Peridot: Extraterrestrial
Gem
One gemstone is born in fire: peridot,
the volcanic gem. Small crystals of peridot are often found in the rocks created
by volcanoes and also can be found in meteors that fall to earth! A few samples
of extraterrestrial peridot have even been faceted into gems!
Peridot is the gem form of the mineral
olivine. Because the iron which creates the color is an integral part of its
structure, it is found only in green, ranging from a summery light yellowish
green to a 7-up bottle green.
Peridot is the birthstone for August.
Peridot was mined in ancient Egypt on
an island called Zeberget. Mining was done at night because legend said that
peridot could not be easily seen during the day. The island was infested with
serpents who made peridot mining a very dangerous occupation until one Pharoh
finally had them all driven into the sea.
The Romans called peridot "evening
emerald," since its green color did not darken at night but was still visible by
lamplight. Peridot later was also often used to decorate medieval churches,
probably carried back to Europe by the Crusaders. Large peridots, more than 200
carats in size, adorn the shrine of the three magi at the Cologne Cathedral.
Peridot had the power to drive away
evil spirits and the power was considered to be even more intense when the stone
was set in gold. Peridot was also said to strengthen the power of any medicine
drunk from goblets carved from the gemstone.
Today most peridot is mined by Native
Americans in Arizona on the San Carlos Reservation. Fine large peridot are found
in Myanmar (formerly Burma) and peridot is also mined in China and Sri Lanka.
In 1994, an exciting new deposit of
peridot was discovered in Pakistan, and these stones are among the finest ever
seen. The new mine is located 15,000 feet above sea level in the Nanga Parbat
region in the far west of the Himalaya Mountains in the Pakistanian part of
Kashmir. Beautiful large crystals of peridot were found, some that cut
magnificent large gemstones. One stone was more than 300 carats! This new
discovery, combined with fashion's passion for lime green, has revived interest
in peridot and increased the popularity of this gemstone.
Although peridot is treasured in Hawaii
as the goddess Pele's tears, almost all of the peridot sold in Hawaii today is
from Arizona, even though peridot is produced by Hawaii's volcanoes. The island
of Oahu even has beaches made out of olivine grains but unfortunately they are
much too small to cut into peridot!
