Peridot is one of the few gemstones that comes in only one color – green! However, it can be found in many different shades of green. . . all lighter and darker shades of green in the olivine family.
The variances in the green coloring depend on the amount of iron found in the stone. This iron content can either create a beautiful tinge of gold or make the stone appear to be more “lime green.”
Peridot is sometimes referred to as an “Evening Emerald” because under artificial light it glows as a brilliant green.
