September, a month of transition, is marked by a rich tapestry of symbolic and natural transformations. In the world of gemstones, the month is celebrated with a selection of stones that have long been revered for their beauty, durability, and spiritual significance. The most widely recognized September birthstone is the sapphire, a gemstone with a deep blue hue that has been cherished for millennia. Lapis lazuli, another historically significant gem, also holds a place among the September birthstones, alongside other stones such as peridot, agate, zircon, and moonstone.
This article explores the September birthstones in depth, with a primary focus on sapphire, the most prominent of the month’s gems. Drawing from historical accounts, geological insights, and cultural symbolism, the following sections will illuminate the enduring legacy of these stones and their relevance in both ancient and modern times.
History and Lore
The history of the September birthstones is as rich and varied as the stones themselves. Sapphire, in particular, has a long and storied past. In ancient Greece, sapphire was believed to be a protective stone that could ward off negative energy and promote truth. It was also considered a celestial stone, thought to connect the wearer with the heavens. In medieval Europe, sapphires were worn by clergymen because they symbolized Heaven. Ancient Persians even believed the earth rested on a giant sapphire, which made the sky appear blue.
Lapis lazuli, another September birthstone, was similarly revered in antiquity. Known for its deep blue color and flecks of gold, lapis lazuli was used by Egyptian royalty, including Pharaoh Tutankhamun, whose sarcophagus was adorned with the gemstone. In medieval Europe, lapis lazuli was ground into powdered form to create ultramarine pigment, a highly prized color used in religious paintings and manuscripts. The stone was also believed to promote mental clarity and serenity, making it a favored choice for scholars and spiritual seekers.
Peridot, another gemstone historically associated with September, has a more complex and sometimes controversial history. While it is listed in several ancient calendars as the September birthstone, it is now more commonly recognized as the birthstone for August. Despite this shift, peridot retains its connection to September in some traditions. Known for its vibrant green color, peridot was believed to bring positive energy and was used in rituals to ward off nightmares and bring protection.
Sardonyx, a banded variety of chalcedony, has also been linked to September. This gemstone was valued for its protective and grounding properties, and it was often used in amulets and talismans to promote strength and determination. In the Tibetan tradition, agate is considered a September birthstone. Agate, known for its wide range of colors and patterns, was believed to enhance intelligence and eloquence, making it a popular choice for those seeking clarity and communication skills.
Zircon, another gemstone associated with September in the Indian tradition, is known for its brilliance and fire, often mistaken for a diamond. It has been used in both spiritual and decorative contexts, symbolizing wisdom and divine insight.
Geological Formation and Sources
Sapphires are a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes sapphires from other corundum stones is the presence of trace elements that cause the coloration. The most well-known and highly valued sapphire is the deep blue variety, which is colored by the trace element iron (Fe). However, sapphires can be found in a wide range of colors, including pink, yellow, green, and even white.
Sapphires are formed deep within the Earth's crust, typically in metamorphic or igneous rocks, under high pressure and temperature conditions. The presence of trace elements such as iron, titanium, chromium, or vanadium determines the color of the sapphire. For example, the blue sapphire owes its hue to the presence of both iron and titanium.
Sapphires are found in various parts of the world, with some of the most famous sources being in Myanmar (Burma), where the "Pigeon's Blood" sapphire is found. Other notable sources include Sri Lanka, India, Thailand, and the United States. Each location produces sapphires with distinct coloration and quality, influenced by the geological conditions of the region.
Lapis lazuli, on the other hand, is a metamorphic rock composed primarily of lazurite, a sodium calcium aluminum silicate. It also contains other minerals such as pyrite, which gives it the characteristic flecks of gold, and calcite, which may appear as white streaks. Lapis lazuli is formed under high-pressure and high-temperature conditions, often in regions where ancient seas have undergone metamorphism.
The most famous source of lapis lazuli is Afghanistan, where it has been mined for thousands of years. Other notable sources include Russia, Chile, and Canada. The quality of lapis lazuli is determined by the dominance of the blue lazurite and the distribution of the gold flecks of pyrite. High-quality lapis lazuli is characterized by a rich, deep blue with a fine distribution of golden flecks.
Peridot, another September birthstone, is a silicate mineral known as olivine. It is formed in the Earth's mantle and brought to the surface through volcanic activity. Peridot is found in a variety of locations, including Arizona, Hawaii, and Egypt. The green color of peridot is due to the presence of iron within its crystal structure. Peridot is known for its hardness and is relatively durable, making it a popular gemstone for jewelry.
Sardonyx, a banded variety of chalcedony, is a form of quartz that is composed of silicon dioxide (SiO₂). It is formed from the deposition of silica-rich water in cavities within rocks. Sardonyx is known for its distinct banding of red and white or yellow and white layers, which give it a striking appearance. It is found in various parts of the world, including India, Brazil, and the United States.
Agate, another September birthstone in some traditions, is a microcrystalline variety of quartz. It is formed from the slow deposition of silica in the cavities of volcanic rocks. Agate is known for its wide range of colors and patterns, which can include stripes, bands, and even landscapes. It is found in many parts of the world, including Brazil, Mexico, and the United States.
Zircon, a mineral composed of zirconium silicate (ZrSiO₄), is found in various geological settings. It is often found in metamorphic and igneous rocks and is known for its high refractive index, which gives it a brilliant sparkle. Zircon is found in many parts of the world, including India, Thailand, and Brazil.
Gemological Properties
Sapphires are among the hardest gemstones, with a rating of 9 on the Mohs scale of mineral hardness. This makes them highly durable and suitable for use in jewelry that is worn daily. The refractive index of sapphires ranges from 1.76 to 1.78, and they exhibit a moderate to high dispersion, which gives them a subtle sparkle. Sapphires are also known for their excellent clarity and can be found in a variety of cuts, including round, princess, emerald, and pear shapes.
Lapis lazuli, while beautiful, is a softer gemstone with a hardness of 5 to 6 on the Mohs scale. This makes it more prone to scratches and requires careful handling and cleaning. Lapis lazuli has a refractive index of around 1.66 to 1.68, and it is opaque due to the presence of calcite and pyrite. It is often polished to a smooth, lustrous finish, which enhances its deep blue color and golden flecks.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable. It has a refractive index of 1.65 to 1.69 and is known for its vibrant green color and glassy luster. Peridot is often cut into round or oval shapes and is popular in both modern and antique jewelry designs.
Sardonyx has a hardness of 6.5 to 7 on the Mohs scale, which makes it suitable for use in jewelry. It has a refractive index of around 1.53 to 1.54 and exhibits a waxy to vitreous luster. The banded appearance of sardonyx makes it a popular choice for cameos and intaglios, as well as for use in rings and pendants.
Agate has a hardness of 6.5 to 7 on the Mohs scale and is known for its durability. It has a refractive index of 1.53 to 1.54 and exhibits a waxy to vitreous luster. The wide range of colors and patterns in agate make it a popular choice for both decorative and functional jewelry.
Zircon has a hardness of 6.5 to 7.5 on the Mohs scale and is known for its brilliance and fire. It has a refractive index of 1.92 to 2.01, which gives it a high dispersion and makes it appear similar to a diamond. Zircon is often cut into brilliant shapes to enhance its sparkle.
