August, a month brimming with the warmth of summer and the promise of change, is uniquely adorned in the world of gemology by an array of traditional birthstones. While many months are associated with one or two stones, August stands apart with its rich tapestry of gemstones—each carrying its own geological, historical, and symbolic significance. The traditional August birthstones include sardonyx, carnelian, moonstone, topaz, alexandrite, sapphire, ruby, diamond, and peridot. These gems have traversed centuries, appearing in ancient calendars, medieval manuscripts, and modern jewelry alike. This article delves into the origins, properties, meanings, and uses of these traditional August birthstones, providing a comprehensive overview grounded in the detailed information from authoritative sources.
A Historical Overview of August Birthstones
The concept of birthstones is deeply rooted in history, with early records tracing back to the Breastplate of Aaron, mentioned in the Old Testament. This sacred artifact featured 12 gemstones, each representing one of the 12 tribes of Israel. Over time, these stones were mapped to the months of the year, forming the foundation for the modern birthstone system. However, the assignment of stones to months was not fixed and varied across cultures and time periods.
For August, the list of traditional birthstones has evolved significantly. In the early centuries AD, carnelian and sardonyx were prominent. By the 18th and 19th centuries, additional stones like moonstone and topaz were included in various traditions. The 20th century brought further additions, with the modern birthstone system in the United States and Britain officially recognizing peridot as the primary August birthstone.
The diversity of August birthstones reflects the global nature of gemstone lore. Ancient Roman, Hebrew, Hindu, and Tibetan calendars each assigned different stones to the month, often influenced by local mineral availability, zodiac associations, and cultural beliefs. For example, carnelian held significance in Roman and Hebrew traditions, while ruby was revered in the Hindu calendar. These historical variations underscore the rich and multifaceted heritage of August’s gemstones.
The Traditional August Birthstones and Their Origins
1. Sardonyx
Sardonyx has a long and distinguished history as an August birthstone. It was the official birthstone for August in the United States until the early 20th century, when peridot was adopted as the modern counterpart. Sardonyx is a banded variety of chalcedony, characterized by alternating layers of reddish-brown and white. This gemstone was widely used in ancient Rome for seals and signet rings, where its durability and clarity made it ideal for engraving.
In medieval Europe, sardonyx was believed to promote marital harmony and was often included in wedding rings and other tokens of affection. The stone was also thought to bring courage and protection to its wearer. According to historical texts, those born in August who lacked sardonyx in their possession were said to live "unloved and lone," a belief reflected in a 19th-century birthstone poem.
Sardonyx is still valued for its aesthetic appeal and symbolic meaning. It is found in various parts of the world, including India, Brazil, and the United States. Its versatility in jewelry design and its historical associations make it a cherished gemstone among collectors and historians.
2. Carnelian
Carnelian is another traditional August birthstone, particularly in the Roman, Italian, and Hebrew calendars. Like sardonyx, it is a variety of chalcedony, distinguished by its vibrant red to orange-red coloration. The stone’s name is derived from the Latin word "carnis," meaning "flesh," in reference to its warm, flesh-like hue.
Carnelian has been used for millennia in jewelry, amulets, and ceremonial objects. In ancient Egypt, it was believed to provide protection and vitality, while in Greece and Rome, it was associated with courage and energy. The stone was also linked to the zodiac signs of Leo and Virgo, both of which overlap with the month of August. As such, carnelian was often worn by individuals born during this time to harness its empowering qualities.
In modern gemology, carnelian is prized for its durability and affordability. It ranks 6.5 to 7 on the Mohs scale of hardness, making it suitable for a variety of jewelry applications, from rings to bracelets. Carnelian is found in many parts of the world, including Brazil, India, and the United States. Its historical and cultural significance, combined with its visual appeal, ensures its place as a traditional August birthstone.
3. Moonstone
Moonstone, with its ethereal glow, is a traditional August birthstone that has captivated gem lovers for centuries. It is a type of feldspar composed of alternating layers of orthoclase and albite, which create a phenomenon known as adularescence—a soft, shimmering light that appears to float just below the surface of the stone.
Moonstone has long been associated with feminine energy, intuition, and emotional balance. In ancient times, it was believed to be formed from moonbeams, and was often worn by women to enhance their natural grace and serenity. In India, moonstone is considered a sacred stone, associated with the moon god Chandra and believed to bring good fortune and protection.
The stone’s calming properties have made it a popular choice for those seeking emotional stability and inner peace. Moonstone is relatively soft, ranking 6 to 6.5 on the Mohs scale, so it requires careful handling and is best suited for earrings and pendants rather than rings. Despite its delicate nature, moonstone remains a beloved gemstone, known for its mystical beauty and gentle energy.
4. Topaz
Topaz is another traditional August birthstone that has been cherished across different cultures and eras. Historically, topaz was considered a yellow gemstone, and in the Middle Ages, it was believed to stimulate optimism and increase physical strength. However, the name "topaz" was often applied to any yellow or golden-colored stone, leading to confusion with other minerals.
Topaz is a silicate mineral with a hardness of 8 on the Mohs scale, making it more durable than many other gemstones. It occurs in a wide range of colors, including yellow, blue, pink, and even colorless. The blue varieties, known as "Paraiba topaz," are particularly valuable. Topaz is found in various parts of the world, including Brazil, Russia, and the United States.
