History and Lore of August Birthstones
The concept of birthstones is deeply rooted in tradition, with references to gemstones associated with the months of the year dating back to ancient times. The origins of the August birthstones, particularly peridot and sardonyx, can be traced to early civilizations, where they were valued for their beauty and believed to carry protective and symbolic properties.
Peridot: The Gem of the Sun
Peridot has a long and storied history, with some of the earliest records of its use dating back to ancient Egypt. Known as the “gem of the sun,” peridot was believed to have protective properties and was often worn to ward off evil spirits. It was mined from the Red Sea island of Zabargad, known today as St. John’s Island. The gemstone was also found in meteorites, a fact that only added to its mystique and importance.
Ancient Egyptians and other early cultures believed that peridot carried the power of the sun and brought vitality and warmth to its wearer. This connection to the sun is reflected in its color—peridot is typically found in a range of green hues, from yellowish green to olive green. This color is unique to peridot and is one of the reasons it is so highly valued.
Peridot's association with the sun and its vibrant green color made it a popular choice in jewelry, especially during the summer months. It was often set in gold, which enhanced its brilliance and warmth. In medieval Europe, peridot was also used in religious jewelry and was believed to have healing properties.
Sardonyx: A Stone of Strength and Clarity
Sardonyx, a type of onyx, has a history that stretches back over 4,000 years. It is one of the oldest known birthstones and was highly prized in ancient civilizations such as Egypt, Greece, and Rome. Sardonyx is characterized by its bands of red and white or brown and white, giving it a striking contrast that makes it ideal for carved cameos and intaglios.
In ancient times, sardonyx was believed to bring strength, clarity, and protection. It was often used in signet rings and other forms of jewelry that required durability. The stone was also associated with good behavior and honesty, making it a popular choice among those who valued integrity and moral strength.
Sardonyx was particularly favored by Roman senators and other figures of authority, as it was believed to enhance leadership qualities and promote justice. The stone was also used in funerary jewelry, symbolizing protection in the afterlife.
Spinel: A Modern Addition to August
Spinel is the newest addition to the August birthstone lineup. Historically, spinel was often mistaken for ruby and other precious gemstones, which led to its underappreciation for centuries. However, in recent years, spinel has gained popularity due to its wide range of colors and its affordability compared to traditional gemstones like ruby or sapphire.
Spinel comes in a variety of colors, including red, pink, orange, and even blue and purple. This diversity makes it a versatile choice for August birthstone jewelry. The red and pink varieties of spinel, in particular, are associated with love and passion, making them ideal for romantic jewelry such as engagement rings and pendants.
The recent recognition of spinel as an August birthstone reflects a growing appreciation for gemstones that offer both beauty and affordability. As more people become aware of spinel's unique qualities, it is gaining popularity as a meaningful and stylish choice for those born in August.
Geological Formation and Sources of August Birthstones
Understanding the geological properties and sources of August birthstones provides insight into their rarity, durability, and beauty. Each of these gemstones forms under different conditions and is found in various locations around the world.
Peridot: A Green Gem from the Earth’s Mantle
Peridot is a variety of the mineral olivine, and its formation is closely tied to the Earth’s mantle. It is one of the few gemstones that can be found in meteorites, as it is formed under extreme conditions and brought to the surface by volcanic activity. Peridot is typically found in volcanic rocks, where it crystallizes from magma.
The most significant sources of peridot include Arizona, Myanmar, China, and Pakistan. In Arizona, peridot is found in basaltic lava flows, and it has been mined there for many years. Myanmar has long been a major source of fine-quality peridot, and the gemstone is still widely produced there today.
Peridot is known for its unique color, which ranges from yellowish green to olive green. This color is due to the presence of iron in the mineral structure. The gemstone is relatively soft compared to other gemstones, with a Mohs hardness of 6.5 to 7, making it suitable for jewelry but requiring careful handling to avoid damage.
Sardonyx: A Banded Stone with Ancient Roots
Sardonyx is a type of onyx, which is a form of chalcedony, a microcrystalline variety of quartz. It is characterized by its banded appearance, typically featuring red or brown bands over a white or light-colored base. The red bands are caused by the presence of iron oxide, while the white bands are due to the absence of impurities.
Sardonyx is found in several countries, including India, Brazil, Uruguay, the United States, and Germany. India has been a major source of sardonyx for centuries, and the stone was historically used in cameos and intaglios. Brazil and Uruguay also produce high-quality sardonyx, which is often used in modern jewelry.
Sardonyx has a Mohs hardness of 6.5 to 7, making it durable enough for everyday wear. Its banded pattern and smooth texture make it ideal for carving, which is why it has been used for cameos and other ornamental purposes for thousands of years.
Spinel: A Versatile and Colorful Gem
Spinel is a mineral that forms in a variety of colors due to the presence of different trace elements. It is found in both igneous and metamorphic rocks and is often associated with other gemstones such as corundum (the mineral that includes ruby and sapphire). Spinel is known for its brilliance and clarity, and it can be found in a wide range of colors, including red, pink, orange, blue, and even black.
The most important sources of spinel include Myanmar, Sri Lanka, Tanzania, and Vietnam. Myanmar has been a significant source of red and pink spinel, while Sri Lanka is known for its high-quality blue and violet spinel. Tanzania and Vietnam have also emerged as important sources of spinel in recent years.
Spinel has a Mohs hardness of 8, making it one of the harder gemstones and suitable for a wide range of jewelry applications. Its durability and affordability have contributed to its growing popularity as a gemstone option.
