Peridot is one of the few gemstones that come in only one color, with iron being the coloring agent. Olivine is a very abundant mineral, but gem-quality peridot is rather rare. Popular throughout history - from ancient Egypt to Baroque Europe - peridot is enjoying a much-deserved resurgence in popularity today. We carry this lovely stone in a variety of shapes, including round, oval, rondelle and natural chip.
