The emerald gem was a favorite in pre-Columbian Mexico and Peru, where it was
cut in intricate designs. The treasure taken back to Spain by early explorers
included emeralds. Good emeralds are the most highly valued of gem stones.
India, Zimbabwe, and Australia are minor sources of the natural stones.
Synthetic emeralds are also manufactured in Germany, France, and the United
States. Emeralds do come with natural fissures and inclusions called "jardin"
which are sometimes oiled to help improve and enhance their visual
appearance. Therefore extreme care is needed in selection and care of your
keepsake. We suggest a commercial jewelry cleaner to soak your emerald item
(but only for a very short time), and use the enclosed cleaning brush to
remove all the grime and dirt, especially from underneath the stone. Wipe
with a soft jeweler's polishing cloth or soft cotton cloth. Minor scratches
can be repolished by a reputable lapidary.
It is generally thought of as green in color.
But look closer, and you'll discover subtle but important differences in
tones and hues. Some of the world's finest emeralds are described as
slightly bluish green in color and medium in tone. Pure green emeralds are
also highly desirable. Emerald is part of the mineral family called beryl.
If a gem is too light in tone it is no longer considered an emerald, but is
referred to as green bery/. Common in many emeralds are a wide variety of
internal characteristics or inclusions, often described collectively as a
garden. Many feel that this garden adds interest and individuality to an
emerald. Emeralds without these internal features are very rare and
valuable.
BIRTHSTONE
Emerald is the birthstone for May.
ORIGINS
Current key sources for emerald include Colombia, Brazil, Pakistan, Africa
and Russia.
TREATMENTS Almost all emeralds are routinely enhanced to improve
their appearance. Both natural and manmade fillers are commonly introduced
into the fissures in emerald to reduce their visibility. Often referred to
as oiling or infilling, similar enhancements have been done on emeralds for
thousands of years. These types of enhancements are not considered stable,
as fillers will come Out over time or when exposed to high heat.
CARE
Care should be excised when both wearing and cleaning emerald jewelry. The
internal features found in most emeralds make them very susceptible to sharp
blows and sudden temperature changes. Never clean an emerald with an
ultrasonic cleaning machine or a steam cleaner. You should not clean
emeralds with strong detergents or most commercial jewelry cleaners. The
safest and best way to clean a piece of jewelry containing emeralds is with
lukewarm water, a very mild soap and a soft brush. Be sure to rinse and dry
your jewelry thoroughly after cleaning.
