An
aquamarine gemstone, Heliodor is completely flawless and yellow
variety of beryl with no eye-visible inclusions. It primarily occurs
in granite pegmatites and to a lesser extent in miarolitic cavities
in granites and in greisens. It derives its name from Greek word
meaning sun and gift in allusion to its color. Because of heliodor's
relatively high hardness and specific gravity, it is sometimes found
in eluvial and aluvial deposits. The color of heliodor is due to
trace amounts of iron impurities in the beryl structure.
Heliodor is said to improve communicative abilities and make one
compassionate and sympathetic towards others. Stabilizing the
heartbeat, heliodor helps in the treatment of disorders of the
stomach and small intestines, liver, spleen and pancreas. The
gemstone is found in the regions of Madagascar, Brazil, North
Carolina and California in the U.S., and in Middle Eastern countries
and Russia.
