A golden or yellow variety of the mineral beryl, often used as a gemstone and named for its sun-colored appearance.
From Greek 'helios' (sun) and 'doron' (gift), literally meaning 'gift of the sun' because of its brilliant golden color resembling sunlight.
Heliodor gems are stunningly beautiful—ancient people literally called them 'sun gifts' because they gleam like captured sunlight, and now they're treasured by collectors!