In addition to its physical properties, topaz is associated with a number of symbolic meanings. It is believed to promote emotional balance, enhance memory, and bring clarity of thought. In some traditions, topaz is also considered a stone of love and friendship, making it a meaningful gift for August birthdays.
5. Alexandrite
Alexandrite is a rare and highly prized gemstone that holds a special place in the history of August birthstones. It is a variety of chrysoberyl and is known for its remarkable color change—shifting from green in daylight to a reddish hue under incandescent light. This phenomenon, known as the alexandrite effect, is one of the most fascinating optical properties in the gem world.
Alexandrite was first discovered in the Ural Mountains of Russia in the 19th century, and it was named after the Russian czar Alexander II. It quickly became a symbol of good fortune and was often used in royal jewelry. In the old Russian calendar, alexandrite was designated as the August birthstone, and it was believed to help connect the wearer with their spiritual guides while also fostering self-respect and creativity.
Due to its rarity and beauty, alexandrite is one of the most valuable gemstones in the world. It ranks 8.5 on the Mohs scale and is often cut in cushion or round shapes to enhance its color-changing effect. While natural alexandrite is extremely rare, synthetic varieties are now available, making the stone more accessible to collectors and jewelry enthusiasts.
6. Sapphire
Sapphire is a traditional August birthstone in the old Hindu, or Ayurvedic, calendar. It is a variety of corundum, the same mineral family as ruby, and is known for its deep blue color. However, sapphire can occur in a wide range of colors, including yellow, green, and even colorless, though the blue varieties are the most famous and valuable.
Sapphires have been revered for centuries for their beauty and symbolic meaning. In ancient times, they were believed to bring wisdom, protection, and divine favor. In medieval Europe, sapphires were often used in royal crowns and regalia, symbolizing power, purity, and nobility.
In the context of August birthstones, sapphire is associated with inner peace and emotional stability. It is believed to help counteract depression and promote a sense of calm and balance. Sapphires are also linked to the zodiac sign of Virgo, which overlaps with the month of August, further reinforcing their connection to this time of year.
Sapphires rank 9 on the Mohs scale, making them one of the hardest and most durable gemstones. They are found in various parts of the world, including Sri Lanka,缅甸, and Australia. The deep blue sapphires of Kashmir are especially prized for their intense color and velvety appearance.
7. Ruby
Ruby is another traditional August birthstone, specifically in the Hindu calendar. It is the red variety of corundum and is one of the most valuable and sought-after gemstones in the world. Rubies are known for their vibrant red color, which is caused by the presence of chromium in the crystal structure.
In ancient times, rubies were believed to bring courage, mental power, and protection. They were often used in royal jewelry and were considered symbols of power and passion. In Hindu tradition, rubies were associated with the Sun and were believed to bring vitality and energy to the wearer.
Rubies rank 9 on the Mohs scale, making them extremely durable and suitable for a wide range of jewelry applications. They are found in various parts of the world, including Myanmar, Thailand, and India. The most famous ruby deposits are in Myanmar, where the "pigeon’s blood" rubies are considered the finest in the world.
As a traditional August birthstone, ruby is associated with strength, confidence, and vitality. It is a powerful stone that is often worn to enhance one’s willpower and emotional resilience.
8. Diamond
Diamond is a traditional August birthstone in the old Tibetan calendar. It is the hardest known natural substance, ranking 10 on the Mohs scale, and is composed of pure carbon. Diamonds are formed deep within the Earth’s mantle under extreme pressure and heat, and they are brought to the surface through volcanic eruptions.
Diamonds have long been symbols of strength, purity, and eternal love. In Tibetan tradition, diamonds were believed to protect the wearer from misfortune and to bring good fortune. They were also associated with spiritual enlightenment and were often used in religious and ceremonial contexts.
Diamonds come in a wide range of colors, including colorless, yellow, blue, and pink. Colorless diamonds are the most common, while colored diamonds are rarer and often more valuable. The value of a diamond is determined by the "4 Cs"—carat weight, color, clarity, and cut.
As a traditional August birthstone, diamond is associated with protection, strength, and spiritual clarity. It is a timeless gemstone that continues to captivate gem lovers around the world.
9. Peridot
Peridot is the modern August birthstone in the United States and Britain. It is a silicate mineral known for its vibrant green color, which can range from yellow-green to deep olive green. Peridot was once known as chrysolite, a name derived from the Greek words for "gold" and "stone."
Peridot has a long and fascinating history. It was one of the first gemstones to be discovered in meteorites, and it was often worn as a protective stone in ancient times. In medieval Europe, peridot was believed to reduce stress and protect the wearer from negativity.
Peridot ranks 6.5 to 7 on the Mohs scale, making it relatively durable but still requiring care to prevent scratches. It is found in various parts of the world, including the United States, Pakistan, and Egypt. Peridot is particularly abundant on the island of Zabargad, off the coast of Egypt, where it has been mined for centuries.
As a modern August birthstone, peridot is associated with optimism, renewal, and emotional healing. It is a versatile gemstone that is often used in rings, earrings, and pendants.
