This article explores the geological properties, historical use, cultural symbolism, and practical care of peridot, with a focus on its presentation in white gold jewelry.
Introduction
Peridot is a magnesium iron silicate mineral that forms in the mantle of the Earth and is brought to the surface through volcanic activity. Its color ranges from a pale yellow-green to a rich olive-green, with the most valuable specimens exhibiting a deep, vivid green. Peridot is the birthstone for August and is often associated with renewal, healing, and positive energy. In modern jewelry, peridot is frequently set in white gold, a popular choice for its subtle luster and ability to highlight the gemstone’s natural hue. The combination of peridot and white gold creates a versatile and elegant piece of jewelry that is both meaningful and stylish.
History and Lore
Peridot has a long and storied history, with references dating back to ancient times. The gemstone was highly prized in ancient Egypt, where it was known as the "gem of the sun." The ancient Egyptians believed that peridot was a gift from the sun god, Ra, and used it in jewelry and amulets to protect against evil spirits and nightmares. The gemstone was also found in the fabled "Isles of the Blest" in the Red Sea, a source that was known to the ancients and is now believed to have been the island of Zabargad.
In medieval Europe, peridot was often confused with emerald due to its green color, and it was used in religious and royal jewelry. The gemstone was especially popular in the Byzantine Empire, where it was incorporated into imperial regalia. Peridot was also used in the decoration of churches and cathedrals, where it was believed to have protective and purifying properties.
Peridot’s association with light and purity has made it a symbol of hope and renewal. It is often given as a gift to celebrate new beginnings, such as births, anniversaries, and personal milestones. In modern times, peridot has become a popular birthstone for August, and its use in jewelry has expanded to include a variety of styles and designs.
Geological Formation and Sources
Peridot is a silicate mineral that forms in the Earth’s mantle and is brought to the surface through volcanic activity. It is typically found in igneous rocks such as basalt and peridotite, which are rich in magnesium and iron. The gemstone’s color is due to the presence of iron in its chemical composition, with the most vivid green stones containing a higher concentration of iron.
The primary sources of peridot include the United States, specifically in Arizona and Hawaii, as well as in countries such as Myanmar, China, and Brazil. In Arizona, peridot is found in basalt lava flows and is mined from open-pit mines. The gemstone is also found in volcanic glass, where it can be formed as a result of the rapid cooling of magma.
In addition to terrestrial sources, peridot has been found in meteorites, making it one of the few gemstones that can be sourced from space. These extraterrestrial peridots are believed to have formed under different conditions than their Earth-based counterparts and are of particular interest to geologists and gemologists.
Peridot is known for its relatively high hardness, with a rating of 6.5 to 7 on the Mohs scale. This makes it durable enough for everyday wear, although it is still susceptible to scratches and abrasions if not handled carefully. The gemstone also has a refractive index of 1.65 to 1.69 and a specific gravity of 3.3 to 4.4, which are important factors in determining its quality and value.
Gemological Properties
Peridot is a gemstone that is characterized by its unique chemical composition and optical properties. Its chemical formula is (Mg,Fe)₂SiO₄, which indicates that it is a silicate mineral composed of magnesium, iron, and oxygen. The presence of iron in the gemstone’s structure is responsible for its green color, with the intensity of the color varying depending on the concentration of iron.
Peridot is a uniaxial gemstone, meaning that it has a single optic axis. This property gives the gemstone a distinct pleochroism, where it can display different colors when viewed from different angles. The most common colors are green, yellow, and brown, with the green color being the most desirable and valuable.
Peridot has a refractive index of 1.65 to 1.69, which means that it has a moderate to high level of light refraction. This gives the gemstone a brilliant luster and a lively appearance when properly cut and polished. The gemstone also has a specific gravity of 3.3 to 4.4, which is relatively high for a silicate mineral. This density contributes to the gemstone’s weight and heft, making it feel substantial when held.
Peridot is known for its relatively high hardness, with a rating of 6.5 to 7 on the Mohs scale. This makes it durable enough for everyday wear, although it is still susceptible to scratches and abrasions if not handled carefully. The gemstone also has a vitreous luster, which gives it a glassy, bright appearance.
Peridot is typically cut into various shapes, including round, oval, cushion, and marquise, to enhance its brilliance and color. The most popular cut for peridot is the round brilliant cut, which maximizes the gemstone’s fire and sparkle. However, other cuts can also highlight the gemstone’s natural beauty and color.
Symbolism and Metaphysical Beliefs
Peridot has been associated with a variety of meanings and powers across different cultures and historical periods. In ancient Egypt, peridot was believed to have protective properties and was used in amulets to ward off evil spirits and nightmares. The gemstone was also associated with the sun and was used in jewelry to bring light and warmth to the wearer.
In medieval Europe, peridot was often used in religious and royal jewelry, where it was believed to have purifying and healing properties. The gemstone was also associated with love and friendship, and it was often given as a gift to strengthen relationships and promote harmony.

It is believed to help with digestive issues, skin problems, and other health concerns. It is also believed to promote overall wellness and vitality, making it a popular choice for those seeking to improve their physical health.
Care and Cleaning
Peridot is a relatively durable gemstone, but it still requires proper care to maintain its beauty and longevity. Because peridot has a hardness of 6.5 to 7 on the Mohs scale, it is susceptible to scratches and abrasions if not handled carefully. It is also sensitive to heat and chemicals, which can affect its color and luster.
To clean peridot jewelry, it is recommended to use a soft cloth and mild soap and water. Avoid using harsh chemicals or abrasive cleaners, as these can damage the gemstone. It is also important to avoid exposing peridot to high temperatures, as this can cause it to lose its color or become brittle.
When storing peridot jewelry, it is best to keep it in a soft, padded container to prevent scratches and damage. It is also a good idea to store peridot separately from other gemstones, as harder stones can scratch it. It is also important to avoid exposing peridot to direct sunlight for extended periods, as this can cause it to fade or lose its luster.
When wearing peridot jewelry, it is important to be mindful of the activities in which it is involved. While peridot is durable enough for everyday wear, it is still susceptible to damage if it is subjected to heavy impacts or rough handling. It is also a good idea to avoid wearing peridot jewelry when engaging in activities that involve exposure to harsh chemicals or extreme temperatures.
