For those born under the zodiac sign of Libra, spanning from September 23 to October 22, the birthstone is a subject of some variation. While September is traditionally associated with the sapphire, Libra also holds its own unique birthstone: peridot. This article delves into the rich history, symbolism, gemological properties, and cultural significance of peridot, the primary Libra birthstone, as well as the sapphire, the gemstone shared with September. It also explores the lesser-known association of sapphire with Libra, as well as the occasional mention of opal and turquoise in zodiac-related discussions.
Libra, represented by the Scales, is a sign known for balance, harmony, and a pursuit of fairness. These traits are mirrored in the characteristics of its birthstones. Peridot, with its vibrant green hue and calming properties, is particularly well-suited to Libra’s need for emotional equilibrium. Sapphire, a gemstone of nobility and wisdom, also resonates with the intellectual and aesthetic sensibilities of Libra natives. This article will explore both these stones in depth, offering a comprehensive look at their roles in the zodiac and the gemological world.
History and Lore
The Historical Significance of Peridot
Peridot is an ancient gemstone, with a history that stretches back thousands of years. It was highly valued in the ancient world, particularly in Egypt, where it was known as the "gem of the sun." The ancient Egyptians believed peridot was a gift from the sun god, Ra, and it was often used in jewelry and religious artifacts. Some of the most famous peridot deposits were found on the island of Zabargad, located in the Red Sea. This island, known in antiquity as "Topazios," was a key source of peridot for much of the ancient world.
In medieval Europe, peridot was thought to have protective and healing properties. It was believed to ward off nightmares and negative energies, and was often worn by travelers for protection. In some cultures, peridot was also associated with fertility and was used in rituals to promote the health and well-being of expectant mothers.
The connection between peridot and Libra is relatively recent in the grand scheme of gemstone history. Modern zodiac and birthstone associations began to take shape in the 20th century, with peridot being designated as the primary birthstone for Libra. This choice may have been influenced by peridot’s calming and balancing properties, which align well with the traits of Libra natives.
Sapphire and Its Royal Legacy
Sapphire, while not as strongly associated with Libra as peridot, is also mentioned in some zodiac and birthstone references for Libra. This is likely due to sapphire being the traditional September birthstone, and Libra being the sign that begins in September. Sapphires have a long and storied history, with a legacy of royal patronage and religious symbolism.
The word "sapphire" comes from the Greek word "sappheiros," meaning "blue." Sapphires are a variety of the mineral corundum, which is also the mineral group that includes ruby. Corundum is inherently colorless, and the presence of trace elements like iron, titanium, or chromium gives sapphires their various colors. The most famous and valuable sapphires are the deep blue varieties, but sapphires can also be found in shades of yellow, green, pink, and even colorless.
Sapphires have been treasured by royalty and religious figures throughout history. In ancient Greece and Rome, sapphires were believed to protect against harm and envy. During the Middle Ages, sapphires were worn by clergy as a symbol of Heaven, and they were also believed to cure eye diseases and neutralize poisons.
The connection between sapphire and Libra may stem from its association with wisdom, clarity, and nobility—qualities that are often attributed to Libra natives. While sapphire is more commonly linked with September and the Virgo-Libra transition period, it occasionally appears in zodiac-related discussions as an additional stone for Libra.
Geological Formation and Sources
Peridot: The Gem of Green Light
Peridot is a gemstone composed of the mineral olivine, a magnesium iron silicate. It is one of the few gemstones that can be found in a single color—green—though the intensity of the color can vary from a pale yellow-green to a deep olive. The color of peridot is due to the presence of iron within its chemical structure. The more iron present, the deeper the green color.
Peridot forms in the Earth’s mantle and is brought to the surface through volcanic activity. It is also found in meteorites, making it one of the few gemstones that can originate from outer space. The most well-known sources of peridot include:
- Zabargad Island (Egypt) – Historically the most important source of fine peridot.
- Arizona, USA – Known for producing high-quality peridot, particularly in the Green Valley area.
- Madagascar – A major modern producer of peridot.
- Brazil – Also a significant source, particularly for larger stones.
- Nigeria and Afghanistan – Additional sources of peridot, though often for lower-grade material.
Peridot is relatively common compared to other gemstones, which makes it more affordable and accessible. It is also known for its durability, with a hardness of 6.5 to 7 on the Mohs scale, making it suitable for everyday wear.
