Peridotite is a coarse-grained, dark-colored intrusive igneous rock, which consists of minerals such as pyroxene and olivine. It usually contains olivine as the primary mineral in addition to other mafic minerals, such as amphiboles and pyroxenes. It is very low in silica and high in magnesium.
Peridot gems can also be referred to as olivine, which is an iron and magnesium-rich mineral found on Earth. The word peridot is derived from the Arabic word Zabargad, which means peridot (Mineral Miners, 2007). Peridot also has another variety, or type, called chrysolite, which is yellow colored. The word chrysolite is Greek for yellow stone. A fair share of peridots are green though, which is how the mineral olivine got its name--from the color olive.
