Small blue-green mineral fragment, possibly apatite or beryl

Tentatively fluorapatite, Ca₅(PO₄)₃(F,Cl,OH), or beryl, Be₃Al₂Si₆O₁₈

AI-generated identification · may be incorrect

Tiny translucent blue-green fragment with vitreous luster and uneven fracture; apparent hardness is roughly 5–6.5 Mohs, but size and image quality prevent reliable determination of cleavage or specific gravity.

Physical properties

Formation & geological history

Such crystals form in hydrothermal veins, pegmatites, or metamorphic rocks; the specimen’s geological age and locality cannot be established from the image alone.

Uses & applications

Apatite is mainly a phosphate ore and collector mineral; blue beryl varieties may be gemstones, though this fragment is too small and rough for commercial jewelry.

Geological facts

Color and shape are insufficient for confident identification; apatite, beryl, turquoise, fluorite, and glass can look similar at this scale.

Field identification & locations

Confirm with hardness, streak, density, crystal habit, and locality information: apatite is commonly hexagonal and scratches glass weakly, while beryl is harder and typically forms six-sided prismatic crystals. Common sources include Brazil, Madagascar, Pakistan, Mexico, and the United States.
