Peridot, the August 20 birthstone, is celebrated for its vibrant green hue, symbolic significance, and rich historical legacy. As one of the three August birthstones—alongside spinel and sardonyx—peridot stands out for its singular and striking color, which is caused by the presence of iron within its crystal structure. Unlike most other gemstones, whose colors are influenced by trace elements, peridot’s green is a direct result of its chemical composition. This makes it a unique and easily identifiable gemstone in the world of birthstones.
More than just an aesthetic gem, peridot has long been associated with positive energy, renewal, and emotional clarity. It has been used in jewelry and talismans for thousands of years, and its significance has endured from ancient Egypt to modern times. Whether worn for its beauty, its meaning, or its spiritual properties, peridot holds a special place in the hearts of gemstone enthusiasts and those born on August 20.
This article explores the history, geological properties, symbolic meaning, and care requirements of peridot, offering a comprehensive guide to this radiant green gemstone. We’ll also examine its role as a birthstone, its connection to friendship and passion, and the reasons behind its enduring appeal.
History and Lore
Peridot has a long and storied history, with its use and significance documented in various ancient cultures. In ancient Egypt, as early as 1500 BC, peridot was highly valued for both its beauty and its perceived healing properties. The Egyptians believed that peridot possessed the power to ward off nightmares and bring about a peaceful sleep. It was commonly used in jewelry and religious artifacts, and it was especially popular among the elite for its vibrant green color, which symbolized life and vitality.
The gemstone was also revered in ancient Rome and Greece, where it was associated with the sun and was believed to bring good fortune. Roman soldiers were known to wear peridot as a protective amulet, and it was often engraved with the images of gods and heroes to provide courage and guidance in battle. The Romans also believed that peridot could bring about emotional clarity and balance, making it a popular choice for those seeking harmony in their personal and professional lives.
Peridot has also been found in the jewelry of the ancient Chinese and Indian cultures, where it was used in both decorative and ceremonial contexts. It was believed to bring about prosperity and success, and it was often gifted as a symbol of friendship and goodwill. In India, peridot was considered a sacred stone and was used in religious rituals and spiritual practices.
In the modern era, peridot gained official recognition as a birthstone in 1912, when the American Gem Trade Association (AGTA) and Jewelers of America (JA) included it in the list of birthstones for August. More recently, in 2016, spinel and sardonyx were added to the list of August birthstones to provide additional options for color, availability, and affordability. However, peridot remains the most iconic and well-known of the three, thanks to its unique green color and historical significance.
Geological Formation and Sources
Peridot is a type of olivine, a group of minerals that are commonly found in igneous rocks and volcanic settings. It is formed under high-temperature conditions and is often found in areas with volcanic activity. The presence of iron in its crystal structure is what gives peridot its distinct green color. The more iron present in the stone, the deeper the green hue becomes. Peridot can range in color from a pale yellow-green to a rich olive green, with the most desirable stones exhibiting a vibrant, saturated green.
The formation of peridot involves the cooling and solidification of magma, during which the iron-rich minerals crystallize and develop into gem-quality stones. It is often found in basaltic lava flows and in the mantle of the Earth, where it can be brought to the surface through volcanic eruptions. Peridot can also be found in meteorites, making it one of the few gemstones that can be traced back to extraterrestrial origins.
The most notable sources of peridot include:
Zabargad Island (St. John’s Island): Located in the Red Sea between Egypt and Saudi Arabia, Zabargad is one of the most famous sources of peridot. The island has been known for its gemstone deposits for thousands of years and was a major supplier of peridot during the ancient Egyptian era.
United States: Peridot is also found in the United States, particularly in Arizona, New Mexico, and Hawaii. Arizona is especially known for producing high-quality peridot, and it is considered one of the most accessible sources of the gemstone.
Myanmar (Burma): Myanmar is another significant source of peridot, with deposits found in the Mogok region. The peridot from this region is known for its deep green color and excellent clarity.
Madagascar and Pakistan: These countries also produce peridot, with deposits found in various locations. The peridot from these regions is often used in jewelry and is prized for its vibrant color and affordability.
