The sapphire, a gemstone renowned for its profound blue hue and remarkable durability, stands as the primary birthstone for the month of September. This variety of the mineral corundum has captivated humanity for millennia, serving not only as a cherished adornment but also as a powerful symbol of wisdom, truth, and divine favor. While the classic deep blue is its most iconic color, sapphire encompasses a breathtaking spectrum of hues, each with its own allure. Its status as a September birthstone is rooted in a rich tapestry of history, geology, and lore, making it a subject of enduring fascination for gemstone enthusiasts, jewelry buyers, and students of gemology alike. This article will explore the sapphire's journey from ancient belief to modern gemology, detailing its historical significance, geological origins, gemological properties, symbolic meanings, and practical care.
History and Lore
The history of the sapphire is as deep and layered as the stone itself. The name "sapphire" is derived from the Greek word sappheiros, which means "blue," a direct reference to the color that has defined the gem for centuries. In ancient times, sapphires were considered celestial stones, directly linked to the heavens. The ancient Greeks associated the blue sapphire with Apollo, the god of wisdom and prophecy, believing the stone's color mirrored the sky and provided a connection to the divine.
This association with the divine and the celestial continued through the Middle Ages. Clerics of the period wore sapphires as symbols of Heaven, and the stones were often used in religious vestments and church decorations. The medieval European belief system attributed protective qualities to the sapphire; it was thought to ward off envy and harm. Furthermore, these gems were reputed to possess healing powers, with medieval Europeans believing sapphire could cure ailments such as plague boils and diseases of the eye. It was also considered an antidote to poison, a belief that added to its value and mystique.
The ancient Persians held a particularly dramatic cosmological belief: they thought the earth rested upon a giant sapphire, and the reflection of this colossal stone was what gave the sky its blue color. This belief underscores the profound reverence with which the gem was viewed.
Throughout history, sapphires have adorned royalty and the elite of ancient Greece and Rome, who believed the stones protected their owners from harm and envy. This historical connection to nobility and protection has persisted into contemporary times, where sapphires are still associated with purity, wisdom, and spiritual enlightenment. The September birthstone has traditionally symbolized sincerity, truth, faithfulness, and nobility. Its enduring legacy is evident in famous sapphires like the Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone unearthed in Myanmar (Burma), which serves as a testament to the gem's lasting allure and value.
Geological Formation and Sources
Sapphire is a variety of the mineral corundum, with a chemical composition of aluminum oxide (Al₂O₃). The gem forms under specific geological conditions of high temperature and pressure. The presence of trace elements, such as iron and titanium, within the corundum's crystal lattice is what gives the blue sapphire its characteristic color. The intensity and shade of the blue are determined by the concentrations of these impurities.
While sapphires are found in various locations across the globe, certain regions are particularly renowned for their production of high-quality gems. Historical sources indicate that Myanmar (formerly Burma) has been a significant source for centuries, as evidenced by the origin of the Rockefeller Sapphire. This region is celebrated for producing sapphires with a rich, vibrant blue color, often considered the benchmark for the gem.
Other notable mining locations for sapphires include Sri Lanka, which is famous for its "padparadscha" sapphires—a rare and prized pink-orange variety—and for producing a wide range of other colored sapphires. Madagascar has also emerged as a major source in recent decades, contributing a substantial volume of sapphires to the global market. Thailand and Australia are other important commercial sources for this gemstone. The geological diversity of these regions contributes to the wide array of colors and qualities found in sapphires available today.
Gemological Properties
The sapphire's physical and optical properties are key to its durability and beauty, making it an exceptional choice for jewelry. As a member of the corundum family, it shares many characteristics with ruby, differing primarily in color.
Hardness and Durability: One of the most significant attributes of sapphire is its exceptional hardness. On the Mohs scale of mineral hardness, sapphire scores a 9. This places it just below diamond (which scores 10) and makes it one of the hardest naturally occurring substances. This remarkable hardness contributes to its excellent durability, making it highly resistant to scratching and abrasion. This property is why sapphire is considered ideal for everyday wear jewelry, such as rings, necklaces, and earrings, and is a top choice for engagement rings and heirloom pieces that are meant to last for generations.
Color and Varieties: While the classic deep royal blue is the most iconic and sought-after color for the September birthstone, sapphires actually occur in nearly every color of the rainbow, with one exception. Sapphires of all colors except red are classified as sapphires; the red variety of corundum is called ruby. This broad color range offers immense versatility for personal expression and jewelry design.
