September, the transition month from summer to autumn, is marked by the cool crispness of the air and the vibrant hues of fall. For those born in this month, the birthstone is a gem that embodies the essence of this transformation. Among the many gemstones associated with September, sapphire stands out not only for its stunning color and durability but also for its deep historical, cultural, and metaphysical significance. Recognized as the primary birthstone of September in both the United Kingdom and the United States, sapphire is celebrated for its symbolic meanings, its geological rarity, and its enduring beauty.
This article delves into the multifaceted nature of sapphire as the September birthstone. Drawing from historical records, gemological data, and cultural lore, we will explore its origins, its place in ancient and modern traditions, its geological properties, and the beliefs surrounding its metaphysical effects. Additionally, we will examine sapphire’s alternative counterparts in the September birthstone lineup and the rich symbolism associated with these gems.
History and Lore
The history of sapphire is as deep and luminous as the gemstone itself. The term "sapphire" is derived from the Greek word sappheiros, meaning "blue" or "precious stone," a name that reflects its most iconic and celebrated color. In ancient times, sapphire was revered not just for its beauty, but for the spiritual and mystical properties attributed to it. In Greek mythology, sapphires were believed to be the gem of the gods. The stone was associated with Zeus and Apollo, two of the most powerful deities in the Greek pantheon, symbolizing wisdom, divinity, and the heavens.
The association of sapphire with the divine extended beyond Greek culture. In medieval Europe, sapphire was often used in religious artifacts and was believed to represent faith and purity. During the Renaissance, the gemstone became a popular adornment among royalty and nobility, often embedded in crowns, pendants, and rings as a symbol of status and spiritual grace. In the 15th century, sapphire was considered a stone of truth, sincerity, and constancy—qualities that made it particularly favored by those seeking to express their devotion or loyalty.
The gemstone's historical significance is further reflected in its use as a royal stone. Many European monarchs, including the British royal family, have historically owned sapphire jewelry. For example, the famous "Kensington Sapphire," a large blue sapphire weighing 130 carats, is said to have been part of the Crown Jewels of England. This stone was later mounted into a brooch for Queen Alexandra and later given to the Duchess of York (later Queen Mary) in 1911.
While sapphire is now the most widely recognized birthstone for September, it is not the only one. The historical record reveals that various cultures have assigned different stones to the month of September, depending on the calendar and beliefs of the time. For instance, in the old Tibetan calendar, agate was considered the September birthstone, valued for its ability to enhance intelligence and eloquence. In the old Roman and Polish calendars, sardonyx held the title, prized for its protective qualities and association with courage. Meanwhile, in the Hindu calendar, zircon—especially its blue variety—was regarded as the September birthstone, symbolizing peace of mind and prosperity.
The shift in the September birthstone from these traditional options to sapphire likely occurred in the 20th century, when modern birthstone lists began to take shape. The American and British lists, which are now the most widely accepted, designated sapphire as the official September birthstone due to its widespread appeal, cultural symbolism, and gemological attributes.
Geological Formation and Sources
Sapphire is a member of the corundum mineral family, which is composed of aluminum oxide (Al₂O₃). In its purest form, corundum is colorless, but the presence of trace elements such as iron, titanium, chromium, and vanadium imparts the gemstone with its characteristic color. In the case of blue sapphire, the dominant elements are iron and titanium, which combine to produce the gem's signature deep blue hue. The intensity of the blue can vary depending on the concentration of these elements, with the most prized sapphires exhibiting a rich, velvety blue often referred to as "cornflower blue."
Sapphires are formed deep within the Earth's crust under high pressure and high temperature conditions. They typically occur in igneous rocks, particularly in basaltic and syenitic rocks, as well as in metamorphic rocks like gneiss and schist. The process of sapphire formation can take millions of years, during which the gemstone crystallizes from molten rock or through the transformation of existing minerals.
The world's most famous sapphire deposits are found in several key locations:
- Sri Lanka: Known as the "Gem Island," Sri Lanka has been a significant source of sapphires for centuries. The gemstones found here are often of high quality and are prized for their clarity and vibrant color.
- India: The Golconda region in India was historically renowned for producing some of the finest sapphires in the world. These sapphires were highly sought after by Mughal emperors and are known for their exceptional color and brilliance.
