Raw emerald-bearing beryl (probable)

Beryl, Be₃Al₂Si₆O₁₈; green color from trace chromium and/or vanadium

AI-generated identification · may be incorrect

Hardness 7.5–8 Mohs; translucent to opaque green, vitreous to greasy luster, hexagonal crystal structure, and poor basal cleavage. The specimen appears embedded in a gray schist or mica-rich matrix, though image identification is not definitive.

AI Estimated Value

About $5–$30 for a common rough matrix specimen; $50–$500+ if it contains attractive translucent emerald, with gem-quality material potentially far higher.

Physical properties

Formation & geological history

Forms in hydrothermal veins and pegmatites during late-stage igneous activity, commonly in metamorphic rocks; deposits range from Precambrian to younger ages. Major sources include Colombia, Zambia, Brazil, Zimbabwe, Russia, and Afghanistan.

Uses & applications

Gem-quality material is cut as emerald; non-gem beryl is mainly a collector specimen. Emerald value depends strongly on color, clarity, transparency, treatment, and whether the green is chromium- or vanadium-related.

Geological facts

Emerald is the green gem variety of beryl, while aquamarine is blue beryl. Most natural emeralds contain inclusions, traditionally called a jardin (“garden”).

Field identification & locations

Look for a saturated green color, hexagonal prismatic crystals, hardness above glass, and mica-rich or pegmatitic matrix; fluorite or green quartz are possible alternatives. Professional testing for refractive index and chemistry is needed for confirmation.
