All facts and figures taken from the GIA

PERIDOT

Found in lava, meteorites, and deep in the earth’s mantle, yellow-green peridot is the extreme gem. The ancient Egyptians mined peridot on the Red Sea island of Zabargad, the source for many large fine peridots in the world’s museums. The Egyptians called it the “gem of the sun.” Today this gem is still prized for its restful yellowish green hues and long history. Large strongly-colored, examples can be spectacular, and attractive smaller gems are available for jewelry at all price points.
