Peridot, spinel, and sardonyx serve as the birthstones for August, though peridot is most frequently recognized as the primary gem associated with this month. Characterized by its distinctive lime-green hue, peridot symbolizes strength, good fortune, and peace. This article will delve into the history, geological origins, gemological properties, and cultural significance of peridot, drawing exclusively from available sources.
History and Lore
The name “peridot” is believed to originate from the Arabic word “faridat,” meaning “gem.” Throughout history, this vibrant green stone has been prized and, at times, misidentified. In medieval Europe, many “emeralds” adorning cathedral treasures were later discovered to be peridots. This confusion highlights the gem’s visual similarity to its more well-known green counterpart.
Historically, peridot has been valued not only for its beauty but also for its perceived protective qualities. It was traditionally worn as a talisman against evil spirits. In medieval times, people believed peridot could ward off nightmares and aid sleep. The stone’s association with good luck and prosperity has endured for centuries, leading to its modern designation as a gift for the 16th wedding anniversary, symbolizing the lasting nature of a committed relationship.
The symbolism extends to personality traits associated with those born in August. Individuals born under the sign of August are often described as brave, cheerful, optimistic, and fearless in the face of challenges. Peridot is believed to amplify these positive characteristics, opening the wearer to new ideas and accentuating their talents, particularly in areas of invention, art, and creativity. While possessing strong wills and high standards, August-born individuals may also find peridot’s uplifting energy helps to balance their more challenging traits.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, with a chemical formula of (Mg, Fe)₂SiO₄. Unlike many gemstones formed through complex geological processes resulting in a variety of colors, peridot occurs in only one color: green. This unique hue arises from the presence of iron within its crystal structure, rather than trace elements as is common in other gems.
Peridot is sourced from various locations around the globe. Common sources include India, Brazil, Germany, Uruguay, and the United States. While relatively common, high-quality peridot stones are still considered valuable.
Gemological Properties
Peridot exhibits a range of specific gemological properties that define its characteristics and value.
| Property | Value |
|---|---|
| Mineral | Olivine |
| Color | Lime to olive green |
| Hardness (Mohs) | 6.5-7 |
| Transparency | Transparent to translucent |
| Refractive Index | 1.654-1.690 |
| Crystal System | Orthorhombic |
| Specific Gravity | 3.27-3.37 |
The color of peridot can vary from yellowish-green to olive to brownish-green, depending on the iron content. The most desirable color is a rich olive green. It is often referred to as the “evening emerald” due to its ability to glow even in low light conditions. The gem typically displays transparency, though some specimens may be translucent. Its hardness of 6.5 to 7 on the Mohs scale indicates moderate durability, requiring careful handling to avoid scratches and damage.
Symbolism and Metaphysical Beliefs
The green color of peridot is strongly associated with inner peace, harmony, growth, and prosperity. Green is often linked to nature and renewal, and peridot is believed to embody these qualities. The stone is thought to free the mind of envy, negativity, and thoughts that could harm relationships.
Beyond its association with positive emotions, peridot is also believed to boost confidence and self-esteem. Some sources suggest that the stone can help reduce anger and stress in the wearer, while also dispelling jealousy and warding off evil. Author Judy Hall suggests spinel, a fellow August birthstone, possesses refreshing properties and can renew energy after setbacks, encouraging humility in victory.
For those born in August, peridot is considered particularly potent, enhancing their natural strengths and providing luck and good fortune.
Care and Cleaning
Due to its moderate hardness, peridot requires careful handling and cleaning. While relatively durable, it can be scratched by harder materials. It is recommended to clean peridot jewelry with warm, soapy water and a soft cloth. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone. Regular cleaning will help maintain its brilliance and luster.
Spinel and Sardonyx: Alternative August Birthstones
While peridot is the primary birthstone for August, spinel and sardonyx also hold significance. Spinel is prized for its vivid red hue, often rivaling ruby, but it also comes in shades of pink, orange, purple, blue, and even black. Different colors of spinel have been given industry-specific names, such as rubicelle for yellow-orange, almandine for purple, sapphirine for blue, and chlorospinel for green.
Sardonyx, on the other hand, displays bold bands of red, brown, and white within a single stone. It symbolizes strength, courage, and protection and was historically used in amulets, cameos, and seals. Ancient Greeks and Romans believed sardonyx brought victory in battle and enhanced communication skills.
Conclusion
Peridot, with its radiant green hue and rich history, remains a captivating gemstone. As the primary birthstone for August, it embodies strength, good fortune, and peace. Its unique geological formation, distinct gemological properties, and enduring symbolism continue to make it a cherished gem for jewelry enthusiasts and those seeking its perceived metaphysical benefits. While spinel and sardonyx offer alternative options for August birthdays, peridot’s vibrant color and historical significance solidify its place as a truly special and meaningful gemstone.
