Heliodore and Golden Beryl are the greenish-yellow to yellow varieties of Beryl. In a strict sense, Heliodore and Golden Beryl are distinguished by their color, where Heliodore has a greenish-yellow hue, and Golden Beryl is a purer yellow or an orange-yellow. However, in both the mineral and gemstone trade, this distinction is not usually made and both terms are interchangeable, with the term Golden Beryl being the more frequently used term in the gemstone market. The term Heliodore may also be used to describe light green, orange, and brown Beryl.
