August boasts a trio of recognized birthstones – peridot, sardonyx, and spinel – yet peridot stands as the primary and most widely recognized gem associated with this summer month. Celebrated for its distinctive green hue, ranging from pale yellow-green to vibrant lime, peridot carries a rich history steeped in symbolism, lore, and geological fascination. This article delves into the origins, properties, meanings, and care of peridot, exploring its significance as a birthstone and a gemstone cherished for centuries.
History and Lore
Peridot’s story stretches back millennia, with evidence of its use dating back to ancient civilizations. Ancient Egyptians held peridot in high esteem, referring to it as the “gem of the sun.” Priests adorned themselves with peridot during ceremonies, believing it possessed potent protective powers. This reverence stemmed from the gem’s vibrant green color, which mirrored the life-giving energy of the sun. Sailors of old also carried peridot, convinced it would ward off negativity and ensure safe voyages.
Throughout history, peridot has been associated with themes of renewal, strength, and protection. Its fiery origin – often formed deep within the Earth’s mantle and brought to the surface through volcanic activity – contributed to its reputation as a stone born of fire and light. Warriors were known to carry peridot as a shield against harm, believing it offered resilience and courage. The gem’s lush green color further connected it to growth, abundance, and prosperity, making it a symbol of wealth and vitality.
Geological Formation and Sources
Peridot is a gem-quality olivine, a mineral composed of iron and magnesium silicate. Unlike many gemstones that form in the Earth’s crust, peridot originates in the Earth’s mantle, a region far below the surface. It is brought to the surface through volcanic eruptions or, remarkably, is sometimes found within meteorites. This unique origin contributes to its relative scarcity, particularly in high-quality specimens.
While peridot can be found in various locations worldwide, certain areas are particularly renowned for their production. Historically, the Red Sea island of Zabargad (St. John’s Island) was a significant source, yielding peridot for over 3,500 years. Myanmar (Burma) is also known for producing exceptional peridot crystals. Other notable sources include the United States (Arizona), Pakistan, Vietnam, and Brazil. The volcanic origins of the gem mean it is often found in basaltic lava flows.
Gemological Properties
Peridot possesses a unique set of gemological properties that contribute to its beauty and desirability. It typically exhibits a bright, vitreous luster. The gem’s color, its most defining characteristic, is solely green, ranging from pale yellow-green to olive and vibrant lime. This consistent coloration distinguishes it from many other gemstones that come in a wider spectrum of hues.
Here’s a summary of peridot’s key properties:
| Property | Value |
|---|---|
| Chemical Formula | (Mg,Fe)₂SiO₄ |
| Hardness (Mohs) | 6.5 - 7 |
| Specific Gravity | 3.34 - 3.48 |
| Refractive Index | 1.654 - 1.683 |
| Crystal System | Orthorhombic |
| Cleavage | Poor |
Peridot’s hardness of 6.5 to 7 on the Mohs scale makes it relatively durable, suitable for everyday wear, especially when set in protective jewelry settings. However, its cleavage is poor, meaning it is more prone to chipping or fracturing if subjected to a sharp blow.
Symbolism and Metaphysical Beliefs
The symbolism associated with peridot is deeply rooted in its history and color. Throughout the ages, it has been seen as a stone of light, energy, and renewal. Its green hue symbolizes growth, abundance, and harmony, making it a fitting birthstone for those embarking on new chapters or seeking inner balance.
Peridot is believed to support emotional clarity, helping to release resentment and jealousy. It is also said to strengthen self-confidence and promote a sense of self-worth. Beyond its emotional benefits, peridot is thought to offer protection against fear, anxiety, and toxic relationships. In relationships, peridot is believed to represent loyalty, love, and harmony, making it a meaningful gift for loved ones. Some modern sources suggest peridot is considered the luckiest of the August birthstones, due to its long association with protection and good fortune.
Care and Cleaning
Peridot, while relatively durable, requires careful handling and cleaning to maintain its brilliance. Due to its lower hardness compared to gems like diamonds or sapphires, it is susceptible to scratches and abrasions. It is advisable to remove peridot jewelry before engaging in strenuous activities or when exposed to harsh chemicals.
Cleaning peridot is best done with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, as these can damage the gem. After cleaning, rinse the peridot thoroughly with clean water and dry it with a soft cloth. Regular cleaning will help preserve its vibrant color and luster. Setting peridot in durable 14K gold is recommended to enhance its longevity and protect it from damage.
Choosing the Right August Gemstone
While peridot is the primary August birthstone, sardonyx and spinel also offer compelling options. Sardonyx, with its striking banded patterns of red and white, symbolizes courage and strength. Spinel, available in a range of colors including red, pink, and blue, represents renewal and vitality. The choice ultimately depends on personal preference and the desired symbolism. However, peridot’s unique green color and rich history make it a particularly meaningful and popular choice for those born in August.
Conclusion
Peridot, the vibrant green gem of August, is more than just a beautiful stone. It is a symbol of renewal, protection, and prosperity, steeped in history and lore. From its ancient origins in the Earth’s mantle to its enduring appeal as a birthstone, peridot continues to captivate and inspire. Whether you are an August baby, a gemstone enthusiast, or simply appreciate the beauty of nature’s creations, peridot offers a unique and meaningful connection to the world around us.