Sapphire: The Corundum of Royalty
Sapphires are formed deep within the Earth's crust under high pressure and temperature conditions. As a variety of corundum, sapphires are composed primarily of aluminum oxide, with trace elements responsible for their color. The most prized sapphires are the deep blue varieties, which contain iron and titanium in their crystal structure. Other colors, such as pink, yellow, and green sapphires, owe their hues to different trace elements.
The most famous sources of sapphires include:
- Ceylon (Sri Lanka) – Known for producing high-quality blue sapphires since ancient times.
- 缅甸 (Myanmar) – Particularly the Mogok region, which is famous for its intense blue "pigeon's blood" sapphires.
- Kashmir, India – Producing a rare and highly valued type of sapphire known for its velvety blue color.
- Australia – Known for producing a range of sapphire colors, including the popular "Padparadscha" (orange-pink) sapphires.
- Madagascar and Thailand – Modern sources of sapphires, with Madagascar being particularly prolific.
Sapphires are extremely durable, with a hardness of 9 on the Mohs scale, making them ideal for use in jewelry. They are also resistant to scratches and abrasion, which contributes to their long-lasting appeal.
Gemological Properties
Peridot: A Green Gem of Simplicity
Peridot is a relatively simple gemstone in terms of its properties, but it is no less beautiful or valuable. Here are some of its key gemological characteristics:
- Chemical Composition: Magnesium iron silicate (Mg₁.₈–₂.₁Fe₀.₂–₀.₄SiO₄)
- Color: Green, ranging from a light yellow-green to a deep olive green
- Hardness: 6.5 to 7 on the Mohs scale
- Refractive Index: 1.650 to 1.690
- Specific Gravity: 3.30 to 4.55
- Luster: Vitreous (glassy)
- Transparency: Transparent to translucent
- Crystal System: Orthorhombic
- Common Cuts: Round, oval, cushion, and emerald
Peridot is a singly refractive gemstone, meaning it does not exhibit double refraction like many other gemstones. It is also relatively soft compared to sapphires or rubies, so it is important to handle peridot jewelry with care to avoid scratches and chips.
Sapphire: The Noble Corundum
Sapphires are among the hardest and most durable gemstones, second only to diamonds in terms of hardness. Here are some of their key properties:
- Chemical Composition: Aluminum oxide (Al₂O₃) with trace elements causing color variation
- Color: Blue, pink, yellow, green, orange, and even colorless
- Hardness: 9 on the Mohs scale
- Refractive Index: 1.76 to 1.78
- Specific Gravity: 3.95 to 4.10
- Luster: Vitreous
- Transparency: Transparent to translucent
- Crystal System: Hexagonal
- Common Cuts: Round, oval, cushion, and emerald
- Special Properties: Sapphires can exhibit asterism (a star-like effect) when cut en cabochon, due to the presence of needle-like inclusions.
Sapphires are doubly refractive, meaning they can split light into two rays as it passes through the stone. This can give them a slight "double vision" effect when viewed from certain angles. Sapphires are also known for their brilliance and fire, particularly in the blue varieties, which are highly prized in the gemstone market.

Care and Cleaning
Peridot: Gentle Handling for a Delicate Gem
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively soft compared to other gemstones like sapphires and diamonds. As such, it is important to handle peridot jewelry with care to avoid scratches and damage.
To clean peridot, it is best to use a mild soap and warm water solution. A soft cloth or a soft-bristled brush can be used to gently scrub away any dirt or grime. Avoid using ultrasonic cleaners or steam cleaners, as these can potentially damage the stone or weaken the setting.
Peridot should be stored separately from harder gemstones to prevent scratching. It is also important to avoid exposing peridot to harsh chemicals or abrasive materials, as these can dull its luster or cause surface damage.
Sapphire: A Durable Gem for Everyday Wear
Sapphires are extremely durable, with a hardness of 9 on the Mohs scale, making them ideal for everyday wear. They are also resistant to scratches and abrasion, which makes them a popular choice for engagement rings and other types of fine jewelry.
Sapphires can be cleaned using a mild soap and warm water solution. A soft cloth or a soft-bristled brush can be used to gently scrub the stone. Ultrasonic cleaners are generally safe for sapphires, but it is important to check the setting and any other gemstones in the piece before using one.
Sapphires should be stored in a soft pouch or a jewelry box to prevent scratches. They should also be kept away from harsh chemicals and abrasive materials, as these can dull their luster or cause damage to the surface.
