Peridot, a gemstone distinguished by its vibrant green hue, holds a prominent place as a birthstone for August. Historically often confused with other gems like emerald and topaz, peridot possesses a unique geological origin and a rich cultural history. This article will delve into the formation, properties, historical uses, and symbolism of peridot, drawing exclusively from available sources.
History and Lore
The story of peridot is interwoven with historical misidentification and enduring fascination. Originally known as “chrysolithos,” the name ‘peridot’ originates from the Peridot or Vereeniging mines in Egypt, where the gem was historically sourced from limestone matrices. Some historical accounts suggest that the “topaz” referenced in ancient texts may, in fact, have been peridot, particularly concerning the island of Topazios, which did not yield true topaz. This confusion stemmed from the similar amber to yellow-green coloration of both stones.
References to peridot appear in biblical contexts, with some scholars believing it was among the gems adorning the high priest’s breastplate and forming part of Jerusalem’s foundation stones. The gem’s history extends to the Shrine of the Three Holy Kings in Germany’s Cologne Cathedral, which features 200 carats of gems previously believed to be emeralds but now identified as peridot. A captivating, though potentially apocryphal, tale suggests that Cleopatra’s famed emerald collection may have largely consisted of peridot.
While peridot, spinel, and sardonyx are now recognized as the August birthstones, peridot holds a particularly long and storied past. It was the primary birthstone for August in the U.S. until the early 20th century, when spinel was added as a modern alternative. Sardonyx, the oldest August birthstone on record, predates even peridot in documented use.
Geological Formation and Sources
Peridot’s formation is remarkable, occurring under extreme geological conditions. It is found both in hardened lava, carried from deep within the Earth’s mantle, and within meteorites originating from outer space. This dual origin contributes to its mystique and allure. The gem is a variety of the mineral olivine, composed primarily of magnesium and iron. The presence of iron is responsible for peridot’s characteristic green color, with varying brilliance dependent on the iron content.
Historically, Egypt was a significant source of peridot, particularly from the mines on the island of Topazios in the Red Sea. Today, peridot is also found in other locations, though specific details regarding modern mining locations beyond Egypt are limited within the provided sources.
Gemological Properties
Peridot’s chemical formula is (Mg,Fe)2 SiO4, indicating its composition of magnesium, iron, silicon, and oxygen. It is classified as a semi-precious stone. The gem is known for its unique capacity to sparkle under both natural and artificial light, earning it the nickname “evening emerald.” However, it is crucial to distinguish peridot from emerald, as they possess distinct characteristics.
The sources do not provide specific details regarding peridot’s refractive index, clarity grading, or typical carat weights. However, they emphasize its consistent green coloration, ranging from yellowish-green to olive-green, as a defining characteristic. The most sought-after peridot stones exhibit a lime-green hue.

Symbolism and Metaphysical Beliefs
Throughout history, peridot has been associated with various symbolic meanings and metaphysical properties. It is linked to shelter, power, and recuperation, making it a popular choice for jewelry. Modern interpretations emphasize peridot’s ability to promote responsibility, self-awareness, and forgiveness. It is considered a stone that encourages individuals to acknowledge their mistakes and manifest their dreams.
Different cultures attribute unique qualities to peridot. In some traditions, it is believed to connect individuals to their guardians, fostering self-respect, willpower, and creativity. It is also associated with positive energy, enhancing confidence, optimism, and joy. Some sources suggest that peridot can stimulate the base chakra, increasing vitality.
Care and Cleaning

However, given its composition and hardness (which is not specified in the sources), it is reasonable to assume that peridot should be treated with care to avoid scratches or damage. Gentle cleaning with warm, soapy water and a soft cloth is likely appropriate. Further research beyond the provided sources would be necessary to provide comprehensive care instructions.
