Where to find Peridot
San Carlos Apache Reservation, Arizona, USA
One of the most significant sources of peridot, particularly large quantities of smaller stones. Found in basaltic lava flows.
Zabargad Island (St. John's Island), Red Sea, Egypt
Historically important source, known for producing large, fine-quality peridot. Associated with mantle peridotites.
Kashmir, Pakistan
Produces high-quality, vibrant green peridot, often found in association with serpentinite.
Myanmar (Burma)
Known for producing some of the finest, large peridot crystals, often found in alluvial deposits derived from peridotite intrusions.
China
Significant producer of peridot, particularly from Hebei and Jilin provinces, often found in basaltic rocks.
Vietnam
Emerging source of good quality peridot.
Norway
Historically known for peridot, particularly from the island of Almklovdalen.
Collecting tips
- Look in Volcanic Areas. Peridot is commonly found in basaltic lava flows and volcanic bombs. Search in areas with recent or ancient volcanic activity, especially where erosion has exposed the underlying rock.
- Check Ultramafic Rocks. Explore outcrops of peridotite, dunite, and serpentinite, which are primary host rocks for olivine. Peridot can occur as disseminated grains or larger crystals within these rocks.
- Examine Alluvial Deposits. Due to its relative hardness and resistance to weathering, peridot can be found in riverbeds and gravel deposits downstream from its primary source. Look for rounded, greenish pebbles.
- Identify by Color and Luster. Peridot's distinctive yellowish-green to pure green color and vitreous luster are key identifiers. Look for transparent to translucent grains or crystals.
- Consider Meteorite Hunting. While rare, peridot (olivine) is a major component of pallasite meteorites. If you are involved in meteorite hunting, keep an eye out for metallic meteorites with embedded green crystals.
Quick Check
