310-Carat Peridot - The largest peridot in the world is housed at the Smithsonian in Washington, DC.
Peridot belongs to the forsterite-fayalite mineral series which is part of the olivine group. It is one of the idiochromatic gems, meaning its color comes from the basic chemical composition of the mineral itself, not from minor impurities, and therefore will only be found in shades of green. In fact peridot is one of the few semi-precious gemstones found in only one color.
