Gem-quality specimens of the mineral olivine are called peridot by gemmologists. Peridot has an olive-or bottle –green colour due to the presence of iron ,and a distinctive oily or greasy lustre .It has a high birefringence ,so doubling of the back facets can easily be seen in larger specimens when viewed from the front. Good-quality crystals are very rare.
OCCURRENCE: Peridot is found on St.John’s Island (Egypt ),in China ,Burma,Brazil ,Hawaii and Arizona (USA), Australia, South Africa, and Norway .
REMARK: The Crusaders brought peridot to Europe in the Middle Ages,transporting stones from St. John’s Island in the Red Sea, where it had been mined for over 3,500 years.
