For those born in September, the month is graced by one of the most iconic and revered gemstones in the world: the sapphire. Sapphires have long been associated with nobility, wisdom, and protection, and their deep blue color symbolizes the vastness of the sky and the ocean. As the birthstone for September, sapphires have held a distinguished place in history, mythology, and jewelry for centuries. Yet, the September birthstone is not limited to sapphire alone. Alternative stones such as lapis lazuli and aventurine also offer rich cultural and symbolic significance, making the birthstone tradition of September a fascinating study in both gemology and cultural history.
This article will explore the September birthstone in depth, beginning with the sapphire’s historical and symbolic legacy, followed by its geological and gemological properties. We will then examine the alternative September birthstones—lapis lazuli and aventurine—detailing their own unique histories, uses, and meanings. The article will also provide practical guidance on caring for these gemstones and understanding their value in the market.
History and Symbolism of the Sapphire
Sapphires have captivated humans for millennia, not only for their beauty but also for the symbolic and spiritual meanings they carry. The name "sapphire" is derived from the Greek word sappheiros, meaning "blue." While the blue variety of corundum is the most well-known, sapphires can be found in a wide range of colors, including pink, yellow, green, and even colorless—though these are often referred to by different names such as "padparadscha" for the rare pink-orange sapphires.
The symbolic power of sapphires is deeply rooted in ancient traditions. In ancient Greece and Rome, sapphires were believed to offer protection against harm and envy. During the Middle Ages, clergymen wore sapphires to symbolize heaven, and the gemstone was associated with purity and divine wisdom. Ancient Persians even believed that the earth rested on a massive sapphire, which reflected blue light and gave the sky its color.
Sapphires have also played a role in the healing arts. Medieval Europeans believed that sapphires could cure plague boils and eye diseases, and they were thought to serve as an antidote to poison. These beliefs highlight the gemstone’s dual role as both a protective and therapeutic stone.
In modern times, sapphires continue to be associated with sincerity, truth, and faithfulness. The gemstone has long been a favorite among royalty and nobility, appearing in crowns, royal jewels, and heirlooms. In fact, sapphires have been used in royal weddings and engagements, most famously in the engagement ring of the late Princess Diana of Wales, which was later passed on to Kate Middleton, the current Duchess of Cambridge.
Geological Formation and Sources of Sapphire
Sapphires are a form of corundum, a mineral composed of aluminum oxide (Al₂O₃). What distinguishes sapphires from other corundum varieties is their color, which is caused by trace elements. The most common and valuable sapphires are blue, which are colored by the presence of iron and titanium. Other trace elements such as chromium produce pink or red sapphires, while iron and magnesium give rise to yellow or green sapphires.
The formation of sapphires occurs under high-pressure, high-temperature conditions in igneous and metamorphic rock environments. Sapphires are typically found in alluvial deposits, where they have been eroded from their original rock and transported by water. This process allows the gemstones to be found in sediment, often mixed with other heavy minerals.
Some of the most renowned sapphire sources include:
- Afghanistan and Pakistan: These regions have been important sapphire sources since ancient times, and their sapphires are known for their deep blue color.
- Sri Lanka: Known as the "Ceylon sapphire," Sri Lankan sapphires are prized for their vibrant blue and yellow hues.
- Madagascar and Tanzania: These African countries have become major producers of high-quality sapphires in recent decades.
- Australia: Australia is the largest producer of sapphires by volume, though they are generally of lower color intensity.
The hardness of sapphires, rated at 9 on the Mohs scale, makes them highly durable and suitable for everyday wear in jewelry. Their refractive index and excellent luster further contribute to their desirability as gemstones.
Gemological Properties of the Sapphire
Sapphires are among the hardest and most durable gemstones, second only to diamonds on the Mohs scale. With a hardness of 9, they are resistant to scratches and abrasions, making them ideal for use in rings and other frequently worn jewelry. The gemstone’s chemical composition is Al₂O₃, and it is typically free of inclusions, although some sapphires may contain small gas bubbles or other mineral inclusions that can affect their clarity.
Sapphires are typically cut into brilliant or modified brilliant shapes to maximize their fire and brilliance, although they can also be cut as cabochons, especially when they contain asterism (star sapphires). The most valuable sapphires are those with a rich, intense blue color known as the "cornflower blue." This color is achieved through precise heating and cooling processes, and natural sapphires are often heat-treated to enhance their color and clarity.
The carat weight of sapphires can vary widely, from small gemstones used in earrings and pendants to large stones weighing many carats. The price of a sapphire is influenced by several factors, including color, clarity, cut, and origin. Large, high-quality sapphires can command extremely high prices, especially if they come from prestigious sources like Burma (Myanmar) or Kashmir.
