Green aventurine and gray stone pendant

Likely green aventurine quartz (SiO₂), paired with a gray quartzite or feldspar-rich stone; exact identification requires testing

AI-generated identification · may be incorrect

The upper bead is pale green, translucent, waxy to vitreous, and appears tumbled; aventurine is quartz, Mohs hardness 6.5–7, with aventurescent mica or fuchsite inclusions. The lower gray bead is opaque to translucent with pale veining and likely has similar hardness.

Physical properties

Formation & geological history

Quartz-rich material forms in metamorphic or hydrothermal environments, generally during ancient mountain-building events; the beads are human-cut and polished. Geological age cannot be determined from the photograph.

Uses & applications

Used for inexpensive jewelry, carvings, and decorative objects; common polished beads typically have modest value.

Geological facts

Green aventurine is often marketed as “green jade,” but it is compositionally different from jadeite and nephrite. The apparent veining in the gray bead may indicate quartzite, feldspar, or another ornamental stone.

Field identification & locations

Confirm with a hardness test: quartz should scratch glass, while a steel knife generally will not scratch it; inspect under magnification for glittering mica. Common sources include India, Brazil, Russia, and China.
