Peridot is a slightly golden
green gemstone which is assigned to the month
of August as a birthstone. It is also called Chrysolith
(derived from the Greek word “goldstone”)
and Olivin, because Peridot is the gemstone variety
of the Olivin mineral. Peridot is just an iron-magnesium-silicate,
and the depth of the green color depends on the
amount of iron contained. It is only available
in green, but can range from a yellow-green to
olive to brownish green. Peridot-Cat’s Eye
and Star-Peridot are valuable rare treasures.
Peridot is an ancient jewel, being found even
in Egyptian jewelry from the early second millennium
BC. It originally came from a small volcanic island
in the Red Sea, which has since been completely
exploited. More recently, it was discovered in
the Kashmir region, on a rough mountainside in
Pakistan of about 4,000m height. Stones from Pakistan
show a unique beauty and striking color, so though
it is very difficult to mine and transport this
stone, the demand for it makes it extremely popular
and thus there are no problems with delivery.
“Cashmere Peridots” are some of the
finest stones available, with a deep, lustrous
green.
Peridot has also been called the “Evening
Emerald” and is not affected by artificial
light. Peridot decorated many medieval treasures,
for instance the Cologne Cathedral. It was also
popular in the Baroque period.
The highest quality Peridots are found in Afghanistan
and Pakistan. They also exist in Myanmar, China,
the USA, Africa and Australia.
Peridot is not especially hard – it only
achieves about 6.5 to 7 on the Mohs´ scale.
It is an uncomplicated stone, but not a favorite
of cutters. The rough crystals can be devious
and are easy to break. The tensions existing inside
the crystal are often quite considerable. Peridot
is cut according to its crystal structure, usually
in classical table and facetted cuts, round, antique,
octagonal or oval shaped. Smaller crystals are
cut as calibrated stones; larger ones are shaped
by gemstone designers to fancy unique specimen
stones.
Peridot best complements a summer outfit and is
popular in jewelry series.