Alternative September Birthstones
While sapphires are the most widely recognized September birthstone, the tradition of birthstones is not rigidly defined and has evolved over time. In some historical and cultural contexts, other gemstones have been associated with September. Two notable alternatives are lapis lazuli and aventurine, both of which carry their own unique histories and symbolic meanings.
Lapis Lazuli
Lapis lazuli is a metamorphic rock composed primarily of lazurite, a deep blue mineral. It also contains smaller amounts of pyrite and calcite, which create a striking visual contrast. The gemstone has been prized for thousands of years, particularly in ancient Egypt and Mesopotamia, where it was used in jewelry, amulets, and ceremonial objects. Pharaohs and high priests often wore lapis lazuli as a symbol of power and divine favor.
The spiritual properties of lapis lazuli are closely tied to intuition and truth. It is associated with the third eye chakra and is believed to enhance psychic abilities and promote inner clarity. In modern times, lapis lazuli is still used in jewelry and is appreciated for its vibrant blue color and subtle golden flecks.
Lapis lazuli is primarily mined in Afghanistan, where it has been extracted for over 7,000 years. Other sources include Russia, Chile, and the United States. The gemstone is relatively soft, with a hardness of 5 to 6 on the Mohs scale, and it requires careful handling to avoid scratches and damage.
Aventurine
Aventurine is a type of quartz that is characterized by its sparkling inclusions, known as aventurescence. The gemstone is most commonly green, but it can also be found in yellow, orange, and blue varieties. Aventurine is associated with the zodiac sign Virgo and is believed to promote abundance, creativity, and emotional balance.
In ancient times, aventurine was believed to be a stone of protection and was used in amulets and talismans. It is also associated with the kingdom of the gods, suggesting a spiritual and divine connection. Aventurine is a popular choice for jewelry, especially in the form of beads and cabochons, due to its soft, inviting appearance.
Aventurine is relatively easy to work with and is found in several countries, including India, Brazil, and the United States. It has a hardness of 6.5 to 7 on the Mohs scale, making it suitable for everyday wear, though it should still be handled with care to avoid scratches and chipping.
Metaphysical and Cultural Significance of September Birthstones
Beyond their physical and geological properties, September birthstones are also rich in metaphysical and cultural significance. Sapphires, lapis lazuli, and aventurine are all associated with different energies, meanings, and uses in various traditions and belief systems.
Sapphires are often regarded as stones of wisdom and clarity. They are believed to enhance mental focus, promote truth, and protect the wearer from negative influences. In some cultures, sapphires are also associated with royalty and divine favor, making them symbols of power and prestige.
Lapis lazuli is often referred to as a stone of the mind and the heart. It is believed to stimulate intellectual activity, promote self-awareness, and enhance communication. Its golden flecks are said to represent the spark of the divine, and the gemstone is often used in meditation and spiritual practices.
Aventurine is associated with abundance and opportunity. It is believed to attract wealth, success, and good fortune, making it a popular stone for those seeking to improve their circumstances. Aventurine is also thought to balance emotions and promote a sense of calm and stability.
These beliefs have contributed to the enduring popularity of September birthstones in jewelry and personal adornment. Whether worn for their beauty, their symbolic meanings, or their protective properties, these gemstones continue to be cherished by many.
Care and Maintenance of September Birthstones
Proper care and maintenance are essential to preserving the beauty and value of September birthstones. Each gemstone has its own specific requirements for cleaning and handling, based on its hardness, composition, and sensitivity to heat and chemicals.
Sapphires are relatively easy to care for due to their high hardness and durability. They can be cleaned with warm, soapy water and a soft brush to remove dirt and grime. Ultrasonic cleaners are also safe for sapphires, provided the gemstone is free of inclusions that could be damaged by the vibrations. Sapphires should be stored separately from other gemstones to prevent scratches and abrasions.
Lapis lazuli, on the other hand, requires more delicate handling. It is a softer gemstone and is sensitive to acids, solvents, and harsh chemicals. It should be cleaned with a soft cloth and mild soap, and should never be exposed to ultrasonic or steam cleaners. Lapis lazuli should also be stored in a soft pouch to prevent scratches and damage.
Aventurine is also relatively easy to care for, but it should be handled with care to avoid scratches. It can be cleaned with warm, soapy water and a soft cloth, and can be stored in a separate container to prevent contact with other gemstones.
In general, September birthstones should be inspected regularly for loose settings or damage, especially if they are worn frequently. They should also be kept away from extreme temperatures and direct sunlight, which can cause fading or discoloration.
