The name “Emerald” is derived from the
Greek smaragdos via the old French
esmeralde which simply means “green
gemstones”. Emerald is the green variety
of the beryl mineral family. Other
gemstone members of beryl family are
aquamarine, morganite, heliodor,
goshnite etc.
The very intense and powerful green
color of emerald is uncommon among
gemstones. This intense green color is
caused by small amount of chromium and
vanadium impurities in the stone.
Emerald is brittle and often contains
flaws otherwise known as inclusions.
Unlike other gemstones of beryl family,
inclusions are often tolerated in
emerald. Indeed, inclusions are
considered as one of the natural
characteristics of emerald. Emerald can
be found in Colombia, Brazil, Zambia,
Pakistan, Nigeria, India, Australia,
South Africa and Zimbabwe.
All our
gemstones are completely natural and
never treated in any form.

I have been delighted by the service
provided by Adron Gems. The emeralds
supplied are exactly as described, with
no exaggerated claims. They not only
supply the goods, but provide helpful
customer service; taking time to
understand your requirement and
providing additional descriptions. In my
dealings with Adron Gems I have found
them to be both honest and trustworthy.
I have no hesitation in recommending
their business to other customers –
