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.
