Physical properties
Typically Mohs 6.5–7; translucent to opaque green with a vitreous luster and granular quartz structure. The curved, polished piece does not show diagnostic crystal faces; its exact stone identification from appearance alone is uncertain.
Formation & geological history
Forms as quartz-rich material containing reflective mica or other mineral inclusions, commonly in metamorphic environments; the quartz may be Precambrian, though this particular specimen’s age and source are unknown.
Uses & applications
Used for beads, cabochons, carvings, ornamental objects, and inexpensive jewelry.
Geological facts
Aventurine’s subtle shimmer is called aventurescence and comes from platy mineral inclusions; not all green aventurine exhibits strong sparkle.
Field identification & locations
Look for a green quartz body with tiny reflective flecks and hardness near 7; common sources include India, Brazil, and Russia. The broad polished shape suggests a carved or shaped specimen.
