Emerald-like green beryl fragment

Beryl, Be₃Al₂Si₆O₁₈; green color typically from chromium or vanadium

AI-generated identification · may be incorrect

Small rough, translucent green crystal with vitreous luster and irregular fracture; beryl has Mohs hardness 7.5–8, hexagonal crystal structure, and specific gravity about 2.63–2.92. The image alone cannot confirm that it is emerald rather than another green mineral or glass.

Physical properties

Formation & geological history

Emerald forms in hydrothermal veins and metamorphic rocks where beryllium-rich fluids interact with chromium- or vanadium-bearing rocks, generally during Precambrian to younger mountain-building events. Other green beryl may form in granite pegmatites.

Uses & applications

Gem-quality material is cut for jewelry; lesser specimens are collector pieces. Value ranges from about $5–$50 for a tiny low-grade fragment to hundreds or thousands of dollars per carat for vivid, transparent natural emerald.

Geological facts

Natural emerald commonly contains fractures and inclusions, traditionally called jardin (“garden”). Its color is more diagnostic than transparency, but laboratory testing is required for reliable identification.

Field identification & locations

Common sources include Colombia, Zambia, Brazil, Afghanistan, and Pakistan; green beryl also occurs in pegmatites worldwide. Check for hexagonal crystal habit, hardness greater than glass, and natural inclusions, but do not scratch valuable material.
