Peridot, a gemstone celebrated for its distinctive green hue, holds the primary position as the birthstone for August. Alongside spinel and sardonyx, peridot represents those born in this late summer month, embodying growth, prosperity, and a connection to the natural world. This article will explore the history, geological origins, gemological properties, symbolism, and care of this captivating gem, drawing solely from available sources.
History and Lore
The story of peridot stretches back millennia, with evidence of its use dating back to ancient civilizations. For over 3,500 years, the primary source of peridot was the historic Zabargad Island in Egypt, a volcanic island in the Red Sea. The gem’s origins are somewhat shrouded in mystery, with the name “peridot” potentially derived from the Arabic word “faridat,” meaning “gem,” or the Greek word “peridona,” translating to “give in abundance.”
Throughout history, peridot has been associated with various beliefs and traditions. Its resemblance to the color of money has often linked it to prosperity and good fortune. Some sources suggest it was favored by Egyptian pharaohs, adorning their jewelry and religious artifacts. It was also considered a protective stone, warding off evil spirits and bringing good health. The gem was sometimes referred to as “Evening Emerald” due to its ability to maintain its vibrant color even under artificial light, a characteristic that distinguished it from other green gemstones.
Geological Formation and Sources
Peridot is formed deep within the Earth’s mantle, brought to the surface through volcanic activity. This unique origin contributes to its distinctive composition and properties. While peridot occurs in only one color – green – the shade can vary considerably, ranging from yellowish-green to olive to brownish-green. The color is determined by the amount and type of iron present within the mineral structure; ferrous iron (FeO) creates the green color, while ferric iron (Fe2O3) contributes to the more yellow shades.
Historically, Egypt was the most significant source of peridot. However, modern sources include Pakistan, particularly the Kashmir region, which produces stones with exceptional size and a pure lime-green color. Arizona, specifically the San Carlos Apache Reservation, also yields peridot, though typically in smaller sizes but with excellent clarity and color. Additional sources are found in China, Myanmar, and Vietnam. Notably, peridot has even been discovered within meteorites that have fallen to Earth, making it a truly extraterrestrial gemstone.
Gemological Properties
Peridot is a silicate mineral composed of iron and magnesium. It possesses a hardness of 6.5-7 on the Mohs scale, making it suitable for most jewelry applications, though it requires careful handling to avoid scratches or damage.
Here's a summary of its key gemological properties:
| Property | Value |
|---|---|
| Chemical Formula | (Mg,Fe)₂SiO₄ |
| Color | Yellow-green to Olive to Brownish-Green |
| Hardness (Mohs) | 6.5 - 7 |
| Luster | Vitreous |
| Transparency | Transparent to Translucent |
Peridot is one of the few gemstones that occurs in only one color, though variations in shade are common depending on the origin and iron content. Advanced spectral analysis reveals its unique color science, with a primary chromatic signature of 75% saturation and 85% brightness.
Symbolism and Metaphysical Beliefs
Throughout history, peridot has been imbued with symbolic meaning. It is associated with growth, prosperity, love, loyalty, and protection. Its vibrant green color connects it to nature and healing powers. The stone is linked to both the Zodiac signs of Virgo (August 23 – September 23) and Leo (July 23 – August 22), offering specific resonance for individuals born under these signs.
Some believe that peridot’s association with prosperity stems from its resemblance to the color of money. It has also been linked to duality and balance, particularly in Vedic and Zodiac astrology.
Care and Cleaning
Due to its hardness of 6.5-7 on the Mohs scale, peridot requires careful handling to prevent scratches. It is susceptible to damage from sharp blows and abrasive materials. Cleaning peridot jewelry is best achieved with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, as these can damage the stone. Regular cleaning will help maintain its brilliance and luster.
August Birthday Symbols and Color Palette
Peridot is not the only symbol associated with August. The birth flowers for August are the Gladiolus and Poppy, adding to the month’s rich color palette. Gladiolus displays a stunning range of colors, including pink, red, white, yellow, purple, and coral, symbolizing strength of character, remembrance, and integrity. Poppy contributes warm, vibrant colors in red, orange, pink, and white, representing peace, rest, and remembrance. Combined with peridot’s green, these symbols create a vibrant and energetic color palette that captures the abundance of late summer.
Conclusion
Peridot, the captivating green birthstone of August, boasts a rich history, unique geological origins, and enduring symbolism. From its ancient roots in Egypt to its modern sources in Pakistan and Arizona, this gemstone continues to fascinate and inspire. Its association with prosperity, growth, and healing, combined with its distinctive color and relatively accessible hardness, makes it a cherished gem for jewelry and a meaningful symbol for those born in the eighth month of the year.
