Peridot is a green gemstone that is as popular for jewelry today as it was in the past. It has been found in ruins of ancient Egypt and Greece and was often called the evening emerald by ancient Romans, who noticed that its green color shone even more vividly in lamplight, making it resemble deep green emeralds. Most ancient peridot probably came from the Red Sea island of St. Johns, which produced highly prized dark-green peridot.
