Beyond these two, other stones such as Carnelian, Onyx, and Sardonyx are also recognized within Leo's gemstone portfolio. This article explores the history, geology, gemological properties, and cultural symbolism of these stones, providing a comprehensive guide for gemstone enthusiasts and jewelry buyers.
History and Lore
The historical narrative of Leo's birthstones is deeply intertwined with ancient civilizations, royal patronage, and enduring metaphysical beliefs.
Peridot
Peridot possesses one of the most storied histories among gemstones. Its use dates back to at least 1500 BC in Ancient Egypt. The gemstone was notably mined on the volcanic island of Zebargad (also known as St. John's Island) in the Red Sea, a source that supplied the Egyptian empire for centuries. Peridot was cherished not only for its beauty but also for its protective qualities, believed to ward off evil spirits and nightmares. The name "peridot" is derived from the French word perit, which translates to "to pass through." This etymology is often interpreted as a reference to the gem's perceived ability to help individuals navigate life's challenges with strength and confidence—a trait highly valued by the ambitious Leo. In the context of zodiac lore, Peridot is celebrated for its connection to renewal, emotional clarity, and abundance. It is believed to encourage calmness, self-control, and security in Leos, helping to mitigate tendencies toward possessiveness and fostering a better sense of personal worth.
Ruby
Ruby has been revered for millennia across various cultures, particularly in Asia and the Middle East. Its deep, fiery red color has long been associated with passion, vitality, and power. Ancient warriors and royalty frequently wore rubies, believing the gemstone would invoke courage and protect them in battle. In many traditions, Ruby symbolizes the essence of life itself, representing the heart's emotional and physical vitality. For those born under Leo, Ruby is considered a stone that amplifies the sign's inner fire. It is believed to enhance creativity, leadership, and a zest for life, perfectly aligning with the Sun-ruled Leo's radiant and dynamic nature. The gem's historical role as a talisman for power and protection makes it a fitting companion for the Leo's natural leadership qualities.
Carnelian and Other Historical Stones
Carnelian, a member of the chalcedony family, is another stone with deep historical roots linked to Leo. It has been used since ancient times in amulets and talismans to provide protection and support to those in positions of authority. Its grounding properties and ability to enhance confidence and motivation made it a favorite among leaders and warriors. This historical use aligns seamlessly with the Leo's innate leadership and courage. Other stones like Sardonyx, a variety of onyx with red and white bands, were also used in ancient Roman and Greek signet rings and cameos, valued for their durability and striking contrast, symbolizing strength and protection.
Geological Formation and Sources
Understanding the geological origins of these gemstones adds a layer of appreciation for their unique characteristics.
Peridot
Peridot is the gem variety of the mineral olivine, with the chemical formula (Mg, Fe)₂SiO₄. Unlike many gemstones that form in the Earth's crust, Peridot is one of the few that crystallize deep within the Earth's mantle. It is brought to the surface through volcanic activity. The gem is typically found in peridotite, a dark igneous rock, and can also occur in basalt flows. Significant sources include the United States (Arizona and New Mexico), Pakistan, Myanmar, and historically, the island of Zebargad in the Red Sea. The gem's characteristic olive-green to yellowish-green color is due to the presence of iron within its crystal structure.
Ruby
Ruby is the red variety of the mineral corundum (aluminum oxide, Al₂O₃). Its color is derived from trace amounts of chromium. Ruby forms in metamorphic rocks, such as marble, and in alluvial deposits where it has been eroded from its original host rock. The finest rubies, known for their vivid "pigeon's blood" red, historically come from Myanmar (Burma), particularly the Mogok region. Other notable sources include Thailand, Sri Lanka, and parts of Africa and India. The gem's hardness on the Mohs scale (9) makes it exceptionally durable, suitable for everyday jewelry.
Carnelian
Carnelian is a translucent to opaque variety of chalcedony, a microcrystalline form of quartz (SiO₂). Its red-orange color is caused by iron oxide impurities. It forms in volcanic or metamorphic rocks and is often found in geodes or as nodules. Major sources include Brazil, India, and the United States. Its relative affordability and striking color have made it a popular stone for both historical artifacts and modern jewelry.

Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these gemstones.
Peridot

Avoid ultrasonic cleaners and steam cleaning, as the heat and vibrations can cause damage. Store it separately from harder gemstones to prevent scratches.
Ruby
Ruby's exceptional hardness makes it easy to care for. It can be cleaned with warm, soapy water and a soft brush. Ultrasonic cleaners are generally safe for untreated rubies, but caution is advised for stones with fractures or treatments.
