Blue-green rough crystal, possibly aquamarine

Possibly beryl (Be₃Al₂Si₆O₁₈); the image is insufficient for a definitive identification

AI-generated identification · may be incorrect

Small translucent blue-green fragment with glassy luster and irregular fracture; hardness, crystal structure, and specific gravity cannot be confirmed from the photo. Aquamarine has Mohs hardness 7.5–8 and a hexagonal crystal structure.

AI Estimated Value

Approximately $1–$20 for a small, unverified rough fragment; value depends on confirmed identity, clarity, color, and weight.

Physical properties

Formation & geological history

If beryl, it typically crystallizes in granitic pegmatites or hydrothermal veins as magma cools; its age depends on the deposit, often millions to billions of years.

Uses & applications

Gem-quality aquamarine is cut for jewelry; less clear material is collected as mineral specimens. This fragment appears small and rough.

Geological facts

Blue-green beryl is called aquamarine, but similar-looking minerals and treated materials can be difficult to distinguish visually.

Field identification & locations

A hexagonal prism habit and hardness testing can help identify beryl, but laboratory gemological testing may be needed. Beryl occurs in pegmatites worldwide, including Brazil, Pakistan, and Madagascar.
