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 jewellery at all price points.
Peridot to be worn in jewellery is most often set in yellow gold. This serves to neutralize any yellow tones within the stone and to emphasize the striking beauty of its green color. However, peridot paired with white metals is also desirable to many.
At a 6.5 on the Mohs hardness scale, peridot is softer than many other gems. Setting the stone in durable platinum may protect it from too much wear and tear through the years.
