925 sterling silver diamond cut ornate wispy design pendant with a gorgeous faceted solitaire heart peridot stone. The pendant measures 3/8 inch wide by 3/8 inch tall not including the bail. Peridot is the rare gem-quality variety of the common mineral olivine, which forms deep inside the Earth’s mantle and is brought to the surface by volcanoes. Rarely, peridot is also found inside meteorites. Peridot is the birthstone for August.
