A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Heliodor is the yellow to yellow-green variety of beryl, colored primarily by iron. It shares the beryl family's key traits: Mohs hardness 7.5–8, good toughness, and typically high clarity in gem-quality material. Colors range from soft pastel yellow to rich golden hues and yellow-green tones; strongly saturated stones are less common and more desirable for fine jewelry.
