Peridot: August’s Volcanic and Celestial Birthstone

Peridot, a gemstone celebrated for its vibrant yellowish-green to greenish-yellow hues, holds the distinction of being a primary birthstone for the month of August. Alongside spinel and sardonyx, peridot boasts a rich history interwoven with ancient lore and geological marvels. Its unique origins, sometimes found in hardened lava flows and even within meteorites, contribute to its enduring appeal. This article delves into the history, geological formation, gemological properties, symbolism, and care of this captivating gem, offering a comprehensive overview for enthusiasts and those seeking to understand the significance of August’s birthstone.

History and Lore

Throughout history, peridot has been subject to misidentification, often mistaken for other green gemstones like emerald and topaz. The island of Topazios in the Red Sea, from which the name “topaz” is derived, was, in fact, a significant source of peridot. This historical confusion highlights the gem’s visual similarities to other valued stones.

The peridot’s story extends into religious history as well. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is adorned with approximately 200 carats of gems previously believed to be emeralds, but now confirmed as peridot. This demonstrates the gem’s historical use in significant religious artifacts. Speculation even suggests that Cleopatra’s famed emerald collection may have largely consisted of peridot, showcasing its desirability among royalty and powerful figures. Sardonyx is noted as the original August birthstone, with a history spanning over 4,000 years, but peridot has risen in prominence as a favored choice for those born in August.

Geological Formation and Sources

Peridot is the gem variety of the mineral olivine, a silicate compound of magnesium and iron. Its formation occurs under extreme conditions, often within the Earth’s mantle. The gem can be brought to the surface through volcanic activity, found within the hardened lava that carried it from deep within the Earth. Remarkably, peridot has also been discovered in meteorites, originating from outer space, adding to its mystique and unique origin story.

While specific mining locations are not detailed in the provided sources, the gem’s association with volcanic regions suggests potential sources in areas with significant volcanic activity.

Gemological Properties

Peridot is characterized by its distinctive color range, spanning yellowish-green to greenish-yellow. This coloration is due to the presence of iron within its chemical composition. The sources do not provide specific details regarding its chemical formula, refractive index, or clarity characteristics. However, the gem is described as a variety of olivine, a silicate mineral.

The provided materials focus on peridot’s suitability for jewelry, noting its use in necklace charms, pendants, and as a gemstone in various settings. Several sources highlight its use in sterling silver settings, often paired with cubic zirconia crystals. The dimensions of some charms are provided, with a typical diameter of 7mm or 5mm for round-cut stones. One source details a charm with an outside diameter of 8.7mm and an interior diameter of 4.7mm, with a width of 3.2mm.

Symbolism and Metaphysical Beliefs

Peridot is associated with various beliefs regarding healing and protection. One source mentions that peridot is adorned with believed healing and protective properties, suggesting a historical and cultural association with well-being. While the specific nature of these beliefs is not detailed, the gem is presented as a meaningful gift choice, imbued with positive symbolism. The La Lune brand specifically connects its galaxy charms, including the peridot version, to the “chapters of your life” and “moments” that define one’s existence, suggesting a symbolic connection to personal memories and experiences.

Care and Cleaning

The sources provide practical advice on caring for jewelry containing peridot, particularly when set in silver. Silver is prone to tarnishing and benefits from storage in sealed bags or airtight boxes. Regular cleaning with a polishing cloth is recommended to maintain its shine. For gold settings, regular cleaning with a polishing cloth and avoidance of harsh chemicals are advised. The use of a Jewellery Cleansing Foam is also suggested for a lasting shine. The sources do not provide specific guidance on cleaning peridot itself, but given its mineral composition, gentle cleaning with mild soap and warm water is generally recommended for most gemstones.

Presentation and Purchasing Options

Peridot is frequently presented as part of charm necklaces or pendants, often crafted from sterling silver or gold-fill. Several sources highlight the availability of peridot charms, packaged in elegant jewelry boxes, making them suitable gifts. The sources also mention options for threading peridot charms onto existing necklaces or bracelets, allowing for personalized jewelry designs. Several brands offer peridot charms, including Birth Gems, Thread-On, The Charm Works, La Lune, and Seoidín. Purchasing options include online stores with shipping to various locations, as well as in-store pickup at select retailers.

Conclusion
