The beautiful translucent bright green Peridot is the birthstone of the month of August. It is also known by the names Chrysolite and Olivine. The best examples come from Egypt and from the Pakistan-Afghanistan border region. The intensity of the colour of the stone depends upon the amount of iron it contains. Its chemical composition is magnesium iron silicate.
The origins of the name ‘Peridot’ are obscure; some authorities say that it is derived from the Greek word peridona which means ‘giving plenty’; others that it comes from the Arabic word faridat, meaning gem.
Schumann notes that there are historically important deposits on the Red Sea island of Zabargad, where it has been mined for over 3,500 years; it is also found in Burma (Myanmar), Queensland Australia, Brazil, China, Kenya, Tanzania, and Arizona. It has even been found in Norway.
