Peridot, the birthstone for August 10th, is a gemstone that stands out for its striking green hue and its long-standing association with prosperity, protection, and emotional well-being. As the traditional gem for the month of August, peridot has been treasured across cultures for thousands of years.

This article will explore the geological formation and global sources of peridot, its key gemological properties, its historical and cultural significance, and its role in metaphysical and emotional healing. Additionally, it will provide practical guidance on how to care for peridot jewelry, ensuring its beauty endures for generations.
History and Lore
Peridot has a long and fascinating history, with its earliest known use dating back over 3,500 years. The gemstone was first mined on the Red Sea island of Zabargad, an island now known as St. John’s Island. Ancient Egyptians referred to peridot as the “gem of the sun,” believing it to be a protective stone that could ward off nightmares and bring happiness and success to the wearer. It was also associated with the heart chakra and was thought to promote emotional balance and harmony.
One of the most intriguing aspects of peridot’s history is its misidentification with other gemstones. In medieval Europe, many peridots were mistaken for emeralds due to their similar green color. For example, the Shrine of the Three Holy Kings in the Cologne Cathedral in Germany was originally believed to contain emeralds, but it was later discovered that the gems were, in fact, peridots. Some historians even speculate that Cleopatra’s famous emerald collection may have been composed of peridot.
Peridot has also been found in meteorites, which makes it one of the few gemstones with an extraterrestrial origin. The mineral olivine, of which peridot is a variety, can form in the extreme conditions of space, further adding to its unique history.
Geological Formation and Sources
Peridot is a gem-quality variety of the mineral olivine, a magnesium iron silicate that forms under high-pressure and high-temperature conditions. It is typically found in igneous rocks, particularly in basalt and other volcanic rock formations. Peridot can also be found in meteorites, where it forms under the intense heat and pressure of space. This unique formation process gives peridot a distinct origin story compared to other gemstones.
The primary sources of peridot include:
- Zabargad (St. John’s Island): The oldest known source of peridot, located in the Red Sea.
- Arizona, USA: One of the most important modern sources, particularly in the Tucson area.
- Sri Lanka: Known for producing high-quality peridot.
- Brazil: A significant source of peridot, with deposits in several regions.
- Nigeria: Another notable source of the gemstone.
Peridot is typically found in a variety of shades of green, ranging from yellowish-green to deep olive-green. The color of peridot is influenced by its iron content; the higher the iron content, the more intense the green color.
Gemological Properties
Peridot has a set of distinct gemological properties that make it unique among gemstones. These properties include its hardness, refractive index, chemical composition, and optical characteristics.
- Hardness: Peridot has a hardness of 6.5 to 7 on the Mohs scale. This makes it relatively durable but not as hard as gems like diamond or corundum (ruby or sapphire). Because of its moderate hardness, peridot should be handled with care to avoid scratches or chips.
- Refractive Index: The refractive index of peridot ranges from 1.65 to 1.70, giving it a moderate level of brilliance and dispersion.
- Chemical Composition: Peridot is a silicate mineral with the chemical formula (Mg, Fe)₂SiO₄. Its color is due to the presence of iron in its crystal structure.
- Optical Properties: Peridot is singly refractive, meaning it does not exhibit double refraction. It also has a strong pleochroism, which means it can display different colors when viewed from different angles. This property can be seen in certain peridot specimens, which may appear more yellowish in one direction and more green in another.
- Inclusions: Peridot often contains small inclusions that are visible to the naked eye. These inclusions are typically not considered flaws but rather characteristics that add to the gemstone’s individuality.
One of the most notable features of peridot is its color. Unlike many other gemstones, peridot is found in only one color—green. While the exact shade may vary from yellowish-green to deep olive, peridot does not occur in other colors. This makes it one of the few gemstones with a single color variation.
Symbolism and Metaphysical Beliefs
Peridot has been associated with a wide range of symbolic and metaphysical beliefs across different cultures and time periods. In ancient times, it was believed to protect the wearer from nightmares and evil spirits. It was also associated with prosperity, success, and happiness. In modern times, peridot is still considered a stone of positivity and emotional healing.
Peridot is associated with the heart chakra and is believed to promote emotional balance, compassion, and harmony. It is also thought to help release negative emotions and encourage a sense of inner peace. Many people believe that peridot can aid in overcoming fear and anxiety, making it a valuable stone for emotional healing.
In some traditions, peridot is considered a stone of abundance and good fortune. It is believed to attract prosperity and help the wearer achieve their goals. This makes it a popular gemstone for those who seek success in business, career, or personal life.
Peridot is also associated with summer and the sun. It is believed to bring warmth, energy, and vitality to the wearer. This connection to the sun has led to its nickname “the gem of the sun.” In some cultures, peridot is worn during the summer months to harness its positive energy and promote well-being.
Care and Cleaning
Because peridot has a hardness of 6.5 to 7 on the Mohs scale, it is relatively durable but not as hard as some other gemstones. Therefore, it requires careful handling to avoid scratches and damage. When cleaning peridot jewelry, it is best to use a soft cloth and mild soap. Ultrasonic cleaners can be used, but care should be taken to ensure that the jewelry is not exposed to harsh chemicals or extreme temperatures.
To store peridot jewelry, it is recommended to keep it in a soft pouch or a lined jewelry box to prevent it from coming into contact with harder gemstones. Peridot should also be kept away from direct sunlight for extended periods, as prolonged exposure can cause it to fade or become discolored.
When wearing peridot jewelry, it is important to avoid activities that could cause impact or abrasion. While peridot is not as fragile as some other gemstones, it can still be damaged if subjected to rough handling.
