Rainbow series: Peridot
Which piece was your favorite?
Peridot is one of the only gemstones formed deep within the Earth’s mantle rather than the crust. It is created under extreme heat and pressure, roughly 20 to 55 miles underground, and is transported to the surface in basalt rock by explosive volcanic eruptions. Some extremely rare peridot crystals have an extraterrestrial origin. They are occasionally found preserved inside pallasite meteorites (stony-iron meteorites) that have fallen to Earth.
Peridot is the gemological name for the mineral Olivine.