- Myanmar (Burma): Burmese sapphires, particularly those from the Mogok region, are considered among the most valuable. They are known for their deep blue color and strong body tone.
- Madagascar: In more recent years, Madagascar has emerged as a major sapphire-producing country. The gemstones from this region are often large and of high quality.
- Australia: Australia is one of the largest producers of sapphires by volume, with the most important deposits located in New South Wales and Queensland. While many Australian sapphires are heat-treated to enhance their color, they are generally of good quality.
Sapphires are typically mined through alluvial or underground methods. Alluvial mining involves sifting through riverbeds and stream sediments where sapphires have been naturally eroded and transported by water. Underground mining, on the other hand, involves digging into the Earth's crust to extract the gemstones from their host rock.
Once extracted, sapphires undergo a rigorous process of cutting and polishing to enhance their brilliance and color. The most common cut for sapphire is the emerald cut, which highlights the gemstone's clarity and depth. However, other cuts such as the round brilliant, cushion, and oval are also used depending on the shape and quality of the rough stone.
Gemological Properties
Sapphire is renowned for its exceptional hardness and durability, making it one of the most suitable gemstones for everyday wear. On the Mohs scale of mineral hardness, sapphire ranks at 9, just one point below diamond (which is a 10). This high hardness makes sapphire resistant to scratches and abrasions, ensuring that it maintains its luster and brilliance over time.
In terms of chemical composition, sapphire is composed of aluminum oxide (Al₂O₃). The presence of trace elements such as iron, titanium, and chromium gives sapphire its wide range of colors. While blue is the most iconic and widely recognized color for sapphire, the gemstone can also be found in other colors such as pink, yellow, green, purple, and even colorless. These varieties are often referred to as fancy sapphires.

Sapphire's refractive index ranges from 1.76 to 1.78, which contributes to its brilliance and light dispersion. Its specific gravity is between 3.95 and 4.10, indicating that it is relatively dense for a gemstone.
The cleavage of sapphire is basal and perfect, meaning that the gemstone can split along certain planes with relative ease. This makes it important to consider the orientation of the stone during cutting to avoid weakening the gemstone.
Due to its high hardness and durability, sapphire is often used in engagement rings, pendants, and earrings, especially for those who desire a gemstone that is both beautiful and long-lasting. Its versatility and resilience make it a popular choice for fine jewelry.
Symbolism and Metaphysical Beliefs
Throughout history, sapphire has been associated with a wide range of symbolic meanings and metaphysical properties. In many cultures, the gemstone has been seen as a symbol of wisdom, truth, and spiritual insight. Ancient Greeks and Romans believed that sapphire had the power to protect its wearer from harm and to promote inner peace. In medieval Europe, sapphire was often used in religious artifacts and was believed to represent faith, purity, and divine favor.
In modern times, sapphire is often associated with loyalty, trust, and sincerity. These qualities make it a popular choice for engagement rings, where it is seen as a symbol of enduring love and commitment. In addition, sapphire is believed to enhance mental clarity and emotional stability, making it a popular gemstone for those seeking to improve their focus and decision-making skills.
In the realm of metaphysical beliefs, sapphire is considered a stone of the third eye chakra, which is associated with intuition, wisdom, and spiritual awareness. It is believed to help individuals access their inner wisdom and connect with higher states of consciousness. Some practitioners also use sapphire for meditation, as it is thought to promote calmness and clarity of thought.
In addition to its spiritual and emotional properties, sapphire is also believed to have physical benefits. Some sources suggest that sapphire can help with skin conditions, digestive issues, and eye health. While these claims are not scientifically proven, they reflect the deep cultural and historical significance of the gemstone.
Care and Cleaning
Due to its high hardness and durability, sapphire is a relatively easy gemstone to care for. However, like all gemstones, it can be damaged if not handled properly. Here are some tips for maintaining the beauty and longevity of sapphire jewelry:
- Cleaning: Sapphire can be cleaned using a mild soap solution and a soft brush, such as a toothbrush. Gently scrub the gemstone and then rinse it with warm water. Avoid using ultrasonic cleaners or steam cleaners, as these can potentially damage the stone or the setting.
