Peridot, a vibrant green gemstone, holds the distinction of being the primary birthstone for the month of August. Revered for its cheerful hue and historical significance, peridot has captivated civilizations for centuries. This article delves into the history, geological origins, gemological properties, and cultural symbolism of this fascinating gem, drawing exclusively from available sources.
History and Lore
While the sources primarily focus on peridot as the August birthstone, its historical journey extends far beyond a single month. The origins of the name “peridot” are somewhat uncertain, though it is believed to derive from the Arabic word faridat, meaning “gem.” Ancient Egyptians held peridot in high esteem, referring to it as the “gem of the sun.” They believed it possessed protective powers and adorned themselves with peridot jewelry, even using it in funerary artifacts.
The sources do not detail extensive ancient lore beyond the Egyptian association with the sun. However, the use of peridot in jewelry and ornamental objects throughout history indicates its enduring appeal. Modern interpretations associate peridot with good fortune, prosperity, and wisdom, as reflected in its inclusion in Prenoa’s 1954 sixpence necklaces, where it symbolizes the journey of life and gathered wisdom.
Geological Formation and Sources
Peridot is a gem-quality olivine, a mineral formed under specific geological conditions. The sources do not provide a detailed explanation of olivine formation, but indicate that peridot is found in volcanic rocks. The most significant deposits of peridot are located in Egypt, though the sources do not provide a comprehensive list of mining locations. The sources do not mention any specific geological processes involved in peridot formation.
Gemological Properties
Peridot’s defining characteristic is its distinctive green color, ranging from olive to brownish-green to a vibrant yellowish-green. This color is due to the presence of iron in its chemical composition. While a precise chemical formula is not provided in the sources, peridot is identified as a type of quartz.
The sources do not provide detailed gemological data such as refractive index, specific gravity, or crystal system. However, Prenoa’s description of their peridot crystals suggests they are used as faceted birthstones, implying a degree of clarity and durability suitable for jewelry making. The sources do not provide information on peridot’s hardness or cleavage.

Symbolism and Metaphysical Beliefs
Throughout history, peridot has been attributed with various symbolic meanings and metaphysical properties. Ancient Greeks believed peridot bestowed the gift of prophecy and protection from disease. Modern interpretations, while not explicitly detailed in the sources, suggest peridot brings confidence and hope to the wearer.
The sources mention folklore associating peridot with banishing greed, selfishness, and carelessness, and stimulating the imagination. Other gemstones mentioned in the sources also have associated lore; for example, citrine is known as the “Success Stone” or the "Merchant's Stone," believed to bring prosperity and abundance, while coral is rumored to stimulate emotional healing and relieve stress. Pietersite is thought to have a connection to storms and is sometimes called the Tempest Stone, and is rumored to force personal change. Prehnite is rumored to ease worries and aid spirit communication.
Care and Cleaning
The sources offer limited guidance on peridot care. Prenoa includes a care kit with their sixpence necklaces, suggesting that peridot requires gentle cleaning to maintain its shine. Given that peridot is a relatively soft gemstone, it is advisable to avoid harsh chemicals, ultrasonic cleaners, and abrasive materials. Gentle cleaning with warm, soapy water and a soft cloth is recommended.
