By examining the properties and lore of Peridot, we uncover why it continues to be a cherished gemstone in both historical and modern contexts.
History and Lore
Peridot has a long and storied history, with evidence of its use dating back thousands of years. Ancient civilizations, including the Egyptians, Greeks, and Romans, revered Peridot for its beauty and believed it to possess protective and healing properties. The Egyptians referred to Peridot as the “gem of the sun” due to its golden-green hue, and they used it extensively in jewelry and amulets to ward off nightmares and negative energies.
Peridot was also found in the volcanic rocks of the Red Sea island of St. John, known in ancient times as Topazios, which is where the name “topaz” is believed to have originated. However, the gemstones found on this island were actually Peridot, leading to confusion with other green gemstones like emerald and topaz.
In medieval Europe, Peridot was often used in religious artifacts and was believed to have spiritual significance. One notable example is the Shrine of the Three Holy Kings in the Cologne Cathedral in Germany. This shrine was thought to be adorned with emeralds, but in fact, it contains Peridot. Some historians even speculate that Cleopatra’s famous emerald collection might have included Peridot as well, further emphasizing its importance in antiquity.
Peridot’s role as a birthstone for August 24th has been more recently established, but its historical significance as a gemstone of friendship and renewal continues to resonate today. Worn as a symbol of connection and positivity, Peridot remains a meaningful choice for those born on this date.
Geological Formation and Sources
Peridot is a naturally occurring gemstone formed deep within the Earth’s mantle. It is a member of the olivine mineral family, which is composed primarily of magnesium and iron silicate. The chemical formula for Peridot is (Mg,Fe)₂SiO₄, and the variation in its color—ranging from yellow-green to greenish-yellow—is due to the differing proportions of magnesium and iron in its composition.
Peridot is typically found in igneous rocks, particularly in basaltic and peridotite formations. It is also found in volcanic lava flows and in meteorites, making it one of the few gemstones that can be found both on Earth and in space. The presence of Peridot in meteorites has led some to believe that it is a “cosmic” gemstone, further enhancing its mystical allure.
The most notable sources of Peridot include the islands of Zabargad in the Red Sea, which were historically the primary source of this gemstone. Other significant sources of Peridot include the United States (particularly in Arizona and Hawaii), Brazil, China, Pakistan, and Madagascar. These locations are known for producing high-quality Peridot with a rich, vibrant color.
Peridot’s hardness on the Mohs scale is between 6.5 and 7, which means it is relatively durable but can still be scratched by harder materials. It is also sensitive to heat and sudden temperature changes, which can cause it to fracture. Understanding these properties is essential for both gemologists and jewelry owners to ensure proper care and preservation of Peridot gemstones.
Gemological Properties
Peridot is a unique gemstone with distinct gemological properties that set it apart from other gemstones. Some of its key characteristics include:
| Property | Description |
|---|---|
| Color | Yellow-green to greenish-yellow, with the most valuable stones displaying a vivid, pure green. |
| Hardness (Mohs Scale) | 6.5 to 7 |
| Chemical Composition | (Mg,Fe)₂SiO₄ |
| Crystal System | Orthorhombic |
| Refractive Index | 1.65 to 1.70 |
| Specific Gravity | 3.3 to 4.3 |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Inclusions | Common, including small crystals and fractures due to its formation in volcanic environments. |
One of the most notable features of Peridot is its color change under different lighting conditions. In daylight, Peridot appears more green, while under incandescent light, it can take on a yellowish hue. This phenomenon is due to the way light interacts with the iron content in the gemstone.
Peridot is also known for its pleochroism, a property where the gemstone exhibits different colors when viewed from different angles. In Peridot, this means that it may appear yellow in one direction and green in another, adding to its visual appeal.
The gemstone is typically cut into faceted shapes, such as brilliant or oval cuts, to enhance its brilliance and color. Peridot is also often cut into cabochons for use in beads and pendants, particularly in designs that emphasize its natural inclusions and patterns.
Symbolism and Metaphysical Beliefs
Peridot has been associated with various symbolic meanings and metaphysical properties throughout history. In ancient times, it was believed to have protective qualities, and it was often used in amulets and talismans to ward off negative energies and promote healing. The Egyptians, for example, believed that Peridot could protect against nightmares and bring dreams of the divine.
In modern gemstone lore, Peridot is associated with themes of friendship, growth, and renewal. It is believed to promote positivity, compassion, and balance, making it a powerful stone for those seeking emotional and spiritual harmony. Peridot is also thought to help release negative emotions and encourage a sense of calm and well-being.
The gemstone is often used in spiritual practices and meditation, as it is believed to help connect the wearer with the energy of the Earth and the Sun. Its vibrant green color is associated with the heart chakra, symbolizing love, healing, and emotional balance. For those born on August 24th, Peridot is considered a powerful symbol of their innate qualities, including compassion, wisdom, and unity.
Peridot is also believed to have physical healing properties, particularly in relation to the digestive system and metabolism. Some traditional healers use Peridot to help with ailments such as indigestion, nausea, and other stomach-related issues. However, it is important to note that these beliefs are part of traditional gemstone lore and should not be considered medical advice.

Avoid Contact with Harsh Chemicals: Peridot is sensitive to harsh chemicals, including household cleaners, perfumes, and lotions. To prevent damage, it is best to remove Peridot jewelry before using these products and to keep the gemstone away from acidic or abrasive substances.
