The mineral beryl has many beautiful gem varieties: intense green emerald, sea blue aquamarine, golden yellow heliodor, rare red beryl, and pink to peach morganite. Beryl, in its pure form, is colorless. The rich hues of its gems are caused by a variety of impurity atoms that were incorporated in the crystals as they grew. The yellow glow of heliodor is due to impurities of iron. Heliodor gets its name from two Greek words meaning sun and gift. This deeply saturated heliodor is a natural slightly greenish-yellow color. The emerald cut gem weighs 275.31ct and is from the Ukraine.