In addition to natural sources, peridot can also be synthesized in laboratories. However, natural peridot remains the most highly valued due to its unique color and historical significance.
Gemological Properties
Peridot is a gemstone that is both visually appealing and scientifically interesting. Its unique properties make it a popular choice for jewelry, especially for those who are drawn to its vibrant green color and its relatively affordable price point compared to other gemstones.
Color
Peridot is known for its striking green color, which is caused by the presence of iron in its crystal structure. The most desirable peridot stones exhibit a deep, rich green color that ranges from a pale yellow-green to an olive green. The intensity of the color is influenced by the amount of iron present in the stone. Stones with higher iron content tend to have a deeper green hue, while those with lower iron content may appear more yellow or brownish.
Hardness and Durability
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which makes it relatively durable but not as hard as some other gemstones like diamonds or rubies. While it is suitable for use in jewelry, it is important to take proper care of peridot to avoid scratches and damage. Peridot can be scratched by harder materials, so it is best to store it separately from other gemstones and to avoid exposing it to harsh chemicals or abrasive surfaces.
Clarity and Inclusions
Peridot is typically found with inclusions, which are natural imperfections that occur during the formation of the gemstone. These inclusions are often visible to the naked eye and can take the form of small crystals or tiny gas bubbles. While inclusions are common in peridot, they do not typically affect the overall beauty or value of the stone. In fact, some collectors and gemologists appreciate the unique character that inclusions add to a peridot stone.
Cut and Shape
Peridot is often cut into a variety of shapes, including round, oval, emerald, and cushion cuts. The most common cut for peridot is the round brilliant cut, which enhances its brilliance and sparkle. Peridot can also be cut into faceted shapes or cabochons, depending on the desired effect. The choice of cut can influence the overall appearance of the stone and can highlight its unique color and clarity.
Refractive Index and Luster
Peridot has a refractive index of 1.65 to 1.70, which gives it a moderate level of brilliance and fire. The luster of peridot is vitreous, meaning it has a glassy, shiny appearance. This luster enhances the gemstone’s beauty and makes it a popular choice for jewelry.
Chemical Composition
Peridot is a type of olivine, a group of minerals that are composed of magnesium and iron silicates. Its chemical formula is (Mg,Fe)₂SiO₄, which indicates that it is a solid solution between forsterite (Mg₂SiO₄) and fayalite (Fe₂SiO₄). The proportion of magnesium to iron in the stone determines its color, with higher iron content resulting in a deeper green color.
Specific Gravity and Density
Peridot has a specific gravity of 3.3 to 3.5, which means it is relatively dense for a gemstone. This density contributes to its weight and can be an important factor in determining its value and quality.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with positive energy, emotional clarity, and renewal. In ancient cultures, it was believed to have healing properties and was used in jewelry and talismans to promote well-being and balance.

To prevent scratches, it is best to store peridot jewelry separately from other gemstones and jewelry. Peridot can be scratched by harder gemstones like diamonds, rubies, and sapphires. It is also a good idea to store peridot in a soft cloth or a padded jewelry box to prevent it from coming into contact with other jewelry.
Avoid Heat and Sunlight
Peridot should be kept away from excessive heat and direct sunlight, as this can cause the gemstone to fade or lose its luster. It is best to store peridot in a cool, dry place when not in use. Avoid wearing peridot in hot environments or during activities that involve high heat, such as cooking or welding.
Remove During Physical Activity
Peridot should be removed during physical activity or any activity that involves contact with abrasive surfaces. This can help prevent scratches and other damage to the gemstone. It is also a good idea to remove peridot before engaging in activities that involve water, such as swimming or bathing, to prevent exposure to chlorine or other chemicals.
Professional Cleaning
If peridot jewelry becomes heavily soiled or difficult to clean, it may be best to take it to a professional jeweler for cleaning. A professional jeweler can safely clean peridot using appropriate methods and can also inspect the jewelry for any potential damage or wear.
