Precious Stone Emerald
Emerald is a green variety of the mineral beryl.

to beryl includes aquamarine, Morganite,
and heliodor. Other colors of beryl are simply referred as to
by their color, such as red beryl.
The wonderful green color of emerald
is unparalleled in the gem history. Emerald's
precious green color is caused by its small amounts of chromium
and enhanced by traces of iron. Unlike other beryl’s, emeralds
are often contain inclusions and other flaws. These flaws
are not looked on as negative aspects for emerald like that they
would be for other gemstones.

the stone and are used to assure the purchaser
of a natural stone.
