For those born on August 28th, the birthstone is peridot, a captivating gem celebrated for its vibrant green hue and a history steeped in symbolism. This gemstone, a variety of the mineral olivine, has been treasured for centuries, representing renewal, growth, and good fortune. While peridot serves as the primary birthstone for the entire month of August, its significance for those celebrating a birthday on the 28th is particularly noteworthy, embodying a unique blend of beauty and positive attributes. This article will explore the history, geological origins, gemological properties, and symbolic meanings associated with this remarkable stone.
History and Lore
Peridot’s history stretches back millennia, with evidence of its use dating back to ancient civilizations. The name “peridot” is believed to originate from the Arabic word “faridat,” meaning “gem,” reflecting its long-held value. Throughout history, it was often confused with other green gemstones, notably emeralds, leading to instances where peridot was misidentified in historical collections. Many “emeralds” adorning medieval European cathedral treasures were, in fact, peridots.
Ancient cultures attributed various magical properties to peridot. It was believed to offer protection against nightmares and evil spirits, fostering a sense of peace and calm in the wearer. Its luminous green color led to associations with the sun, symbolizing energy and the ability to dispel darkness. The stone was valued for its perceived ability to bring prosperity and good luck, making it a favored gem among royalty and those seeking fortune. As a traditional gift for the 16th wedding anniversary, peridot symbolizes the enduring nature of a lasting relationship.
Geological Formation and Sources
Peridot’s formation is unique among gemstones. Unlike many gems that form in the Earth’s crust, peridot originates deep within the Earth’s mantle, forming over millions of years. This makes it a relatively rare gemstone, as it requires specific geological processes to bring it to the surface. The only other gem known to form at such depths is diamond.
Peridot crystals are carried to the Earth’s surface during volcanic eruptions, deposited in basalt rock as the magma cools and solidifies. While most peridot is sourced from this volcanic activity, rare instances have seen raw peridot stones found embedded within pallasitic meteorites, such as the Jepara meteorite discovered on the island of Java.
Gemological Properties
Peridot is a gem-quality variety of the mineral olivine, with a chemical formula of (Mg, Fe)₂SiO₄. It is notable for occurring in only one color: green, although the shade can vary from yellowish-green to olive to brownish-green, depending on the iron content within the crystal structure.
Key gemological properties of peridot include:
- Mineral: Olivine
- Color: Lime to olive green
- Hardness: 6.5-7 on the Mohs scale
- Transparency: Transparent to translucent
- Refractive Index: 1.654-1.690
- Crystal System: Orthorhombic
- Specific Gravity: 3.27-3.37
The Mohs hardness of 6.5-7 indicates that peridot is relatively durable, though it is susceptible to scratching and requires careful handling. Its refractive index contributes to its characteristic brilliance and sparkle. The green hue is directly related to its iron composition, with higher iron content resulting in a darker, more intense green color.
Symbolism and Metaphysical Beliefs
Peridot is rich in symbolic meaning, deeply rooted in ancient traditions and folklore. It symbolizes inner strength, resilience, and the ability to overcome challenges. The gemstone is believed to bring prosperity, good luck, and success to those born in August or who wear it as a talisman.
Beyond its association with good fortune, peridot is also linked to peace and calm. It is thought to possess a restful energy, promoting emotional balance and reducing stress. Historically, it was worn as a protective amulet against negative energies and evil spirits. Modern interpretations suggest that peridot can enhance creativity, motivation, and self-esteem.
Care and Cleaning
Due to its hardness of 6.5-7 on the Mohs scale, peridot requires careful handling to prevent scratches and damage. It is advisable to remove peridot jewelry before engaging in strenuous activities or when exposed to harsh chemicals.
Cleaning peridot is relatively straightforward. Warm, soapy water and a soft brush are generally sufficient to remove dirt and grime. Avoid ultrasonic cleaners and steam cleaners, as these can potentially damage the gemstone. After cleaning, rinse the peridot thoroughly with clean water and dry it with a soft cloth. Regular cleaning will help maintain its brilliance and luster.
Additional August Birthstones
While peridot is the primary birthstone for August, other gemstones are also associated with this month. Spinel and sardonyx are recognized as alternative or traditional August birthstones. Spinel is believed to connect individuals to their guardians, fostering self-respect, willpower, and creativity. Sardonyx is associated with courage, happiness, and protection. The association of multiple birthstones allows for a wider range of choices and personal preferences.
Zodiac Connections
Peridot is one of the Zodiac birthstones for Virgo (August 23 – September 22). Sardonyx is one of the Zodiac birthstones for Leo (July 23 – August 22). These connections further enhance the gemstone’s significance for individuals born under these signs, aligning with their personality traits and astrological influences.
