Peridot properties at a glance

Geology & background

Forms deep in Earth's mantle and is brought to the surface by volcanic activity or tectonic processes.

Mined for over 3,500 years on the Egyptian island of Zabargad (St. John's Island).

How to identify Peridot

• Check whether the specimen's color and texture match typical Peridot examples.
• Photograph a fresh surface in natural light and avoid shadows, glare, or wet surfaces.
• Use hardness, streak, luster, grain size, and locality together; no single trait is enough for every specimen.

Where Peridot is found

Peridot is reported from multiple localities or geological settings. Exact locality should be verified from specimen provenance, maps, or field notes.

How much is Peridot worth?

Value depends on size, condition, color, crystal quality, locality, rarity, preparation, and provenance. Treat this as educational guidance, not an appraisal.

Common uses

• Jewelry
• Collector specimens

Interesting facts

• Found in meteorites and on Mars

Care & safety

Treat Peridot as a collector specimen unless hardness, cleavage, and fracture are confirmed.

Avoid inhaling dust. Do not cut, grind, or polish unknown specimens without eye protection and a properly rated respirator.
