Blue-green glassy mineral specimen, likely aquamarine or pale fluorite

Tentatively beryl (Be₃Al₂Si₆O₁₈), aquamarine variety; identification is uncertain from the photograph

AI-generated identification · may be incorrect

Translucent blue-green color with vitreous luster and irregular fracture; aquamarine is Mohs 7.5–8 with hexagonal crystals, while fluorite is Mohs 4 with cubic cleavage. The rounded, rough appearance may indicate a naturally weathered or tumbled piece.

Physical properties

Formation & geological history

Aquamarine forms in granitic pegmatites from late-stage hydrothermal fluids, commonly during Precambrian to Phanerozoic mountain-building events; fluorite forms in hydrothermal veins. Composition and locality require testing for confirmation.

Uses & applications

Aquamarine is used as a gemstone and collector mineral; fluorite is an industrial source of fluorine and a popular display mineral. This specimen appears suitable mainly for collecting unless transparency and clarity are high.

Geological facts

Aquamarine’s blue-green color commonly results from iron impurities. Similar-looking materials include blue-green calcite, glass, chrysoprase, and apatite.

Field identification & locations

Check hardness, specific gravity, cleavage, and crystal habit: aquamarine should scratch glass and show hexagonal prismatic form, whereas fluorite usually does not scratch glass and cleaves readily. Common aquamarine sources include Brazil, Pakistan, Nigeria, Madagascar, and Russia.
