Introduction
September is a month of transition, both in nature and in the calendar of gemstone lore. Historically, the concept of birthstones has been used to associate specific gemstones with each month of the year, often as symbols of protection, guidance, or personal significance. The modern system of birthstones, which we recognize today, is primarily rooted in 20th-century traditions, but its origins can be traced back to ancient civilizations such as the Babylonians, Egyptians, and Greeks. Over time, various cultures have added their own interpretations, enriching the tapestry of September’s birthstone lore.
According to the provided sources, September is linked to seven different gemstones, including sapphire, lapis lazuli, peridot, sardonyx, moonstone, agate, and zircon. Each of these stones has its own distinct properties and meanings, making the month of September particularly rich in gemstone tradition. In this article, we will examine each of these gemstones in detail, exploring their geological characteristics, historical uses, and the symbolic meanings they have carried through time.
History and Lore
The history of September birthstones is deeply intertwined with the cultural and spiritual beliefs of various civilizations. The concept of birthstones is ancient, with early references found in the Hebrew Bible, where the High Priest Aaron wore a breastplate adorned with twelve stones representing the twelve tribes of Israel. While the exact identities of those stones remain debated, this tradition laid the foundation for later associations between gemstones and months of the year.
In the context of September, the gemstones associated with the month have evolved over time, influenced by different cultural calendars and traditions. The modern designation of sapphire as the September birthstone dates back to the 20th century, but earlier traditions recognized other stones as equally significant. For example, in ancient Rome, sardonyx was the September birthstone, believed to offer protection and enhance courage. In the old Tibetan calendar, agate served as the September birthstone, valued for its stabilizing properties. Meanwhile, in the Hindu calendar, zircon was considered the September birthstone, particularly in its blue variety, which was believed to bring inner peace and prosperity.
The transition from these traditional stones to the modern sapphire as the primary September birthstone reflects broader shifts in gemology and cultural practices. Sapphire, with its deep blue color and symbolic association with wisdom and nobility, has become the most widely accepted gemstone for September in contemporary times. However, the legacy of the other September birthstones remains an important part of the month’s gemstone heritage, offering a glimpse into the diverse ways in which different cultures have valued and used these stones.
Geological Formation and Sources
The geological properties of each September birthstone are as varied as their historical and cultural significance. These gemstones are formed through different geological processes and can be found in a range of locations around the world.
Sapphire
Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep blue color of sapphire is typically caused by trace amounts of iron and titanium. Sapphires can be found in a wide range of colors, including pink, yellow, green, and even colorless, but the blue variety is the most iconic and commonly associated with September.
Sapphires are formed under high pressure and high temperature conditions deep within the Earth's crust. They are often found in metamorphic and igneous rocks, particularly in areas with a history of tectonic activity. Some of the most famous sources of sapphire include Myanmar (Burma), Sri Lanka, Madagascar, and Australia. The sapphires from Myanmar, especially those from the Mogok region, are renowned for their intense blue color and are considered among the finest in the world.
Lapis Lazuli
Lapis lazuli is a metamorphic rock composed primarily of lazurite, with smaller amounts of other minerals such as pyrite, calcite, and augite. Its striking blue color, often with flecks of gold-like pyrite, has made it a highly valued gemstone for centuries. The name "lapis lazuli" is derived from the Latin words lapis, meaning "stone," and lazurum, meaning "blue."
Lapis lazuli is formed through the metamorphism of limestone under high pressure and relatively low temperature. The finest quality lapis lazuli is found in Afghanistan, where it has been mined for thousands of years. Other notable sources include Russia, Chile, and the United States. Lapis lazuli is not typically used in jewelry in its raw form but is often carved into beads, pendants, and decorative objects.
Peridot
Peridot is a gem-quality variety of olivine, a mineral composed of magnesium iron silicate. The color of peridot ranges from yellow-green to olive green, depending on the relative amounts of iron and magnesium in the crystal. The name "peridot" is derived from the French word pierre verte, meaning "green stone."
Peridot is formed in the Earth's mantle and is brought to the surface through volcanic activity. It is commonly found in basaltic rocks and is one of the few gemstones that can be found in its natural form in the United States, particularly in Arizona. Other major sources include Egypt, Myanmar, and China. Peridot is known for its durability and is often used in jewelry, especially in rings and earrings.
Sardonyx
Sardonyx is a type of onyx that contains alternating bands of sard (a reddish-brown to orange variety of chalcedony) and white or gray. The name "sardonyx" is derived from the Greek words sardion, meaning "sard," and onyx, meaning "onyx." This gemstone is known for its vibrant colors and striking patterns.
Sardonyx is formed through the deposition of silica-rich solutions in cavities within rocks. It is commonly found in sedimentary and volcanic rocks. Major sources of sardonyx include Brazil, India, and the United States. Sardonyx has been used in jewelry and decorative objects for centuries, particularly in ancient Rome, where it was believed to offer protection and enhance courage.
Moonstone
Moonstone is a type of feldspar that exhibits a phenomenon known as adularescence, which is the iridescent shimmer that gives the stone its ethereal, moon-like appearance. Moonstone is composed of alternating layers of orthoclase and albite, which scatter light and create the glowing effect.
Moonstone is formed in igneous and metamorphic rocks, particularly in pegmatites and schists. Major sources of moonstone include India, Sri Lanka, and Madagascar. The finest moonstone, known as "blue moonstone," is highly prized for its strong adularescence and is often used in jewelry.
Agate
Agate is a microcrystalline variety of quartz that is known for its banded patterns and wide range of colors. The name "agate" is derived from the Greek word achates, referring to a river in Sicily where the stone was first discovered. Agate is formed through the slow deposition of silica-rich solutions in the cavities of rocks.
Agate is found in many parts of the world, including Brazil, India, and the United States. Different varieties of agate, such as sardonyx and carnelian, have been used in jewelry and decorative objects for centuries. In the old Tibetan calendar, agate was considered the September birthstone and was believed to enhance intelligence and eloquence.
Zircon
Zircon is a silicate mineral that is known for its high refractive index and dispersion, which gives it a brilliance similar to that of diamonds. Zircon is found in a wide range of colors, including blue, green, yellow, and red. The blue variety is particularly popular and is often used as a diamond substitute in jewelry.
Zircon is formed in igneous and metamorphic rocks and is found in many parts of the world, including Thailand, Cambodia, and Australia. In the Hindu calendar, zircon is considered the September birthstone and is believed to bring peace of mind and prosperity. Zircon is also known for its durability and is often used in rings and pendants.
