Peridot, a gemstone celebrated for its lively green hue, holds a prominent position as the birthstone for August. Specifically recognized as the birthstone for August 24th, this gem boasts a rich history, captivating symbolism, and unique gemological properties. Throughout the ages, peridot has been revered for its association with positivity, prosperity, and inner strength, making it a cherished stone for both adornment and metaphysical purposes. This article delves into the multifaceted world of peridot, exploring its historical origins, geological formation, gemological characteristics, cultural significance, and practical care guidelines.
History and Lore
Peridot’s story stretches back centuries, with evidence of its use dating back to ancient civilizations. The gem has been historically confused with other green gemstones, notably emeralds and topaz, a misidentification that persisted for considerable periods. Many “emeralds” adorning medieval European cathedral treasures were, upon closer examination, revealed to be peridots. This historical ambiguity adds to the gem’s mystique and illustrates its enduring appeal.
References to peridot, or a gem believed to be peridot, appear in the Old Testament, and it was one of the twelve stones worn on the breastplate of the High Priest Aaron. Some scholars suggest that the “topaz” mentioned in historical texts may, in fact, have been peridot, due to the similar coloring and interchangeable use of the names. The island of Topazios, however, did not actually produce the November birthstone topaz, further complicating the historical record.
Beyond religious contexts, peridot has been valued across cultures. Its longstanding importance is highlighted by its presence in the Shrine of the Three Holy Kings, demonstrating the reverence it has inspired throughout history.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, with a chemical formula of (Mg, Fe)₂SiO₄. It is relatively rare in comparison to other gemstones, forming deep within the Earth’s mantle and brought to the surface through volcanic activity. This formation process results in peridot occurring in only one color – green – though the shade can vary from yellowish-green to olive to brownish-green, depending on the iron content within the crystal structure.
While specific mining locations are not detailed in the provided sources, the gem’s volcanic origins suggest it is found in areas with a history of volcanic eruptions.
Gemological Properties
Peridot possesses a distinct set of gemological properties that contribute to its unique beauty and value. Its hardness ranges from 6.5 to 7 on the Mohs scale, making it moderately durable and suitable for jewelry, though it requires careful handling to avoid scratches and damage.
Here's a summary of its key properties:
| Property | Value |
|---|---|
| Mineral | Olivine |
| Color | Lime to olive green |
| Hardness (Mohs) | 6.5-7 |
| Transparency | Transparent to translucent |
| Refractive Index | 1.654-1.690 |
| Crystal System | Orthorhombic |
| Specific Gravity | 3.27-3.37 |
The refractive index of peridot, ranging from 1.654 to 1.690, contributes to its brilliance and sparkle. Its transparency can vary, ranging from transparent to translucent, influencing the gem’s overall clarity and visual appeal.
Symbolism and Metaphysical Beliefs
Peridot is imbued with rich symbolism and metaphysical properties. It is often associated with strength, good fortune, peace, and protection. Historically, it was worn as a talisman against evil spirits, believed to ward off negativity and safeguard the wearer.

Care and Cleaning
Due to its moderate hardness, peridot requires careful handling and maintenance to preserve its brilliance and luster. While relatively durable, it is susceptible to scratches and damage from harsh chemicals or abrasive materials.
Cleaning peridot jewelry can be done with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and steam cleaners, as these can potentially damage the stone.