- Classic Blue Sapphire: The traditional and most popular color, often described as a rich royal blue, symbolizing depth, truth, and serenity.
- Padparadscha Sapphire: A rare and highly prized variety that exhibits a delicate pink-orange hue, reminiscent of a sunset. Its name is derived from the Sinhalese for "lotus blossom."
- Fancy Sapphires: This term encompasses sapphires in colors such as yellow, green, purple, pink, and even color-changing varieties. These stones provide a vibrant alternative to the classic blue and are increasingly popular in modern jewelry.
Clarity and Cut: Sapphires are typically evaluated for their clarity, with inclusions being common. However, the value of a sapphire is not solely determined by the absence of inclusions; the stone's color and overall appearance are paramount. Skilled gem cutters shape sapphires into various cuts to maximize their color and brilliance. The rectangular step cut, as seen in the Rockefeller Sapphire, is one classic example, but round, oval, cushion, and emerald cuts are also widely used.
Chemical Composition: As a variety of corundum, sapphire's chemical formula is Al₂O₃. Its crystalline structure is trigonal, and it has a specific gravity that typically ranges from 3.95 to 4.03. These properties, combined with its hardness, define its identity in the mineral world.

Symbolism and Metaphysical Beliefs
The sapphire's symbolism is deeply intertwined with its historical and cultural significance. Across different eras and cultures, the gem has been attributed with meanings that reflect its perceived qualities of wisdom, purity, and protection.
The primary symbolic associations of the sapphire, as supported by historical accounts, are truth, loyalty, and integrity. In ancient times, it was believed to protect wearers from envy and harm, a belief held by the elite of ancient Greece and Rome. This protective quality made it a favorite among royalty and clergy, who saw it as a symbol of divine favor and wisdom.
In medieval Europe, the sapphire's association with the heavens led to its use as a symbol of spiritual insight and purity. Clerics wore it to symbolize Heaven, and it was believed to bring spiritual enlightenment. The stone was also thought to have healing properties, with medieval Europeans believing it could cure diseases of the eye and act as an antidote to poison.
The Persian belief that the earth rested on a giant sapphire, which colored the sky blue, is a powerful example of the stone's metaphysical significance, linking it directly to the creation and stability of the world.
Today, the September birthstone continues to resonate with these ancient meanings. Sapphires are still viewed as protective stones and are frequently chosen for engagement rings and other meaningful jewelry due to their associations with fidelity, sincerity, and nobility. For those born on September 10th, the sapphire is more than a beautiful jewel; it is a symbol of wisdom, virtue, and nobility, a legacy that has been cherished for centuries.
Care and Cleaning
Given its exceptional hardness and durability, sapphire is relatively easy to care for, making it a practical choice for jewelry that is worn regularly. However, proper care will ensure the gemstone retains its beauty and brilliance for a lifetime.
Daily Wear: Sapphire's 9 Mohs hardness makes it highly resistant to scratching from everyday materials like dust and sand (which are primarily quartz, hardness 7). This is why it is an excellent choice for rings, which are subject to frequent contact. However, it is still important to avoid exposing sapphire jewelry to sharp blows or hard impacts, as this could potentially cause chipping or fracture, especially at the girdle or facet junctions.
Cleaning: The safest way to clean sapphire jewelry is with warm water, a mild soap, and a soft brush. A soft toothbrush can be used to gently scrub away any dirt or oils that may have accumulated behind the stone or in the setting. After cleaning, the piece should be rinsed thoroughly with clean water and dried with a soft, lint-free cloth.
It is advisable to avoid using harsh chemicals or ultrasonic cleaners, particularly if the sapphire is set in a piece of jewelry that also contains other, more fragile gemstones or if the setting is delicate. While sapphire itself is resistant to most chemicals, the settings (often made of gold or platinum) and any accompanying stones could be damaged. For thorough cleaning or if the jewelry has not been cleaned in a long time, it is best to take it to a professional jeweler who can check the security of the setting and clean the piece safely.
Storage: When not being worn, sapphire jewelry should be stored separately from other pieces to prevent scratching. A soft-lined jewelry box or a dedicated compartment is ideal. This simple practice will protect both the sapphire and any other jewelry it is stored with.
