ROCK TRIVIA: PERIDOT
Peridot is one of the few gemstones that occur in only one color, a yellow to olive green. The intensity and tint depends on how much iron is contained in the crystal structure. The most valued color is a dark olive-green. Peridot is a type of Olivine, which is a common mineral often found in lavas and in inclusions which lavas carry to the surface. Peridot can be also found in meteorites.
Olivine is an abundant mineral, but gem quality peridot is rare.
Peridot crystals have been found in some Pallasite meteorites. Pictured is
a piece of a Pallasite meteorite from Venezuela.
