant inclusions or fractures, as the vibrations could potentially cause damage. Steam cleaning is also an option but should be avoided for sapphires that have been fracture-filled or treated with heat.
Storage: When not being worn, sapphire jewelry should be stored separately from other pieces to prevent scratches. While sapphire is hard enough to scratch most other gemstones, it can be scratched by diamond and, on rare occasions, by other sapphires. A soft-lined jewelry box or individual pouches are ideal for storage.
Professional Maintenance: While regular cleaning is sufficient for most sapphire jewelry, it is recommended to have the gemstone inspected by a professional jeweler or gemologist periodically. A jeweler can check for signs of wear, ensure that the setting remains secure, and provide professional cleaning and polishing services if needed. This is particularly important for rings and bracelets that are worn daily, as the settings can become loose over time.
