With evidence going back to 1500 BC, legends have connected Peridot to the sun, believing that it brought energy and happiness to the owner.  They were also believed to ward off anxiety and help orators in their speeches.  For Peridot to exert its full powers as a talisman, it had to be set in gold, and when worn in this way, it was thought to dispel the terrors of the night.
The majority of gems are formed in the Earth’s crust. However, Peridot is formed much deeper, in the Earth’s mantle. The only other gemstones that are also found in the mantle are Diamonds. Even though Peridot forms in the upper mantle, it is still found 20 to 50 miles deep. Because it is so deep, the only way for peridot to naturally reach the surface is by tectonic plate activity or volcanoes. Some Peridot crystals have been found in rare pallasite meteorites that are 4.5 billion years old.
