Possible green tourmaline (small rough crystal fragment)

Possibly elbaite, Na(Li₁.₅Al₁.₅)Al₆(Si₆O₁₈)(BO₃)₃(OH)₄; identification is uncertain from the blurry image

AI-generated identification · may be incorrect

Tiny, dark green to yellow-green translucent fragment with a roughly prismatic form. Tourmaline is Mohs 7–7.5, vitreous, trigonal, and commonly has lengthwise striations; these details cannot be confirmed here.

AI Estimated Value

About $1–$10 for a tiny, unverified rough fragment; substantially more only if confirmed as gem-quality material.

Physical properties

Formation & geological history

If tourmaline, it likely crystallized in a lithium-rich pegmatite or related metamorphic rock; such deposits formed during ancient crustal activity. The photo does not establish its age or origin.

Uses & applications

Gem-quality transparent material is cut for jewelry; opaque or fractured pieces are collected, and tourmaline is also used in mineralogical research.

Geological facts

Tourmaline crystals commonly show strong color zoning and can be electrically polarized by heating or pressure.

Field identification & locations

A short, prismatic habit and green color are suggestive but not diagnostic; inspect for lengthwise grooves and test hardness only on an inconspicuous area. The reported southern Ethiopian location makes local identification important, but the image alone cannot establish that this is tourmaline.
