Its exceptional hardness, ranking 9 on the Mohs scale, makes it an ideal gemstone for daily wear in jewelry, from engagement rings to heirloom pieces. As we explore the multifaceted nature of sapphire, we uncover the reasons behind its revered status across cultures and epochs.
History and Lore
Sapphire has been cherished for thousands of years, with its lore deeply intertwined with royalty, religion, and protection. The term "sapphire" is derived from the Greek word sappheiros, and blue sapphire is one of the most popular colored stones in history.
Ancient Beliefs and Royalty
In ancient Greece and Rome, the elite believed that blue sapphires protected their owners from harm and envy. This belief in its protective power extended to the Middle Ages, where clerics wore sapphires because they symbolized Heaven. The ancient Persians held a grander cosmological belief, thinking that the earth rested on a giant sapphire, which in turn made the sky blue.
Beyond protection, sapphire has long been associated with sincerity, truth, faithfulness, and nobility. For countless centuries, it has adorned royalty and the robes of the clergy, serving as a visual emblem of high status and moral virtue.
Healing Powers and Folklore
The September birthstone was also reputed to have healing powers. Medieval Europeans believed that sapphire could cure plague boils and diseases of the eye. Furthermore, it was thought to be an effective antidote to poison. These attributes contributed to its value not just as an ornament but as a practical amulet for health and safety.
The Path to a Modern Birthstone
The tradition of birthstones is largely based on biblical references, specifically the twelve gemstones on Aaron's breastplate and the foundation stones of the New Jerusalem. While modern birthstone lists have evolved, sapphire has remained a consistent and central gem for September. Its historical significance and enduring beauty ensured its place on contemporary lists, which often include it as the primary birthstone, with alternatives like lapis lazuli and jasper also associated with the month through various zodiac and astrological systems.
Geological Formation and Sources
Sapphire is a variety of the mineral corundum, an aluminum oxide (Al₂O₃). Its formation requires specific geological conditions involving high pressure and temperature, typically in metamorphic rocks like schist and gneiss, or in certain igneous rocks such as basalt.
Notable Mining Locations
While sapphire deposits are found worldwide, certain regions are renowned for producing the highest quality stones. The famous Rockefeller Sapphire, a 62.02-carat rectangular step-cut stone, was unearthed in Myanmar (Burma), a region historically known for producing some of the world's most exquisite blue sapphires. Other significant sources include Sri Lanka, Kashmir, and Australia, though the specific locations mentioned in the provided sources are limited to Myanmar. The geographic origin of a sapphire can significantly influence its color, clarity, and overall value, with Burmese sapphires often commanding premium prices in the market.
Gemological Properties
Sapphire's value and appeal are rooted in its exceptional physical and optical characteristics. Its durability and color range make it a versatile gemstone for jewelry.
Color and Variety
While sapphires are most commonly associated with blue, they are available in a rainbow of other colors, including pink, yellow, green, and even colorless varieties. Any corundum that is not red is classified as a sapphire; red corundum is designated as ruby. The most iconic sapphire color is blue, which can range from light, pastel blues to deep, intense navy hues. The value of a blue sapphire is determined by a combination of factors, with color being paramount. The most sought-after sapphires exhibit a rich, uniform color with minimal inclusions.
Hardness and Durability
A key property that makes sapphire ideal for jewelry is its remarkable hardness. On the Mohs scale of mineral hardness, sapphire scores a 9, placing it just below diamond (10). This exceptional hardness means sapphire is resistant to scratching and abrasion, making it an excellent choice for pieces intended for daily wear, such as engagement rings, bracelets, and other frequently used jewelry. This durability, combined with its brilliant color, ensures that sapphire jewelry can be cherished for generations.
Clarity, Cut, and Carat
The value of a sapphire is also influenced by its clarity, cut, and carat weight. Inclusions are common in natural sapphires, but stones with minimal visible inclusions are more valuable. The cut of a sapphire is designed to maximize its color and brilliance, with popular cuts including oval, round, and cushion. As with all gemstones, larger carat weights generally command higher prices, especially for stones with desirable color and clarity.
The following table summarizes the key gemological properties of sapphire as described in the provided sources:

|---|---|
| Mineral Family | Corundum |
| Chemical Formula | Al₂O₃ (Aluminum Oxide) |
| Hardness (Mohs Scale) | 9 |
| Typical Colors | Blue (most famous), also pink, yellow, green, colorless |

Symbolism and Metaphysical Beliefs
Beyond its physical properties, sapphire is imbued with deep symbolic meaning. These associations have evolved over centuries, from ancient protection charms to modern symbols of love and commitment.
Historical Symbolism
As previously noted, sapphire has been linked to wisdom, virtue, and good fortune. Its association with sincerity and truth made it a favored stone for royalty and clergy, who needed to project integrity. The belief in its protective power against envy and harm was widespread in the ancient world.
Modern Interpretations
In contemporary culture, sapphire has become a powerful symbol of fidelity and enduring love. This is particularly evident in its use for engagement rings, where it offers a unique and meaningful alternative to traditional diamonds. The deep blue of a sapphire provides a stunning contrast to white diamonds and can be a distinctive choice for those looking to stand out. Sapphire engagement rings are often paired with diamonds to enhance their brilliance and create a striking effect, symbolizing lasting commitment.
Metaphysical Claims
While the provided sources focus on historical and cultural beliefs, they also touch on metaphysical claims. Some modern interpretations suggest that sapphire can aid in focus and mental clarity, though this is not a formally recognized gemological property. It is important to distinguish between established historical lore and contemporary spiritual beliefs, which are not scientifically verified.
Care and Cleaning
The exceptional hardness of sapphire makes it relatively easy to care for. However, proper maintenance is essential to preserve its beauty and longevity.
Daily Wear and Storage
Due to its hardness of 9 on the Mohs scale, sapphire is resistant to scratching from most other materials. This makes it suitable for daily wear in rings, earrings, and pendants. When not worn, sapphire jewelry should be stored separately from other pieces to prevent accidental scratches, though the risk is minimal given its hardness.
Cleaning Instructions
Sapphire can be cleaned safely using warm water, mild soap, and a soft brush. Ultrasonic cleaners are generally safe for sapphires, but caution is advised if the stone has been fracture-filled or if the jewelry setting is delicate. Steam cleaning is also typically safe for untreated sapphires. It is always recommended to consult with a professional jeweler if there is any doubt about the treatment or setting of the gemstone.
Considerations for Jewelry Settings
While the gemstone itself is durable, the jewelry setting requires attention. Prong settings, while classic, can be vulnerable to snagging. Regular inspection of the setting by a jeweler is advised to ensure the sapphire remains secure, especially for pieces like bracelets and rings that are subject to daily wear.
Conclusion
Sapphire, the celebrated birthstone of September, is a gem of unparalleled beauty and significance. Its rich history, marked by associations with royalty, protection, and wisdom, is matched by its remarkable physical properties, including exceptional hardness and a captivating color range. From the ancient belief that it could ward off envy to its modern role as a symbol of fidelity in engagement rings, sapphire has continuously captivated humanity.
Whether valued for its stunning blue hues, its durability for everyday jewelry, or its deep symbolic meanings, sapphire remains a timeless and cherished gemstone. For those born in September or anyone who appreciates fine gemology, sapphire offers a connection to both nature's artistry and a rich tapestry of cultural heritage. Its enduring appeal ensures it will continue to inspire and adorn for generations to come.
