Peridot, a gemstone celebrated for its lively green hue, holds a prominent place as the birthstone for those born on August 24th, and more broadly, as one of the three birthstones for the month of August. Revered throughout history and across cultures, this gem is often associated with positivity, prosperity, and growth. This article delves into the history, geological origins, gemological properties, symbolism, and care of peridot, providing a comprehensive overview of this captivating gemstone.
History and Lore
Peridot boasts a rich and fascinating history, often intertwined with misidentification and evolving beliefs. While August currently recognizes peridot, spinel, and sardonyx as birthstones, peridot holds the distinction of being the most classic and popular choice for the month. Its story stretches back millennia, with mentions in ancient texts and associations with royalty and religious significance.
Historically, peridot was frequently confused with other green gemstones, notably emerald and topaz. The island of Topazios in the Red Sea, believed to be a primary source of early peridot, ironically lent its name to the November birthstone, topaz. Ancient scholars often used the name “topaz” to refer to what is now known as peridot, particularly for amber to yellow-green gems. George Frederick Kuntz, in his 1913 publication, The Curious Lore of Precious Stones, highlights this historical ambiguity.
Evidence suggests peridot was valued as early as the Old Testament, with some scholars believing it was among the gems adorning the breastplate of the High Priest Aaron. Cleopatra herself was rumored to have favored peridot, potentially mistaking it for emeralds in her famed collection. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral features approximately 200 carats of gems initially believed to be emeralds, but later identified as peridot. This demonstrates the gem’s long-standing association with prestige and religious importance.
Geological Formation and Sources
Peridot is a gem variety of the mineral olivine, a silicate compound of magnesium and iron. Its formation occurs under specific geological conditions, often involving volcanic activity and even extraterrestrial origins. Peridot can be found in hardened lava, carried from deep within the Earth’s mantle, and remarkably, even within meteorites. This unique origin story contributes to its mystique and appeal.
While historically sourced from the Red Sea island of Topazios, modern peridot is primarily found in other locations. Significant deposits exist in the United States (Arizona), Myanmar (Burma), Brazil, Pakistan, and Vietnam. The quality and color intensity can vary depending on the source location, with some regions producing stones with a more vibrant green hue.
Gemological Properties
Peridot’s distinctive color is its most defining characteristic, ranging from yellowish-green to greenish-yellow and even olive green. The intensity of the color is directly related to the amount of iron present in the stone. The finest peridots exhibit a brilliant, pure green color without any noticeable brown or yellow undertones.
Here's a summary of key gemological properties:
| Property | Description |
|---|---|
| Mineral | Olivine |
| Chemical Formula | (Mg, Fe)₂SiO₄ |
| Color | Yellowish-green to greenish-yellow, olive |
| Hardness (Mohs) | 6.5 - 7 |
| Crystal System | Orthorhombic |
| Luster | Vitreous (glassy) |
Peridot possesses a vitreous luster, giving it a glassy appearance. Its hardness ranges from 6.5 to 7 on the Mohs scale, making it relatively durable but susceptible to scratching from harder materials. This moderate hardness requires careful handling and appropriate care to maintain its brilliance.
Symbolism and Metaphysical Beliefs
Throughout history, peridot has been imbued with various symbolic meanings and metaphysical properties. It is often referred to as the “gem of the sun” due to its warm, glowing green color. This association lends itself to beliefs surrounding positivity, happiness, and prosperity.
Peridot is believed to symbolize growth, abundance, and positive energy, resonating with the qualities of those born under its influence. The vibrant hue is often linked to the vitality of nature, embodying renewal, rejuvenation, and balance. Some traditions associate peridot with protection against negativity and the ability to enhance mental clarity. It is also considered a stone of compassion, promoting emotional well-being and fostering harmonious relationships.
Furthermore, peridot is recognized as the stone to celebrate the 16th year of marriage, symbolizing a long-lasting and prosperous union.
Care and Cleaning
Due to its moderate hardness, peridot requires careful handling and cleaning to preserve its beauty. Avoid exposing peridot to harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the stone.
Cleaning peridot is best achieved with warm, soapy water and a soft brush. Gently scrub the stone to remove any dirt or grime, then rinse thoroughly with clean water. Dry with a soft cloth. It is advisable to remove peridot jewelry before engaging in strenuous activities or when exposed to potential abrasions. Storing peridot pieces separately from harder gemstones will help prevent scratches and maintain their luster.
The Three Birthstones of August
While peridot is the most widely recognized and classic August birthstone, it shares the honor with sardonyx and spinel. Sardonyx, the original August birthstone, boasts a history dating back over 4,000 years and was featured in ancient religious artifacts. Spinel, the newest addition to the August birthstone family (officially recognized in 2016), was historically mistaken for ruby, gaining recognition for its own unique beauty and vibrant colors. The availability of three birthstones allows individuals born in August to choose a gem that resonates with their personal preferences and style.
Conclusion
Peridot, the vibrant green gem of August, is a gemstone steeped in history, symbolism, and geological wonder. From its ancient origins and frequent misidentification to its modern-day status as a beloved birthstone, peridot continues to captivate and inspire. Its association with positivity, prosperity, and growth makes it a meaningful gem for those born in August, and a beautiful addition to any jewelry collection. Whether admired for its aesthetic appeal or cherished for its metaphysical properties, peridot remains a timeless treasure, embodying the beauty and resilience of the natural world.
