Peridot is a well-known and ancient gemstone, with jewelry pieces dating all the way back to the Pharaohs in Egypt. The gem variety of the mineral Olivine, it makes a lovely light green to olive-green gemstone. The intensity of color depends on the amount of iron present in a Peridot's chemical structure; the more iron it contains the deeper green it will be.
