Peridot, with its distinctive olive-green hue, stands as the primary birthstone for those born on August 22nd. It is one of three official birthstones for the month of August, alongside spinel and sardonyx. What sets Peridot apart is its unique geological origin; it is one of the few gemstones found not only in the Earth's mantle but also within meteorites that have traveled from outer space. This "cosmic" origin contributes to its allure and the rich history that spans millennia.
This comprehensive guide explores the multifaceted nature of Peridot, from its formation deep within the Earth and its historical significance as a treasured gem often mistaken for emerald, to its specific gemological properties and symbolic meanings. We will delve into the science and lore that make Peridot a gemstone of serenity, friendship, and spiritual growth.
History and Lore
The history of Peridot is long and often confusing, largely because the gemstone has been mistaken for other green stones throughout history. As a variety of the mineral olivine, Peridot has been valued in many ancient and medieval cultures. The word "Peridot" is believed to derive from the Arabic word faridat, meaning "gem."
Historical records and archaeological finds highlight the gem's ancient appeal. The Red Sea island of Topazios, a source that actually produced Peridot, is a purported origin for the name "topaz," leading to further confusion. Perhaps the most famous historical mix-up occurred in Germany's Cologne Cathedral. The Shrine of the Three Holy Kings is adorned with 200 carats of gems that were long believed to be emeralds but are, in fact, Peridot. This misidentification is not isolated; some historians speculate that Cleopatra's famous collection of emeralds may actually have consisted of Peridot.
In ancient times, Peridot was believed to ward off nightmares and bring the wearer happiness and strength. Its reputation as a protective stone continued into the Middle Ages, where it was used to drive away evil spirits and protect against enchantment.
Geological Formation and Sources
Peridot's formation process is extraordinary, occurring under extreme conditions that few other gemstones experience. It is the yellowish-green to greenish-yellow gem variety of the mineral olivine. Peridot can be found in the hardened lava that carries it from deep within the Earth’s mantle, and it has also been discovered in meteorites that traveled from outer space, solidifying its reputation as a "cosmic" gemstone.
While Peridot is found in various locations around the world, specific sources are renowned for producing high-quality material. Myanmar's Mogok Stone Tract is a prolific source where ruby, sapphire, and other gem minerals are found alongside Peridot. Gems from this region are so naturally lustrous that locals refer to them as "spirit polished."
Other significant sources include: * Tajikistan * Sri Lanka * Vietnam * Tanzania * Pakistan
The Luc Yen region in northern Vietnam has produced Peridot, contributing to the global supply of this vibrant green gem.
Gemological Properties
Peridot is prized for its distinctive color, which ranges from yellowish-green to deep olive green. Unlike many other gemstones, Peridot exists in only one color family—green—though the specific shade can vary. It is typically transparent with an intense, radiant hue.

However, based on its gemological nature as a variety of olivine, general best practices would apply. To maintain the stone's luster and integrity, it is advisable to clean Peridot with warm, soapy water and a soft brush. It should be protected from harsh chemicals and extreme temperature changes, which could potentially damage the gem. Due to its relative softness compared to stones like diamond or sapphire, Peridot jewelry should be stored separately to avoid scratching.

Its formation within the Earth's mantle and in extraterrestrial meteorites sets it apart from nearly all other gemstones.
