The birthstone for August 26 is peridot, a gemstone celebrated for its vibrant green color, rich historical significance, and symbolic meanings. Known as the "evening emerald" and the "gem of the sun," peridot has captivated people for millennia. This article delves into the gemological properties, historical lore, cultural symbolism, and practical care of peridot, offering a comprehensive look at why this gemstone remains a cherished choice for those born on August 26.

Introduction

Peridot is the primary birthstone for August 26, and it is part of a group of three official birthstones for the entire month of August, which also includes spinel and sardonyx. However, peridot stands out as the most historically significant and widely recognized of the three. It is a gem-quality variety of the mineral olivine and is unique in that it is one of the few gemstones that occurs in only one color—green. The shade of peridot can vary from a bright yellow-green to an olive or even a brownish-green, depending on the iron content within the stone. This variation in color is what makes each peridot distinctive, and it adds to the gem's appeal among gemstone enthusiasts and jewelry connoisseurs.

Beyond its aesthetic qualities, peridot is deeply rooted in history and mythology. Ancient cultures, including the Egyptians and medieval Europeans, revered peridot for its protective properties and its association with positive energy. It has also been linked to various metaphysical beliefs, with some attributing to it the power to ward off nightmares and bring happiness and strength to the wearer. In modern times, peridot is not only admired for its beauty but also appreciated for its affordability and versatility in jewelry design.

This article will explore the geological formation and sources of peridot, its historical use across different civilizations, its symbolism and metaphysical properties, and practical tips for caring for peridot jewelry. The goal is to provide a well-rounded understanding of this remarkable gemstone and why it holds a special place as the birthstone for those born on August 26.

History and Lore

Peridot has a long and storied history that spans thousands of years. It has been revered by various cultures for its beauty and believed protective powers. The gemstone is often referred to as the “evening emerald” due to its glowing green color, which is said to resemble the light of the sun. Ancient Egyptians called peridot the “gem of the sun,” believing it to be a powerful protector against evil spirits and bad luck.

In fact, the Egyptians were among the first to recognize the value of peridot. They mined it from the island of Zabargad, located in the Red Sea, and used it to craft jewelry and amulets. Egyptian priests wore peridot to ward off nightmares, and the gem was often placed under pillows for protection during sleep. This belief in peridot's ability to protect against negative forces persisted through the ages and influenced other cultures as well.

In medieval Europe, peridot was often confused with emerald due to its rich green hue. Many "emeralds" that were displayed in cathedral treasures have later been identified as peridots. This misidentification was due in part to the limited knowledge of gemology at the time and the similarity in color between the two stones. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral, for example, is adorned with peridot gems that were once believed to be emeralds.

Peridot also has a unique cosmic origin. It can be found not only in the Earth's mantle but also in meteorites that have traveled from outer space. This extraterrestrial connection adds another layer of intrigue to the gemstone’s history and enhances its mystique.

In more recent times, peridot has been recognized as the official birthstone for August since 1912. The American Gem Trade Association and Jewelers of America officially designated peridot as the primary August birthstone, a title it has held for over a century. This designation reflects not only the gem’s popularity but also its enduring appeal across generations.

Geological Formation and Sources

Peridot is a gem-quality variety of the mineral olivine, which is a silicate mineral composed primarily of magnesium and iron. The chemical formula for olivine is (Mg, Fe)₂SiO₄. The iron content in the mineral is what gives peridot its characteristic green color. The higher the iron content, the deeper the green hue becomes.

Peridot is formed under extreme conditions, typically in the Earth's mantle, where temperatures and pressures are high enough to create the necessary environment for the mineral to crystallize. As magma rises to the surface, peridot can be carried along with it, eventually cooling and solidifying into the gemstone we know today. This process explains why peridot is sometimes found in volcanic rock formations.

In addition to being formed on Earth, peridot can also be found in meteorites that have traveled from outer space. These extraterrestrial peridots are particularly rare and are considered scientific curiosities. Their presence in space rocks is due to the same geological processes that create peridot on Earth, albeit in a different environment.

The primary sources of peridot include countries such as the United States, Brazil, China, and Egypt. The most notable historical source is the island of Zabargad in the Red Sea, where the Egyptians mined peridot for thousands of years. Today, peridot is also found in other parts of the world, including Arizona in the United States, where it is mined from volcanic rock.

The availability of peridot in various parts of the world has contributed to its widespread use in jewelry. Unlike some gemstones that are rare and expensive, peridot is relatively abundant, making it more affordable and accessible to a wider audience. This accessibility has helped to cement peridot’s status as a popular choice for those born on August 26.

Gemological Properties

Peridot is a unique gemstone with several distinct gemological properties that make it stand out in the world of colored gemstones. Here are some of the key characteristics of peridot:

Color: Peridot is known for its green color, which is caused by the presence of iron in the mineral. The color can range from a bright yellow-green to an olive or brownish-green, depending on the iron content. This variation in color is one of the reasons why peridot is so versatile and appealing in jewelry.
Hardness: Peridot has a hardness of 6.5 to 7 on the Mohs scale, which means it is relatively durable but still requires care to avoid scratches and damage. While it is not as hard as diamonds or sapphires, it is still suitable for use in rings, necklaces, and other types of jewelry.
Luster: Peridot has a vitreous luster, which means it has a glassy, shiny appearance. This luster enhances the gem's beauty and makes it particularly attractive when polished.
Clarity: Peridot is typically included, meaning it often contains small inclusions or imperfections. These inclusions are usually not visible to the naked eye and do not detract from the gem's overall beauty. In fact, some gemologists consider these inclusions to be a sign of authenticity and natural origin.
Refractive Index: The refractive index of peridot ranges from 1.65 to 1.70, which means it has a moderate level of light refraction. This refractive index contributes to the gem's brilliance and sparkle, making it a desirable choice for jewelry.
Cleavage and Fracture: Peridot has a distinct cleavage, which means it can break along specific planes if struck with enough force. Because of this, it is important to handle peridot jewelry with care to avoid damage.
Chemical Composition: As mentioned earlier, peridot is a variety of the mineral olivine, which is composed of magnesium, iron, and silicon. The chemical formula for olivine is (Mg, Fe)₂SiO₄. The iron content in the mineral is what gives peridot its green color.
Cut: Peridot is commonly cut into various shapes, including round, oval, cushion, and emerald cuts. The cut of the gem can influence its overall appearance and how it interacts with light. A well-cut peridot will display excellent brilliance and color.
Carat Weight: Peridot is available in a wide range of carat weights, from small, delicate stones to larger, statement pieces. The carat weight of peridot is not as significant as it is for other gemstones, as the gem is relatively abundant and affordable.
Origin: As discussed earlier, peridot is found in various parts of the world, including the United States, Brazil, China, and Egypt. The most notable historical source is the island of Zabargad in the Red Sea, where the Egyptians mined peridot for thousands of years.
