History and Lore
The use of gemstones as symbols of zodiac signs and birth months has a long and storied history, dating back to ancient civilizations. In the case of Leo and August, the association with Peridot, Ruby, and Sardonyx reflects a blend of myth, tradition, and cultural significance.
Peridot, the primary birthstone for August and a secondary gemstone for Leo, has been cherished for centuries for its vibrant yellow-green hue and its purported positive energy. Known as the "gem of the sun," Peridot was highly valued in ancient Egypt and was believed to be a gift from the sun god. In medieval Europe, it was considered a talisman that brought good fortune and protected against nightmares. Its association with Leo is particularly fitting, as the stone is believed to enhance self-confidence and promote inner strength—qualities that resonate with the Leo personality.
Ruby, the traditional birthstone for July and a secondary gemstone for Leo, has an even richer historical background. Revered in ancient India as the "King of Gemstones," Ruby has long been associated with power, passion, and protection. In Vedic astrology, Ruby is considered one of the most important gemstones and is believed to influence the sun's energy. Its deep red color symbolizes courage and vitality—traits that align perfectly with the Leo sign’s bold and assertive nature.
Sardonyx, a banded chalcedony composed of onyx and sard, also has historical roots. It was widely used in ancient Rome, where it was believed to grant courage and strength to warriors. Sardonyx is a combination of the traditional onyx and the red sard, making it a unique stone that balances the fiery energy of Leo with a more grounded, disciplined approach. This duality makes Sardonyx a suitable gemstone for those who seek to harness their Leo traits while maintaining a sense of balance.
Together, these gemstones reflect the multifaceted nature of Leo and the month of August. Whether through the vibrant energy of Peridot, the fiery passion of Ruby, or the balanced strength of Sardonyx, each stone offers a distinct yet complementary influence on the Leo personality.
Geological Formation and Sources
Understanding the geological origins of a gemstone provides insight into its rarity, beauty, and value. Peridot, Ruby, and Sardonyx each have unique formation processes and sources that contribute to their distinct characteristics.
Peridot
Peridot is a variety of the mineral olivine and is one of the few gemstones that can form directly from molten rock in the Earth's upper mantle. This unique formation process gives Peridot its vibrant yellow-green color, which is caused by the presence of iron. Peridot is most commonly found in volcanic and metamorphic rocks, and it can also be found in meteorites, where it forms under high-pressure conditions.
The most significant sources of Peridot include:
- Zabargad Island (St. John’s Island): Located in the Red Sea, this island has been a primary source of Peridot for centuries. The deposits here are some of the richest and highest quality in the world.
- Arizona, USA: The United States is a major producer of Peridot, with Arizona being one of the most well-known sources. The gemstone is often mined from basaltic lava flows.
- Brazil and China: These countries also produce Peridot, though in smaller quantities compared to Zabargad Island and Arizona.
Peridot is relatively abundant and affordable, which contributes to its popularity as a birthstone. On the Mohs scale of mineral hardness, Peridot ranks between 6.5 and 7, making it durable enough for everyday jewelry use.
Ruby
Ruby is a variety of the mineral corundum and is formed under high-pressure and high-temperature conditions in the Earth’s crust. The presence of chromium gives Ruby its deep red color, which is often described as "pigeon's blood" when the gemstone exhibits a rich, saturated hue. Ruby is one of the most valuable and sought-after gemstones in the world due to its rarity and beauty.
The primary sources of Ruby include:
- Burma (Myanmar): Known for producing some of the finest Rubies in the world, particularly the "pigeon's blood" Rubies that are highly prized in the gem trade.
- Sri Lanka: A major producer of Ruby, Sri Lanka is known for its high-quality stones that range in color from deep red to pinkish red.
- Madagascar, Thailand, and Vietnam: These countries also produce Rubies, though the quality and color can vary.
Ruby ranks at 9 on the Mohs scale of mineral hardness, making it extremely durable and suitable for use in various types of jewelry.
Sardonyx
Sardonyx is a banded chalcedony that consists of alternating layers of onyx and sard. Chalcedony is a type of microcrystalline quartz, and its formation occurs over long periods of time in the cavities of rocks. The red color of sard is due to the presence of iron, while the white or gray bands are composed of onyx.
The primary sources of Sardonyx include:
- Brazil: Brazil is a major producer of Sardonyx, with large deposits found in the state of Rio Grande do Sul.
- India and Mexico: These countries also produce Sardonyx, though in smaller quantities compared to Brazil.
Sardonyx ranks between 6.5 and 7 on the Mohs scale, making it relatively durable for jewelry use. Its banded appearance makes it a popular choice for carved pieces and cabochons.
Gemological Properties
The gemological properties of a stone—such as its color, clarity, hardness, and chemical composition—play a crucial role in determining its value and suitability for jewelry. Below is a detailed breakdown of the gemological characteristics of Peridot, Ruby, and Sardonyx.
Peridot
- Color: Peridot is known for its vibrant yellow-green color, which ranges from light to dark shades. The intensity of the color is influenced by the amount of iron present in the stone.

- Hardness: Peridot ranks between 6.5 and 7 on the Mohs scale. While it is relatively durable, it is not as hard as Ruby or Sardonyx, so care must be taken when wearing Peridot jewelry.
- Chemical Composition: Peridot is a silicate mineral with the chemical formula (Mg,Fe)₂SiO₄. The presence of iron gives it its distinctive color.
- Refractive Index: Peridot has a refractive index of 1.65 to 1.69, which contributes to its glassy luster.
Ruby
- Color: Ruby is known for its deep red color, which is caused by the presence of chromium. The most valuable Rubies exhibit a "pigeon's blood" hue, which is a rich, saturated red with a slight purplish or pinkish overtone.
- Clarity: Ruby is often included, and the presence of inclusions can affect its clarity. The most valuable Rubies are those that are free of visible inclusions to the naked eye.
- Hardness: Ruby ranks at 9 on the Mohs scale, making it one of the hardest gemstones. This high hardness makes it ideal for use in rings and other types of jewelry that are worn frequently.
- Chemical Composition: Ruby is a variety of corundum with the chemical formula Al₂O₃. The presence of chromium gives it its red color.
- Refractive Index: Ruby has a refractive index of 1.76 to 1.78, which contributes to its brilliance and fire.
Sardonyx
- Color: Sardonyx is a banded chalcedony that consists of alternating bands of onyx and sard. The red color of sard is due to the presence of iron, while the white or gray bands are composed of onyx.
