Heliodor is a yellow, greenish yellow, or golden-yellow color of the mineral beryl. The yellowish colors of heliodor are usually caused by small amounts of iron within the mineral's crystal structure. The name "heliodor" is derived from two Greek words: helios "sun," and doron "gift." The "gift from the sun."
