Peridots are transparent with a distinct oily luster. Peridot’s color can be described as yellow-green, green with a golden tone, olive or bottle green, deep chartreuse, or simply a brilliant light green. The proportion of iron present causes the shade and depth of the green of a peridot stone; the deeper the green, the smaller the amount of iron present. Peridot is one of a few gems that are not routinely treated. While it is not particularly brilliant (peridots have moderate to high brilliance), the richness of its color can be exceptional and is completely natural. Because of its rarity, peridot is not usually seen in its deeper pure green colors however newly discovered sources may change this. New sources include Arizona, Mexico, Oregon, Norway, Pakistan, Russia and Sri Lanka
