About Peridot Gemstone

Peridot stone is the green variety of the Olivine Group of minerals. Olivine is not an individual mineral but a group of minerals that includes Fayalite, Forsterite, Liebenbergite, Tephroite and Laihunite. Fayalite (Mg2SiO4) is the iron rich member of the Fayalite – Forsterite mineral series, Forsterite (Fe2SiO4) is the magnesium rich member. Peridot (Mg2Fe2SiO4) is the green variety of Forsterite containing both Iron (Fe) and magnesium (Mg). Peridot’s color can vary from pale to rich green (for which Peridot is famous) to brown. The considerable variation in shades of green to brown is dependant on locality of origin and amount of ferrous iron. The ideal green Peridot stone has an iron content of about 12-15%. More iron results in a muddy color. Very bright green Peridot may also contain traces of chromium.

Peridot gemstone is not a recognized mineral name. It’s hard to believe that Peridot is the equivalent of a trade name, not a recognized mineral name since it is one of the most popular and well known gems in the world. Peridot has been a popular gem throughout history.
