The chrysolite is a very beautiful yellow-green gem which derives its name from two Greek words meaning "golden stone", by which name it is referred to by Pliny.

The stones are found in Egypt, Ceylon, and Brazil, and specimens have been found in meteorites and the lava of Vesuvius. The Peridot was much valued by the ancients, the name signifying in Arabic precious stone, and it was at one time considered of more value than the diamond.

During the Middle ages these stones were worn for foresight with regard to future events and for Divine inspiration and eloquence.
