Heliodor and Golden Beryl are the greenish-yellow to yellow varieties of Beryl. They are distinguished by their color, where Heliodor has a greenish-yellow hue, and Golden Beryl is a purer yellow. Golden Beryl is the most frequently used term in the gemstone market. Not surprisingly Heliodor gets its name from the Greek meaning "gift from the sun." Golden Beryl is said to make one sympathetic and increase sincerity.
