Green aventurine bead (likely)
Quartz, SiO₂, with green fuchsite inclusions
AI-generated identification · may be incorrectPolished, translucent-to-opaque pale green sphere with a glossy luster; quartz hardness is 7 Mohs and it has no cleavage. The small central hole and smooth finish indicate a drilled bead; the image does not confirm the material, and glass or synthetic stone can look similar.

Physical properties
Polished, translucent-to-opaque pale green sphere with a glossy luster; quartz hardness is 7 Mohs and it has no cleavage. The small central hole and smooth finish indicate a drilled bead; the image does not confirm the material, and glass or synthetic stone can look similar.
Formation & geological history
Natural aventurine forms when quartz crystallizes with reflective mica inclusions, typically in metamorphic or hydrothermal settings; its age depends on the deposit.
Uses & applications
Commonly used for beads, jewelry, and decorative carvings.
Geological facts
Natural green aventurine usually gets its color from fuchsite mica; glittery reflections are called aventurescence.
Field identification & locations
Look for subtle, irregular mica sparkle and natural variation rather than perfectly uniform color. Aventurine is found in deposits including India, Brazil, and Russia.
