Likely rough emerald (green beryl) in host rock

Beryl, Be₃Al₂Si₆O₁₈; green color typically caused by chromium and/or vanadium

AI-generated identification · may be incorrect

Dark green, glassy to vitreous crystals in a rough matrix; beryl has hexagonal crystal structure and Mohs hardness 7.5–8. The photo alone does not confirm the identification or show diagnostic crystal form clearly.

AI Estimated Value

A small, unverified rough specimen like this may be worth roughly $5–$50; value depends strongly on confirmed identity, crystal quality, and provenance.

AI estimate for general interest only — not an appraisal. Actual value depends on condition, provenance, and market demand. Verify with a professional before buying, selling, or insuring.

Physical properties

Formation & geological history

Emerald forms in chromium- or vanadium-bearing rocks where beryllium-rich fluids interact with them, commonly in metamorphic or hydrothermal settings. Deposits formed across varied geological ages.

Uses & applications

Gem-quality material is cut for jewelry; lower-grade emerald-bearing rock is collected as a mineral specimen.

Geological facts

Emerald is the green variety of beryl; inclusions and fractures are common and are often called jardin.

Field identification & locations

Look for a saturated green color and hexagonal prismatic crystals, but confirm with hardness, mineral tests, or a gemologist; common sources include Colombia, Zambia, Brazil, and Afghanistan.
