Did you know one of the most radiant green gemstones on Earth also comes from the stars?
Peridot, the brilliant green gem variety of the mineral olivine, has fascinated scientists and gem lovers alike—not just for its glowing beauty, but because it’s quite literally out of this world. From ancient meteors to volcanic islands and Himalayan peaks, Peridot’s incredible journey through time and space makes it one of the most intriguing gemstones you can own.
Let’s explore the remarkable origins, history, and significance of this celestial gem.
Peridot in Outer Space: A Gift from the Cosmos
Unlike most gemstones formed solely on Earth, Peridot is one of the few known to arrive from space. Scientists have discovered olivine crystals inside meteorites that fell to Earth, offering evidence that Peridot-like minerals existed during the earliest formation of our solar system.
NASA’s Mars Reconnaissance Orbiter even detected olivine on Mars—specifically in a massive crater called Nili Fossae, believed to be over 3.6 billion years old. Olivine has also been found on the Moon and on comets, including Comet Wild 2 and Comet Tempel 1, where impact studies revealed traces of the mineral.
So if you’re wearing a Peridot, you’re not just wearing a piece of Earth—you’re carrying a connection to distant planets and ancient celestial bodies.
Forged in Fire: Peridot from the Earth’s Mantle
On Earth, Peridot is also geologically unique. It is one of only two gemstones formed deep in the Earth’s mantle (the other is diamond) and brought to the surface by volcanic eruptions or tectonic activity.
For thousands of years, the volcanic island of Zabargad, located in the Red Sea east of Egypt, was the world’s most significant source of Peridot. These gems were prized for their intense green hue and clarity and were often mistaken for emeralds.
More recently, Peridot was discovered in Pakistan’s Himalayas in 1994—at altitudes so high, the stones had been pushed to the surface not by lava, but by the collision of tectonic plates. It’s a reminder of Earth’s raw power: the top of Mount Everest itself contains marine limestone from an ancient seabed, uplifted by the same process.
A Gem of History and Legend
Peridot’s story doesn’t end with geology and astronomy—it has a rich cultural and historical legacy as well.
The Ancient Romans admired Peridot for its vibrant glow, calling it the “Evening Emerald” because its colour remained vivid by candlelight. In medieval Europe, Crusaders brought it back from the East to decorate cathedrals and religious objects.
Even earlier, there’s speculation that prehistoric humans may have discovered Peridot in meteorites, associating it with spiritual power and celestial origin. This ancient reverence may explain why Peridot was cherished in Ancient Egypt, where it symbolised protection against evil and was believed to harness the power of the sun.
Modern Appreciation: Why Peridot Still Dazzles Today
Whether you are a gem enthusiast, a stargazer, or someone seeking a unique piece of jewellery, Peridot offers both beauty and an incredible origin story.
It is the birthstone for August, representing strength, harmony, and vitality. Its vibrant lime-green hue complements both modern and vintage designs, making it a versatile and meaningful choice for any occasion.
And here’s a bonus: owning a Peridot means owning a gem that may have journeyed through space, endured the heat of volcanoes, or survived tectonic collisions over millions of years.
