Peridot is admired for its fresh green color, ranging from bright lime and yellow-green to deeper olive shades. A touch of golden warmth gives it a distinctive appearance, while polished facets catch the light in lively flashes.
What Is Peridot?
Peridot is the gemstone variety of olivine, a mineral containing magnesium and iron. Much of it forms deep within the Earth and is carried to the surface through volcanic activity.
Sources include Pakistan, Myanmar, China, and the United States. The Red Sea island of Zabargad is one of its most important historical sources, with a long connection to peridot mining.
Olivine also occurs in some meteorites, although the peridot used in most jewelry comes from deposits here on Earth.
Color and Natural Characteristics
Iron is part of peridot’s chemical makeup and gives the gemstone its characteristic green. Differences in the mineral’s composition influence the shade, creating a range from lighter yellow-green to richer olive tones.
A stone’s size and cut also affect how its color appears. Smooth, polished cuts draw attention to the green itself, while facets add brightness and reflections as the gemstone moves.
Peridot has another interesting optical feature called double refraction. When looking through certain facets, the edges of facets on the other side of the stone can appear doubled.
How to Care for Peridot Jewelry
Peridot measures 6.5–7 on the Mohs hardness scale. It is well suited to jewelry, although its surface and edges should be protected from scratches and hard knocks.
After wearing, gently wipe the gemstone and metalwork with a soft cloth. For occasional cleaning, use mild soap and lukewarm water when suitable for the entire piece, then rinse carefully and dry thoroughly.
Avoid steam, ultrasonic cleaners, acidic cleaning products, and abrasives. Store each piece separately in a soft pouch or lined compartment to protect the stone’s polished surface and delicate metalwork.
Meaning and History
Peridot’s yellow-green color has inspired associations with light, warmth, and good fortune. Its bright appearance gives it a cheerful character, while its ancient sources connect it with a long history of personal adornment.
Zabargad, an island in the Red Sea, was an important source of peridot in the ancient world. Its history also reflects a time when gemstone names were used differently. The island’s green stones were associated with the name topaz, even though they were peridot rather than the mineral called topaz today.
Some medieval gems once described as emeralds were also later identified as peridot. These examples show how its rich green color was admired long before modern mineral identification clarified the differences between gemstones.
As one of August’s birthstones, peridot makes a thoughtful birthday gift. Whether chosen for a personal meaning or simply for its color, it brings a fresh green accent with a gentle golden warmth.
