Historical Significance of the September 21st Birthstones
Sapphires: The Stone of Nobility and Faith
Sapphires, particularly the blue variety, have long been regarded as symbols of royalty, wisdom, and spiritual insight. As the official birthstone for September, sapphires have been treasured across cultures and eras. Ancient Greek and Roman elites believed that sapphires offered protection from harm and envy, while medieval clerics wore them as symbols of heavenly virtue. The sources indicate that sapphires were also believed to possess healing properties, including the ability to cure plague-related ailments and eye diseases.
In ancient Persia, sapphires were thought to be the reason the sky appeared blue, with the belief that the Earth rested on a massive sapphire. The term “sapphire” itself comes from the Greek word sappheiros, which has evolved into the modern usage we know today. The sources also mention that sapphires were valued for their rarity and beauty, and their association with fidelity and the soul made them ideal for engagement rings and royal regalia.
Lapis Lazuli: The Stone of Wisdom and Protection
Lapis lazuli, the alternative September birthstone, has a history nearly as storied as sapphire. This deep blue metamorphic rock has been used for thousands of years, particularly in jewelry and decorative art. The sources note that lapis lazuli was mined in Afghanistan for over 6,000 years and continues to be a primary source today. It is composed of lazurite, pyrite, and calcite, giving it a distinctive appearance with flecks of gold and white veining.
Historically, lapis lazuli was considered a stone of wisdom and truth. It was especially popular in ancient Egypt, where it was used in jewelry and amulets by royalty and priests. The stone’s association with intellect and clarity made it a favored material for ceremonial and spiritual purposes. In modern times, lapis lazuli remains a popular choice for September birthstone jewelry, especially as an alternative to the more expensive sapphire.
Jasper: The Stone of Stability and Emotional Balance
Jasper is another gemstone linked to September 21st, particularly in zodiac-related traditions. According to the sources, some astrologers consider jasper to be the zodiacal birthstone for those born on the cusp of Virgo and Libra. Jasper is a type of chalcedony, a microcrystalline quartz, and is known for its grounding and stabilizing properties. The sources suggest that jasper was used by ancient Egyptians as an amulet, often carved into symbols of power and protection.
One notable example is the jasper amulet of King Nechepsos, which was shaped like a rayed dragon and was believed to embody wisdom, strength, and sympathy. The name "jasper" is derived from the Greek iaspis and Latin iaspidem, and some sources suggest it may come from the French phrase j'espère, meaning "I hope," reflecting the stone’s association with optimism and resilience.
Geological Formation and Sources
Sapphires
Sapphires are a type of corundum, which is an aluminum oxide (Al₂O₃) mineral. The blue color of sapphires is typically due to trace amounts of iron and titanium. Sapphires form under high pressure and high temperature conditions in the Earth's crust, often in metamorphic or igneous rocks. The sources note that the most famous sources of sapphires include:
- Sri Lanka: Known for producing high-quality blue sapphires for centuries.
- Myanmar (Burma): Famous for its rich blue "pigeon’s blood" sapphires.
- Australia: A significant source of sapphires, especially in the state of New South Wales.
- Madagascar: A growing producer of sapphires in the 21st century.
Sapphires have a hardness of 9 on the Mohs scale, making them durable and suitable for everyday wear in jewelry. Their refractive index ranges between 1.76 and 1.78, and they are often cut in brilliant or step-cut styles to enhance their color and clarity.
Lapis Lazuli
Lapis lazuli is a metamorphic rock that forms from the alteration of igneous rocks under high pressure and temperature. It is composed primarily of lazurite, a sodium calcium aluminum silicate that gives it its signature blue color. The sources list the following major sources of lapis lazuli:
- Afghanistan: The most historically significant and still one of the most important sources.
- Italy and Russia: Used in ancient times and continue to produce lapis lazuli today.
- South America: Argentina and Chile are notable sources in modern times.
- North America: Canada and the United States also produce lapis lazuli, though it is less common.
Lapis lazuli has a hardness of 5–6 on the Mohs scale, which is relatively soft compared to sapphires. It is more prone to scratching and requires careful handling. Its refractive index varies depending on the composition, but it is generally lower than that of sapphires.
