Peridot is the Birthstone for the month of August.
In the United States, small stones can be found in the San Carlos Indian Reservation in Arizona. Peridot has also been found in some meteorites.
The peridot was regarded since ancient times as the symbol of the sun. The Greeks believed that it brought royal dignity upon its wearer. The largest stone is believed to be a 310 carat gem that belongs to the Smithsonian.
