The August birthstone, peridot, is a gemstone celebrated for its distinctive lime-green hue and a history steeped in symbolism and lore. A variety of the mineral olivine, peridot is a gem that has been prized for centuries, representing strength, good fortune, and peace. This article will delve into the history, geological origins, gemological properties, and cultural significance of peridot, offering a comprehensive overview of this captivating gemstone.
History and Lore
Peridot’s story stretches back millennia. Ancient civilizations recognized and revered this vibrant green stone, often associating it with sunlight and fire due to its formation and color. Egyptian priests are known to have adorned themselves with peridot in their ceremonies, believing it held potent powers. Sailors carried peridot as a talisman for protection during long sea voyages, safeguarding them from harm and ensuring safe passage.
Throughout history, peridot has been subject to misidentification. Many “emeralds” featured in medieval European cathedral treasures were, upon closer examination, revealed to be peridots. This confusion stemmed from the similar green coloration, highlighting peridot’s enduring appeal as a gemstone worthy of adornment and reverence.
The name “peridot” itself is derived from the Arabic word “faridat,” meaning gem, underscoring its long-held status as a precious stone. Its historical connection to themes of renewal, strength, and protection has solidified its place in folklore and tradition.
Geological Formation and Sources
Peridot originates from a unique geological process. Unlike many gemstones formed closer to the Earth’s surface, peridot develops deep within the Earth’s mantle. It is brought to the surface through volcanic eruptions or, remarkably, is found within meteorites. This origin contributes to its distinctive composition and vibrant color.
The mineral composition of peridot is ((Mg, Fe)₂SiO₄), indicating it is a silicate mineral containing magnesium and iron. The presence of iron is responsible for the varying shades of green observed in peridot, ranging from yellowish-green to olive and brownish-green.
While peridot can be found in various locations globally, specific sources are particularly notable. The gem is often associated with volcanic activity, and deposits are found in regions with a history of eruptions.
Gemological Properties
Peridot possesses a unique set of gemological properties that contribute to its beauty and desirability. Its color is its most defining characteristic, occurring exclusively in shades of green. This 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 |

| Transparency | Transparent to translucent |
| Refractive Index | 1.654-1.690 |

The Mohs hardness scale places peridot at 6.5 to 7, making it reasonably durable for everyday wear, especially when set in protective jewelry settings like 14K gold. Its refractive index contributes to its brilliance and sparkle. While generally transparent, some peridot stones may exhibit translucency, affecting their overall clarity.

Throughout history and across cultures, peridot has been imbued with rich symbolism and metaphysical beliefs. It is widely regarded as a stone of strength, symbolizing inner resilience and the ability to overcome challenges.
Peridot is also associated with good fortune and prosperity, believed to attract wealth and abundance to those who wear it. Its vibrant green color connects it to nature’s energy, fostering a sense of renewal and vitality.

Care and Cleaning
Peridot, with a hardness of 6.5 to 7 on the Mohs scale, requires careful handling to maintain its brilliance.

It is advisable to remove peridot jewelry before engaging in strenuous activities or when exposed to abrasive materials.