Jasper
Jasper is a form of chalcedony, a microcrystalline quartz that forms from the slow deposition of silica in sedimentary rock. The sources note that jasper is found in many parts of the world and is known for its rich colors and patterns. Some key sources of jasper include:
- Egypt: Known for its use in ancient times.
- Germany and the United States: Modern sources of various jasper types.
- India and Brazil: Also significant in jasper production.
Jasper has a hardness of 6.5–7 on the Mohs scale, making it more durable than lapis lazuli but still requiring care to avoid scratches. It is often used in beads, pendants, and carved figures due to its workability and natural patterns.
Symbolism and Metaphysical Beliefs
Sapphires: The Stone of Wisdom and Loyalty
Sapphires have long been associated with wisdom, loyalty, and spiritual insight. The sources indicate that sapphires were believed to protect the wearer from harm and envy, and they were worn by royalty as talismans. In medieval times, sapphires were thought to represent Heaven and were worn by clergymen as symbols of their divine calling. In modern metaphysical practices, sapphires are believed to enhance mental clarity, promote truthfulness, and support spiritual growth.
The sources also mention that sapphires are associated with the zodiac sign Virgo and are believed to aid in decision-making and intellectual pursuits. Their deep blue color is often linked to calmness, serenity, and emotional stability.
Lapis Lazuli: The Stone of Truth and Transformation
Lapis lazuli is often considered a stone of truth and transformation. It is believed to enhance wisdom, encourage self-awareness, and promote inner peace. In ancient times, lapis lazuli was used in rituals and ceremonies to connect with higher spiritual realms. It is also associated with the throat chakra and is believed to help with communication and self-expression.
Modern metaphysical practitioners use lapis lazuli to support intellectual clarity and emotional healing. It is also believed to protect against negative energies and promote a sense of calm and confidence. The sources note that lapis lazuli is particularly beneficial for those in learning or teaching roles, as it enhances mental focus and memory.
Jasper: The Stone of Stability and Strength
Jasper is often referred to as the "stone of strength" and is believed to provide grounding and emotional stability. The sources mention that jasper was used in ancient Egypt as an amulet to protect the wearer from harm and to bring balance to the body and mind. It is associated with the root chakra and is believed to help individuals stay centered and focused.
Jasper is also believed to support the immune system and promote physical vitality. It is considered a stone of optimism and resilience, making it a popular choice for those seeking emotional support during difficult times. Some sources suggest that jasper is particularly beneficial for those born on the cusp of Virgo and Libra, as it helps to balance the transition between these two zodiac signs.
Care and Cleaning
Sapphires
Due to their high hardness (9 on the Mohs scale), sapphires are relatively easy to clean and maintain. They can be cleaned with warm, soapy water and a soft cloth. Ultrasonic and steam cleaners are also safe for sapphires, provided there are no inclusions or fractures. However, sapphires should be stored separately from other jewelry to prevent scratches.
Sapphires are heat-resistant and can be exposed to high temperatures without damage. However, sudden temperature changes should be avoided to prevent thermal shock. It is also important to note that some sapphires may have been treated to enhance their color, and these treatments may affect their durability.
Lapis Lazuli
Lapis lazuli requires more careful handling due to its lower hardness (5–6 on the Mohs scale). It is more prone to scratching and can be damaged by harsh chemicals. It is recommended to clean lapis lazuli with a soft cloth and mild soap. Avoid using ultrasonic or steam cleaners, as these can cause damage to the stone.
Lapis lazuli should be stored in a soft cloth or jewelry box to prevent contact with harder gemstones. It should also be kept away from direct sunlight and excessive heat, as these can cause fading or discoloration over time.
Jasper
Jasper is relatively durable with a hardness of 6.5–7 on the Mohs scale. It can be cleaned with warm, soapy water and a soft cloth. Ultrasonic and steam cleaners are generally safe for jasper, but it is advisable to test these methods on a small area first.
Jasper should be stored in a dry place and away from other jewelry to prevent scratches. It is also sensitive to prolonged exposure to direct sunlight, which can cause fading. Jasper is a porous stone, so it should be kept away from harsh chemicals and oils, which can penetrate the surface and cause discoloration.
