September is a month of transition, marking the shift from summer to autumn and symbolizing reflection, balance, and transformation. In the world of gemstones, it is a month rich in variety and meaning, as it is associated with several stones, each carrying its own historical, cultural, and spiritual significance. The most widely recognized September birthstone is sapphire, with lapis lazuli and other gems also holding special importance. This article explores the history, properties, and symbolism of the primary September birthstones, offering a comprehensive look into the lore and science behind these cherished stones.
History and Lore of September Birthstones
The concept of birthstones dates back to ancient times, with roots in biblical and cultural traditions. One of the earliest references is found in the Old Testament, where Aaron’s breastplate is described as being adorned with twelve gemstones representing the twelve tribes of Israel. While these stones were not necessarily associated with birth months, their symbolic and spiritual significance laid the foundation for later traditions.
The Modern Birthstone: Sapphire
The modern birthstone for September is sapphire, a gemstone that has been revered across cultures and centuries. Sapphires are most commonly associated with the deep blue hue, but they can occur in a wide array of colors, including pink, yellow, green, and even colorless. In ancient Rome and Greece, sapphires were worn by the elite to ward off envy and to protect their health. Medieval Europeans believed that sapphires could treat ailments such as boils, eye diseases, and even poisoning.
The most famous sapphire in history is the 12-carat blue sapphire engagement ring that Prince Charles gave to Princess Diana, which was later worn by Duchess of Cambridge, Kate Middleton. This ring has become an enduring symbol of elegance and tradition, further cementing sapphire’s status as a regal and timeless gemstone.
Sapphires have long been associated with wisdom, truth, and spiritual insight. In medieval Europe, it was believed that sapphires could promote inner peace and clarity of thought. During the Renaissance, sapphires were considered symbols of loyalty and sincerity, making them popular choices for royal and noble families.
The Traditional and Alternative Birthstone: Lapis Lazuli
In Britain, lapis lazuli is often considered an alternative birthstone for September, although it also has a long history of being linked with the month in various traditions. Lapis lazuli, known for its striking royal blue color and flecks of golden pyrite, has been used since ancient times for adornment and spiritual purposes. It was found in the tombs of Egyptian Pharaohs, including the famous burial of King Tutankhamun, and was also used by artists to create the ultramarine pigment that was once more valuable than gold.
Lapis lazuli is often associated with truth, awareness, and spiritual enlightenment. In medieval Europe, it was believed to enhance intellectual clarity and communication, making it a favored stone among scholars and philosophers. It was also thought to protect the wearer from envy and negative influences, a belief that echoes its association with sapphire.
Other September Birthstones
In addition to sapphire and lapis lazuli, several other gemstones are associated with September in various traditions. These include sardonyx, agate, moonstone, zircon, and iolite.
- Sardonyx and agate are both types of quartz and are known for their grounding and protective properties. They were often used in ancient times for amulets and seals.
- Moonstone is a variety of feldspar known for its ethereal glow and is associated with emotional balance and intuition.
- Zircon, especially the golden variety, is prized for its brilliance and is often used as an alternative to diamonds.
- Iolite, sometimes called the "Viking’s Compass," was historically used by Norse sailors for navigation and is believed to enhance intuition and insight.
These stones, while not as widely recognized as sapphire and lapis lazuli, contribute to the rich tapestry of September’s birthstone lore.
Geological Formation and Sources
Understanding the geological formation and sources of a gemstone provides insight into its rarity, beauty, and value. Let’s explore the origins and mining locations of the most notable September birthstones.
Sapphire: Formation and Sources
Sapphires are a type of corundum, a mineral composed of aluminum oxide (Al₂O₃). The blue color in sapphires is due to trace amounts of iron and titanium, while other colors are caused by different trace elements. Sapphires are formed under high pressure and temperature conditions deep within the Earth’s crust, often in metamorphic rocks and igneous rock formations.
The most famous sources of sapphires include:
- Ceylon (Sri Lanka): Known for producing high-quality blue and pink sapphires.
- Kashmir, India: Sapphires from this region are highly prized for their intense blue color and silk-like appearance.
- Australia: A major producer of sapphires, especially the Padparadscha variety, which has a pink-orange hue.
- Myanmar (Burma): Famous for producing some of the most vibrant blue sapphires in the world.
- Madagascar and Thailand: Also significant sources of sapphires in various colors.
Sapphires are rated 9 on the Mohs scale of hardness, making them one of the hardest gemstones, second only to diamonds. This hardness makes them suitable for everyday wear in jewelry, especially in rings.
Lapis Lazuli: Formation and Sources
Lapis lazuli is a metamorphic rock composed primarily of lazurite, with other minerals such as pyrite and calcite. It forms when sodium-rich magma cools and reacts with surrounding rocks, creating the deep blue color that lapis lazuli is known for.
Major sources of lapis lazuli include:
- Afghanistan: The primary source for high-quality lapis lazuli, especially the imperial blue variety with golden pyrite flecks.
- Chile: Known for producing lapis lazuli with a lighter blue and more calcite.
- Russia and Argentina: Also produce lapis lazuli, though not as highly regarded as the Afghan variety.
Lapis lazuli is relatively soft, with a hardness of 5 to 6 on the Mohs scale, which means it requires careful handling to avoid scratches and damage.
Gemological Properties
Gemological properties are essential for understanding a stone’s appearance, durability, and value. Let’s examine the key properties of sapphire and lapis lazuli, the two most prominent September birthstones.
Sapphire
- Chemical Composition: Aluminum oxide (Al₂O₃)
- Hardness: 9 on the Mohs scale
- Color: Blue (most valuable), pink, yellow, green, colorless
- Refractive Index: 1.76–1.78
- Luster: Vitreous
- Specific Gravity: 3.95–4.03
- Crystal System: Hexagonal
