Peridot the Green Gemstone

In this article we will discuss peridot. Peridot comes from extrusive igneous rock. These rocks were formed from the eruptions of volcanoes, with the lava finding its way to the surface by volcanic eruptions on the surface, or through fissures in the earth. Volcanic rocks formed from these eruptions. Among those formed were olivine basalt and it is in this rock that the peridot crystals formed.
