Peridot is a gem-quality variety of the mineral olivine. It belongs to the forsterite-fayalite mineral series. Some even refer to peridot as 'olivine', but when it comes to the gemstone, 'peridot' is the correct term. Peridot is an idiochromatic gem, meaning its color comes from the basic chemical composition of the mineral itself and not from minor traces of impurities. Thus, peridot is found only in green. In fact, peridot is one of the few gemstones available that can be found only in one color, although the shades of green may vary from light yellowish to dark brownish-green.
The name 'iolite' originates from the Greek word 'ios' meaning 'violet'. Iolite's strong pleochroism earned it the misleading trade name of 'water-sapphire', a name now obsolete. From one direction, iolite can appear sapphire-like blue and from another, it can appear as clear as water. Furthermore, from the top view down, it can appear light golden or honey-yellow in color. 'Dichroite' is another synonym for iolite in reference to its pleochroic ability; 'dichroite' is a Greek word which loosely translates as 'two-colored rock'. Iolite is also known as 'the Viking stone' because according to Norse legend, Vikings used iolite as a polarizing filter to help them find the sun on cloudy days. It is believed that the Vikings discovered iolite deposits throughout Norway and Greenland.
