History and Lore
The September birthstone, sapphire, has a long and storied history that dates back to ancient times. The name "sapphire" is derived from the Greek word sappheiros, which referred to the blue gemstone. In ancient Greece and Rome, sapphires were believed to protect their wearers from harm and envy. They were often worn by the elite, symbolizing wisdom, truth, and divine favor.
During the Middle Ages, sapphire took on a spiritual dimension. Clerics wore sapphires to symbolize Heaven, as the gemstone was thought to be a reflection of the divine. The gem was also believed to have healing properties; medieval Europeans thought that sapphire could cure plague boils and diseases of the eye. It was also considered an antidote to poison.
Sapphire has long been associated with royalty and nobility. In many cultures, it was the gemstone of choice for crowns and royal regalia. The deep blue color was seen as a symbol of power and sovereignty. Ancient Persians believed the Earth rested on a giant sapphire, which gave the sky its blue color. This belief underscores the gemstone’s association with the celestial and the divine.
In modern times, sapphire continues to be a symbol of luxury and elegance. It is often used in fine jewelry, particularly in engagement rings and anniversary gifts. The September birthstone remains a popular choice due to its beauty, durability, and rich history.
Geological Formation and Sources
Sapphire is a gemstone formed from the mineral corundum, which is composed of aluminum oxide (Al₂O₃). In its pure form, corundum is colorless, but trace elements within the crystal structure give it different colors. The blue color of sapphire is primarily due to the presence of trace amounts of iron and titanium. Other elements can produce sapphires in a range of colors, including pink, yellow, green, and even colorless, which are often referred to as "white sapphires."
Sapphire is formed deep within the Earth's crust under conditions of high temperature and pressure. The gemstone is typically found in metamorphic rocks, where it forms through the transformation of existing rock under heat and pressure. It can also be found in igneous rocks, where it crystallizes as magma cools.
Sapphire is mined in various parts of the world, with some of the most notable sources including:
- Afghanistan: Known for producing some of the finest blue sapphires in the world.
- Sri Lanka: A major producer of sapphires, particularly in a range of colors.
- India: Historically a significant source of sapphire, especially in the state of Kashmir.
- Myanmar (Burma): Known for its "Kashmir sapphires," which are prized for their deep blue color and exceptional quality.
- Australia: A major source of sapphires, particularly in the state of Queensland.
- Madagascar: A growing source of high-quality sapphires, including some of the largest specimens.
Sapphire is a relatively rare gemstone, and high-quality stones with intense color and clarity are particularly valuable. The gemstone's durability, due to its high hardness on the Mohs scale, makes it suitable for a wide range of jewelry applications.
Gemological Properties
Sapphire is one of the hardest gemstones, with a hardness of 9 on the Mohs scale. This places it just below diamond, the hardest mineral at 10, and makes it highly resistant to scratches and damage. The gemstone's durability is one of the reasons it is so popular in jewelry, particularly in rings and bracelets that are worn daily.
Sapphire has a refractive index of 1.76 to 1.78, which gives it a brilliant luster and excellent light dispersion. The gemstone is typically transparent to translucent, with a vitreous (glassy) luster. Its color ranges from light blue to deep royal blue, with the most valuable stones exhibiting a rich, deep blue color known as "cornflower blue."
Sapphire is typically cut into various shapes, including round, oval, cushion, and princess cuts. The choice of cut depends on the shape and quality of the rough stone, as well as the desired final appearance. The gemstone is often set in a variety of metals, including gold, platinum, and silver.
Sapphire can be found in a range of sizes, from small melee stones to large, rare specimens. The largest sapphire ever found was the Star of Burma, which weighs 733 carats and is displayed in the Smithsonian Institution in Washington, D.C.
Symbolism and Metaphysical Beliefs
Sapphire has been associated with a wide range of symbolic meanings and metaphysical properties across different cultures and eras. In ancient times, sapphires were believed to protect their wearers from harm and envy. They were also thought to bring wisdom and truth to those who possessed them. The gemstone was often worn by royalty and the clergy, symbolizing their noble and divine status.
In medieval Europe, sapphire was believed to have healing properties. It was thought to cure diseases of the eye, including plague boils, and to be an antidote to poison. The gemstone was also believed to promote clear thinking and mental clarity, making it a popular choice for scholars and philosophers.
In modern times, sapphire is associated with loyalty, fidelity, and the soul. It is often given as a gift to symbolize enduring love and commitment. The September birthstone is also believed to bring good fortune and protection to its wearer. It is said to enhance spiritual connection and promote inner peace.
Sapphire is also associated with the zodiac signs of Virgo and Libra. It is one of the birthstones for Virgo (August 23 to September 22) and for Libra (September 24 to October 23). The gemstone is believed to enhance the positive traits of these signs, including intelligence, creativity, and harmony.
Care and Cleaning
Due to its high hardness on the Mohs scale, sapphire is a durable gemstone that is well-suited for daily wear. However, like all gemstones, it requires proper care to maintain its beauty and longevity. The following guidelines provide practical advice on how to clean and care for sapphire jewelry:
Cleaning
Sapphire can be cleaned using warm soapy water and a soft brush. The following steps can be followed:
- Soak the jewelry in warm soapy water for a few minutes.
- Use a soft brush, such as a toothbrush, to gently scrub the gemstone and its setting.
- Rinse the jewelry with warm water to remove any soap residue.
- Dry the jewelry with a soft, lint-free cloth.
Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the gemstone or its setting. If the sapphire has been heat-treated or dyed, it is particularly important to avoid exposing it to high temperatures or harsh chemicals, as this can alter its color or structure.
Storage
When not in use, sapphire jewelry should be stored in a soft cloth or a jewelry box to prevent scratches and damage. It is also a good idea to keep sapphire jewelry separate from other gemstones, as harder gemstones can scratch softer ones.
Professional Maintenance
It is recommended to have sapphire jewelry professionally inspected and cleaned by a jeweler every few years. A jeweler can check for loose stones, worn settings, and other potential issues that may affect the gemstone's appearance or security.
