Peridot, the vivid green gemstone associated with the month of August, is a captivating mineral with a long and storied history. Known for its unique color and brilliance, peridot has been cherished across cultures and centuries, from ancient Egypt to modern jewelry design. In recent decades, peridot has also gained a special place in pop culture and collectibles, notably through its inclusion in the Barbie "Birthstone Collection" series. This article delves into the geological properties, historical significance, and cultural symbolism of peridot, as well as its representation in the collectible world through the Barbie dolls that feature the gemstone.
History and Lore of Peridot
Peridot has been treasured since antiquity. The ancient Egyptians referred to it as the "gem of the sun" and believed it was formed from the tears of Ra, the sun god. It was also highly valued in the Middle East and was often used in religious and decorative contexts. The name itself derives from the French word peridote, which comes from the Greek peridona, meaning "to give green."
The gemstone’s historical journey extends beyond Egypt and the Middle East. Sources indicate its discovery on the island of San Marco in the South Sea in 1815, where it was found within olivine deposits. This discovery added to the gemstone’s availability and contributed to its growing popularity.
Geological Formation and Sources
Peridot is formed deep within the Earth’s mantle and is brought to the surface through volcanic activity. It is a variety of the mineral olivine, a magnesium-iron silicate. The vibrant green color of peridot is due to the presence of iron.
While the provided sources do not detail specific modern mining locations beyond the historical San Marco find, the gemstone’s origin in volcanic rock suggests that it is found in areas with past volcanic activity.
Gemological Properties
Peridot is a remarkable gemstone with a number of unique properties that distinguish it from other stones. Its refractive index ranges from 1.650 to 1.690, and it has a vitreous luster that enhances its brilliance when cut and polished. Peridot is also known for its pleochroism, meaning it can exhibit different colors when viewed from different angles. While the dominant color is green, some stones may display hints of yellow or brown depending on the lighting.
In terms of hardness, peridot ranks at 6.5 to 7 on the Mohs scale, which means it is relatively durable but still susceptible to scratches and chips. This makes it suitable for everyday wear in jewelry but requires care when cleaning or storing. The most valuable peridot stones are those with a deep, rich green color and high clarity. These stones are often found in larger sizes, which adds to their desirability. Peridot is typically cut in a variety of shapes, including round, oval, and marquise, to showcase its color and brilliance.
Here's a table summarizing Peridot's key gemological properties:
| Property | Value |

| Chemical Formula | (Mg, Fe)₂SiO₄ |
| Refractive Index | 1.650 - 1.690 |
| Mohs Hardness | 6.5 - 7 |

Symbolism and Metaphysical Beliefs
Throughout history, peridot has been imbued with symbolic meaning. The ancient Egyptians believed it possessed healing powers and protected against nightmares. The association with the sun god Ra further cemented its connection to light, warmth, and vitality.
While the sources do not elaborate on specific metaphysical beliefs beyond the ancient Egyptian lore, the gemstone’s vibrant green color often symbolizes renewal, growth, and prosperity. This symbolism likely contributes to its popularity as a birthstone for August, a time often associated with the abundance of summer.
Peridot in the Barbie August Birthstone Collection
The inclusion of peridot in the 20th-century Barbie doll line highlights its enduring appeal. The August Birthstone Barbie dolls, specifically, have been released by Mattel in multiple editions since the early 2000s. These dolls, often dressed in green-themed attire and adorned with peridot jewelry, serve as both fashion accessories and collectibles. The dolls are part of a larger "Birthstone Collection" that celebrates each month’s respective gemstone, and peridot’s vibrant green hue makes it a standout in the series.
The Barbie August Birthstone Collection dolls are often accompanied by descriptions emphasizing the gemstone’s symbolic meaning and its connection to the month of August. These dolls, typically styled in elegant green dresses and paired with accessories like necklaces and bracelets, have become sought-after items for collectors. The collectible nature of these dolls underscores the cultural significance of peridot and its role in contemporary jewelry and fashion. The Zaana Jewelry "Barbie Girl Collection" also features peridot, demonstrating its continued presence in modern fashion and design.
Care and Cleaning
Given its hardness of 6.5 to 7 on the Mohs scale, peridot requires careful handling to avoid scratches and chips. It is best to clean peridot jewelry with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the gemstone. It is also advisable to store peridot jewelry separately from harder gemstones to prevent scratching.
