925 sterling silver diamond cut heart stud earrings with an ornate filigree design and a gorgeous faceted solitaire round peridot stone. These earrings measure 1/2 inch wide by 1/2 inch tall each. 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.
