Peridot is more than just a birthstone; it is a gem that encapsulates the essence of growth, renewal, and natural beauty. Unlike many other gemstones, peridot exists in only one color — a range of green tones that reflect the iron content in its composition. This unique characteristic, coupled with its historical significance and modern appeal, makes peridot a fascinating subject for gemstone enthusiasts and jewelry collectors alike.
History and Lore
The story of peridot is one that spans centuries, with roots in ancient civilizations that revered the stone for its beauty and protective qualities. The gemstone has been known by various names and has been found in historical artifacts from multiple cultures around the world.
Peridot was particularly valued in ancient Egypt, where it was referred to as the "gem of the sun." The stone was believed to have fallen from the heavens as fire from the sun, and it was often used in jewelry and amulets to ward off evil spirits and bring good fortune. During the Roman Empire, peridot was frequently used in ornate jewelry and was sometimes mistaken for emerald due to its similar green color.
In medieval Europe, peridot was a popular gemstone used in religious artifacts and royal regalia. Many of the "emeralds" found in medieval cathedral treasures have since been identified as peridot. This confusion highlights the gemstone’s striking similarity to more valuable green stones and underscores its historical appeal.
Peridot also holds a special place in Native American traditions. The Apache tribe, in particular, referred to peridot as the "stone of the night." They believed that the gemstone held the power of the sun and moon and was often used in rituals to promote healing and protection.
In modern times, peridot has been designated as the birthstone for August and is especially associated with those born on August 25th. Its vibrant color and positive symbolism make it a popular choice for jewelry and a meaningful token of personal significance.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, a group of minerals that are commonly found in igneous rocks. The gemstone forms in the Earth’s mantle and is brought to the surface through volcanic activity. It is also found in meteorites, where it is known as a mineral called "pallasite."
The chemical composition of peridot is (Mg,Fe)₂SiO₄, and its color is primarily due to the presence of iron. The more iron present in the stone, the deeper the green color. Peridot is known for its transparency and glassy luster, which enhances its visual appeal.
Peridot is found in various parts of the world, with major sources including:
- United States: Arizona and Hawaii are known for producing high-quality peridot. In Arizona, peridot is often found in basalt rock formations, while in Hawaii, it is found in volcanic deposits.
- Zambia: The East African country is a significant source of peridot, particularly in the form of large, high-quality stones.
- Brazil: Known for its rich deposits of various gemstones, Brazil also produces notable quantities of peridot.
- Russia: The Ural Mountains in Russia have been a source of peridot for centuries.
- Australia: Peridot is found in a number of locations across Australia, including in volcanic rock formations.
The unique geological conditions in which peridot forms contribute to its distinct color and clarity. The gemstone is often cut in a variety of styles, including brilliant cuts, oval cuts, and step cuts, depending on the desired aesthetic and the shape of the rough stone.
Gemological Properties
Peridot is a gemstone with a range of distinct physical and optical properties that make it a unique and valuable stone. Below is a detailed overview of its key gemological characteristics:
| Property | Description |
|---|---|
| Chemical Formula | (Mg,Fe)₂SiO₄ |
| Crystal System | Orthorhombic |
| Color | Yellow-green to olive green, depending on iron content |
| Hardness (Mohs Scale) | 6.5–7 |
| Refractive Index | 1.65–1.69 |
| Specific Gravity | 3.30–4.60 |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Cleavage | Perfect cleavage in two directions |
| Inclusion | Often contains small inclusions and may exhibit a "horsetail" inclusion pattern |
| Cut | Commonly cut in brilliant, oval, and step cuts |
| Treatments | Not typically treated, as peridot is already naturally beautiful and durable |
Peridot is relatively durable compared to many other gemstones, but it is not as hard as diamonds or sapphires. Its hardness on the Mohs scale ranges from 6.5 to 7, which means it can scratch glass but can also be scratched by harder materials such as quartz and topaz. This makes it suitable for most types of jewelry, but it should be handled with care to avoid damage.
The gemstone's refractive index is relatively high, which contributes to its brilliance and fire. However, peridot does not exhibit the same level of dispersion as diamonds or other high-dispersion gemstones. Instead, its beauty lies in its vibrant green color and the way it reflects light.
Peridot is also known for its perfect cleavage in two directions, which means it can be split along certain planes with relative ease. This characteristic requires careful handling during cutting and setting to prevent accidental damage.
Despite its potential for inclusions, peridot is generally considered to be a clean gemstone. Some inclusions are visible to the naked eye, while others require magnification to be seen. These inclusions are often considered to be part of the gemstone's charm and are not typically considered to detract from its value.
Symbolism and Metaphysical Beliefs
Peridot has long been associated with a range of positive attributes and metaphysical properties. It is considered to be a stone of strength, healing, and spiritual growth, and is often used in jewelry and talismans to promote well-being and protection.

Peridot is also associated with protection. It is believed to ward off negative energies and to create a protective barrier around the wearer. This makes it a popular choice for individuals who are seeking to protect themselves from harm or to create a sense of safety and security.
Overall, peridot is a gemstone that carries a rich array of symbolic meanings and metaphysical properties. Whether worn for its beauty, its spiritual significance, or its protective qualities, peridot is a gemstone that continues to be cherished for its unique and powerful attributes.
Care and Cleaning
To maintain the beauty and longevity of peridot gemstones, it is important to follow proper care and cleaning practices. Peridot has a hardness of 6.5–7 on the Mohs scale, which means it is relatively durable but not as hard as diamonds or sapphires. Therefore, it should be handled with care to avoid scratches and damage.
When cleaning peridot jewelry, it is recommended to use mild soap and warm water. A soft cloth or a soft-bristled brush can be used to gently clean the gemstone and remove any dirt or debris. It is important to avoid using harsh chemicals, abrasive materials, or ultrasonic cleaners, as these can damage the stone or affect its luster.
Peridot should also be stored separately from other gemstones to prevent scratches. It is best to store peridot in a soft pouch or a jewelry box to protect it from dust and physical damage. When wearing peridot jewelry, it is advisable to avoid wearing it during activities that may expose it to impact or abrasive surfaces.
Peridot is sensitive to sudden temperature changes, so it should be kept away from extreme heat or cold. It is also important to avoid exposing peridot to direct sunlight for prolonged periods, as this can cause the color to fade or become less vibrant.
By following these care and cleaning tips, peridot gemstones can be preserved for many years, ensuring that they continue to shine with their beautiful green brilliance.
