About: Peridot Gemstone
Peridot is the green variety of the Olivine Group of minerals. Olivine is not an individual mineral but a group of minerals that includes Fayalitic, 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). Peridots colour can vary from pale to rich green (for which Peridot is famous) to brown. The considerable variation in shades of green to brown is Dependent on locality of origin and amount of ferrous iron. The ideal green Peridot has an iron content of about 12-15%. More iron results in a muddy colour. Very bright green Peridot may also contain traces of chromium.
