Emerald, the first stones were mined in the deserts of Egypt near the Red
Sea in what were known as Cleopatra's Mines. Egyptian Emerald mined
today are small and dark stones.
Sources for this gemstone are Colombia, Africa, and Brazil.
Emerald is a member of the Beryl mineral family, along with Aquamarine,
Golden Beryl, Goshenite, Bixbite and Morganite. The name for Emerald is
taken from the Greek smaragdos, meaning Green stone. The top color for
Emerald is a deep Green. Inclusions are generally accepted in Emeralds
since all but the rare few have visible inclusions of Mica, Pyrite or Calcite
or the "garden" type inclusions. Inclusions can be important in separating
natural from synthetic Emeralds and for identifying the country of origin.
TREATMENTS - Virtually
all Emerald on the market is included with some sort of surface-reaching
fractures and openings. The visibility of the inclusions is reduced by
filling them. Traditionally, oils (such as cedarwood oil) are used but
in time they tend to dry out thus making the inclusion more readily visible
again and the gem would require another oil bath. Today, natural
resin or wax type materials are preferred over the traditional oils, since
the resin or wax is a natural substance with more of an almost permanent
treatment life. Emerald
enhancement processes date back over 600 years, and oil, natural resin,
or wax type treatments are accepted trade practices that do not
adversely affect the performance and durability of the gemstone, so
you can expect all Emeralds will have some type of enhancement. There's
no need to worry when you see these enhancements disclosed.
CARE - Emeralds must be treated with care
to prevent chipping. Emerald jewelry should not be cleaned
in an ultrasonic or steam cleaner. We recommend
Ionic
Cleaners and/or warm, soapy water and a soft brush as the best way to clean
Emerald jewelry.
We only feature and offer Natural Emeralds.
