Historically, it has been a symbol of royalty and power, often adorning the crowns and jewelry of monarchs. In addition to its physical attributes, sapphire carries a rich tapestry of metaphysical and cultural meanings, making it a deeply meaningful gemstone for those born in September and those who cherish its symbolism.
This article delves into the geological formation of sapphire, its role in September birthstone lore, and its significance in zodiac signs like Virgo and Libra. We also examine the gemstone’s properties, its uses in jewelry, and the care it requires to maintain its beauty over time.
History and Lore
Sapphire has been admired for centuries, often associated with wisdom and protection. The gemstone has been found in ancient royal jewelry, including pieces from India, Egypt, and the Roman Empire. In medieval Europe, sapphire was believed to offer protection from harm and to symbolize loyalty and trust. The gemstone was also considered a symbol of the heavens, with its deep blue color representing the sky and divine wisdom.
In the context of zodiac signs, sapphire is closely linked to Virgo and Libra, the two zodiac signs that span the month of September. For Virgo, sapphire is a zodiac birthstone that enhances mental clarity and encourages attention to detail. It is also believed to promote loyalty and sincerity, qualities that align with the Virgo personality.
The September birthstone is also connected to the zodiac animal of the Rooster, which represents alertness, precision, and organization. These traits complement the analytical and detail-oriented nature of sapphire itself.
While sapphire is the primary birthstone for September, Lapis Lazuli is sometimes mentioned as an alternative. Lapis Lazuli, another deep blue gemstone, shares a similar color but differs in composition and symbolism. It is often associated with Libra and is believed to enhance communication and inner harmony.
Geological Formation and Sources
Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes sapphire from other corundum varieties is the trace elements that give it its color. The deep blue hue of sapphire is primarily due to the presence of iron and titanium. Other trace elements can result in sapphires that range in color from pink to green to yellow.
Sapphire is formed under high-pressure and high-temperature conditions deep within the Earth's crust. It is typically found in metamorphic rocks, such as gneiss and schist, and in igneous rocks like basalt. The gemstone is mined in several countries around the world, with notable sources including:
- Sri Lanka: Known for producing some of the finest blue sapphires.
- Myanmar (Burma): Famous for its "pigeon’s blood" sapphires, which have an intense red or purplish hue.
- Australia: A major producer of sapphires, particularly in the state of New South Wales.
- Madagascar: A growing source of high-quality sapphires in recent decades.
- India, Thailand, and the United States: Also produce sapphires, though in smaller quantities compared to the leading sources.
Sapphire’s durability and hardness make it a popular choice for jewelry. On the Mohs scale of mineral hardness, sapphire ranks at 9, second only to diamond. This high hardness means that sapphires are resistant to scratches and are suitable for everyday wear.

For Libra, sapphire is associated with balance and harmony. It is believed to help Libra individuals maintain a sense of equilibrium in their lives and relationships. Sapphires are also associated with the star Spica, which is believed to offer guidance and inspiration to those born in September.
Care and Cleaning
Due to its high hardness and durability, sapphire is relatively easy to care for. However, to maintain its beauty and luster over time, it is important to follow some basic care and cleaning guidelines.
Sapphires can be cleaned using a mild soap solution and a soft brush. It is important to avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or its setting. Ultrasonic cleaners are generally safe for sapphire, but it is important to consult with a jeweler to ensure that the stone is free of internal fractures or other vulnerabilities that could be affected by the ultrasonic process.
When storing sapphire jewelry, it is best to keep the pieces in a soft pouch or a lined jewelry box to prevent scratches. Sapphires can scratch other gemstones, so it is advisable to store them separately or in a padded compartment.
When wearing sapphire jewelry, it is important to avoid exposing it to extreme temperatures or sudden temperature changes, as this can cause the stone or its setting to crack. Sapphires are also sensitive to certain chemicals, including bleach and ammonia, so it is best to remove sapphire jewelry before using such substances.
Regular inspections by a professional jeweler can help to ensure that the gemstone remains secure in its setting and that the jewelry is in good condition. This is especially important for rings and other pieces that are worn frequently.
