Olivine is a mineral belonging to the nesosilicates. Olivines may contain manganese instead of iron and magnesium. The name derives from the typical olive green color of this mineral, the term chrysolite is used as a synonym (when the stone appears transparent), while peridot is a dated term that indicates a transparent variety, in particular a gem, of the mineral.
