Geological Formation and Sources
Peridot is a mineral known as olivine, and it is formed deep within the Earth’s mantle. The gemstone is brought to the surface through volcanic activity, where it is found in specific geological formations. Peridot is unique in that it occurs in only one color—green—due to the presence of iron in its crystal structure. The intensity of the green color varies depending on the concentration of iron, with deeper, more vivid greens being the most prized.
Peridot is primarily sourced from volcanic rocks and lava flows, particularly in areas where the Earth's crust has been exposed to high heat and pressure. The gemstone is found in several countries around the world, including the United States, China, Pakistan, and various locations in Africa and South America. In the United States, peridot is mined in Arizona, where it is found in basaltic lava flows.
The process of extracting peridot involves locating and extracting the gemstone from its host rock. Once extracted, the rough peridot is cut and polished to enhance its natural beauty and brilliance. The gemstone's relatively soft hardness—ranging from 6.5 to 7 on the Mohs scale—means that it requires careful handling during the cutting and polishing process to avoid damage.
Gemological Properties
Peridot is a gemstone with distinct physical and optical properties that contribute to its beauty and desirability. The gemstone's color ranges from yellow-green to deep olive green, with the most valuable stones exhibiting a rich, saturated green hue. This color variation is due to the presence of iron, which is a key component of peridot's chemical composition.
Peridot has a hardness of 6.5 to 7 on the Mohs scale, which means it is relatively soft compared to other gemstones. This hardness level makes peridot suitable for use in jewelry, but it also means that the gemstone requires careful handling to prevent scratches and other forms of damage. Peridot is also known for its high refractive index, which gives it a bright, sparkling appearance. This refractive index contributes to the gemstone's brilliance and makes it an attractive choice for jewelry.
The chemical composition of peridot is (Mg,Fe)₂SiO₄, with the presence of magnesium and iron playing a crucial role in its coloration. The gemstone's structure is characterized by a silicate mineral composition, which is responsible for its durability and stability. Peridot is also known for its pleochroism, meaning it can display different colors when viewed from different angles. This property adds to the gemstone's visual appeal and makes it a unique choice for jewelry.
