This article delves into the color of the September birthstone, tracing its geological origins, cultural symbolism, and gemological properties, all grounded in the detailed information provided by authoritative and historical sources.
Sapphires are not just admired for their aesthetic appeal but have also held deep symbolic meaning across cultures and time periods.

This article will explore the color of the September birthstone in depth, covering its geological formation, historical usage, symbolic meanings, and its place in modern jewelry and gemology.
The Color of the September Birthstone
The September birthstone is most commonly associated with a deep blue color, derived from the blue sapphire. This vibrant blue is not an inherent property of the sapphire itself but rather a result of trace elements within the crystal structure. Sapphires are a variety of the mineral corundum, which is inherently colorless. The blue color in sapphires is primarily due to the presence of iron and titanium impurities. Depending on the concentration and distribution of these elements, sapphires can range from a light, sky-blue to a rich, velvety cobalt blue.
The September birthstone color—deep blue—is widely recognized and cherished in gemology. It is also a symbol of calm, clarity, and wisdom, which aligns with the gemstone’s historical and cultural associations.
Geological Formation and Sources
Sapphires, like all corundum varieties, form under high-pressure and high-temperature conditions deep within the Earth’s crust. Over millions of years, aluminum oxide (Al₂O₃) crystallizes into the corundum structure. The presence of trace elements such as iron and titanium introduces the blue coloration. Sapphires can also occur in other colors—pink, yellow, green, purple, and even colorless, depending on the presence of different trace elements—though blue is the most iconic and valuable.
Historically, some of the finest blue sapphires were found in the remote mountainous regions of Kashmir, in northern India. These Kashmiri sapphires are particularly noted for their velvety blue color and fine transparency, making them some of the most sought-after in the world.
Today, the most important sources of high-quality sapphires include:
- Myanmar (Burma) – Known for producing some of the finest blue sapphires with a strong color and excellent clarity.
- Sri Lanka – A major source of sapphires in various colors, including blue, pink, and yellow.
- Thailand and Cambodia – Important centers for sapphire cutting and trade.
- Madagascar – Has become a significant source in recent decades, producing high-quality blue sapphires.
- East Africa and Australia – Provide commercial-grade sapphires.
- Montana, USA – Known for producing sapphires in a range of colors, including blue.
Lab-grown sapphires are also becoming a popular alternative, offering the same chemical and physical properties as natural sapphires but without the ethical and environmental concerns associated with mining.
Historical Significance and Cultural Lore
The September birthstone has a rich and storied history, with the sapphire being revered in many ancient civilizations. The name "sapphire" is derived from the Greek word "sappheiros", meaning "blue" or "precious stone." In ancient times, sapphires were believed to be protective stones, offering their wearers protection from harm and envy.
In ancient Greece and Rome, sapphires were worn by the elite and were thought to promote wisdom and truth. The clergy of the Middle Ages also wore sapphires, as the gemstone was associated with heaven and divine wisdom. In ancient Persia, it was believed that the earth rested on a giant sapphire, which gave the sky its blue color.
Sapphires have also been associated with royalty and nobility. In medieval Europe, sapphires were often set into crown jewels and royal regalia, symbolizing fidelity, purity, and the soul. The gemstone was also believed to have healing properties, with medieval Europeans believing that sapphires could cure plague boils and diseases of the eye. They were also thought to be antidotes to poison.
In ancient Tibet, agate was considered the September birthstone, while in Hindu tradition, zircon—especially the blue variety—was recognized as the September birthstone. These variations highlight how different cultures have interpreted and valued gemstones differently over time.
Despite these variations, the blue sapphire remains the most widely recognized and accepted September birthstone, especially in the modern era. It is also associated with Virgo (August 23 to September 22) and Libra (September 23 to October 23), making it a significant gemstone in zodiac traditions.
Symbolism and Metaphysical Beliefs
Sapphires have long been associated with spiritual and metaphysical properties. In medieval and Renaissance Europe, sapphires were believed to promote inner peace, clarity, and spiritual enlightenment. They were often worn by philosophers, scholars, and religious figures, who believed the gemstone enhanced wisdom and insight.
In modern metaphysical practices, blue sapphires are still considered powerful stones. They are believed to promote emotional balance, mental clarity, and spiritual growth. Some also believe that sapphires can protect the wearer from negative energies and promote good fortune.
The blue color of the September birthstone is particularly symbolic. In many cultures, blue is associated with the sky and the sea, representing serenity, calm, and infinite wisdom. It is also considered a healing color, promoting mental and emotional balance.
In jewelry design, sapphires are often set in rings, pendants, and earrings, making them accessible and versatile gemstones. Their durability—with a Mohs hardness of 9, second only to diamond—makes them ideal for everyday wear.
Sapphire in Jewelry and Modern Celebrations
Sapphires are not only valued for their beauty and symbolism but also for their practicality in jewelry. Their durability and brilliance make them ideal for engagement rings, wedding bands, and anniversary gifts.
Sapphires are traditionally given to celebrate the 5th and 45th wedding anniversaries, while star sapphires—which display a star-like effect due to inclusions aligned along three directions—are the traditional 65th anniversary gift. This makes sapphires a meaningful choice for jewelry that can be passed down through generations.
In the modern era, sapphires have been popularized by celebrities and royalty. For example, the engagement ring of Princess Diana—and later, of Kate Middleton—features a sapphire. This has contributed to the gemstone’s enduring popularity and cultural significance.
Sapphires are also used in high-end jewelry collections and are often featured in designer collections from renowned houses such as Tiffany & Co., Cartier, and Graff. Their versatility in color and cut allows for a wide range of creative and artistic expressions in jewelry design.
Care and Cleaning of Sapphire Jewelry
Given their high hardness and durability, sapphires are relatively easy to care for. However, to maintain their brilliance and longevity, it is important to follow proper cleaning and storage practices.
- Cleaning: Sapphires can be cleaned using warm, soapy water and a soft brush. Avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or the metal setting.
- Ultrasonic cleaners are generally safe for sapphires but should be used with caution, especially if the gemstone has inclusions or fractures, as vibrations can sometimes cause damage.
- Storage: Store sapphires separately from other gemstones to prevent scratching or chipping. A soft pouch or a lined jewelry box is ideal.
Because sapphires are very hard and durable, they are suitable for daily wear and can withstand normal handling and use. However, like all gemstones, they should be handled with care to avoid impact or extreme temperatures.
The September Birthstone in Modern Culture
In modern culture, the September birthstone continues to hold a special place in gemology and jewelry. It is not only a beautiful gemstone but also a symbol of meaning and significance. Its deep blue color is associated with wisdom, truth, and clarity, making it a popular choice for those born in September.
Sapphires are also used in alternative birthstone charts, where iolite and lapis lazuli are sometimes included as September birthstones. However, sapphire remains the most popular and historically significant gemstone for the month.
The popularity of sapphires has also been influenced by scientific advancements and ethical considerations. With the development of lab-grown sapphires, more people can enjoy the beauty and symbolism of sapphires without the ethical and environmental concerns associated with mining natural gemstones.
