Peridot is the name given to the rare gem-quality specimens of the mineral olivine (because of its olive-green colour). The name probably derives from the Arabic word Faridad (gem). It has a virtuous and greasy luster and high birefringence (double refraction). Historically, it was first mined in the Egyptian island, Zabargad (St Johns) on the Red Sea. The Crusaders introduced peridot to Europe in the Middle Ages. It is also found in Australia, Burma, Brazil, China, USA and mostly recently, Pakistan. Jewellers refer it as the evening emerald since many royal treasures said to be emerald turned out to be peridot. It is the birthstone for August, and is believed to bring the wearer good health and fortune.
GEMS AND GEMOLOGY
Gemology has been a fascinating hobby of mine for over 20 years, reading up “Gemstones of the World” by Walter Schumann, attending practical classes on coloured gemstones, and visiting gem mining areas. I acquired some pieces, both priced and less well known, of various colours, shapes and cuts from gem-producing areas like Burma,Sri Lanka, Thailand, Cambodia etc. These have since grown to quite a collection.
Among the 63 gems species are: traditional gemstones - corundum(sapphire,ruby), beryl (emerald,aquamarine), fancy diamond; and others - spinel, chrysoberyl(cat's eye,alexandrite), tanzanite, garnet(tsavorite, spessartite,), tourmaline(rubellite,indocolite), zircon, topaz, quartz(amethyst,citrine), chalcedony(agate,chrysoprase), feldspar(moonstone,labradorite), kyanite, peridot, kunsite, scapolite, flourite and many other lesser known gemstones. (view complete list on blog archive on the right with traditional gemstones at the bottom. click on types of interest to you.)
