Golden Beryl

The Gemstone Heliodor and Golden Beryl

Heliodor and Golden Beryl are the greenish-yellow to yellow varieties of Beryl. Beryl is best known for its famous gem varieties Emerald and Aquamarine, but other varieties such as Heliodor and Golden Beryl are also used as gemstones. In a strict sense, Heliodor and Golden Beryl are distinguished by their color, where Heliodor 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 Heliodor may also be used to describe light green, orange, and brown Beryl.
