Tumbled pale green quartz (likely aventurine or common quartz)

Quartz, silicon dioxide (SiO₂); green color may result from fuchsite or chlorite inclusions

AI-generated identification · may be incorrect

Mohs hardness 7; translucent pale green-gray body, vitreous luster, cryptocrystalline to granular structure, and no visible cleavage. The rounded shape indicates tumbling or natural abrasion.

Physical properties

Mohs hardness 7; translucent pale green-gray body, vitreous luster, cryptocrystalline to granular structure, and no visible cleavage. The rounded shape indicates tumbling or natural abrasion.

Formation & geological history

Quartz forms in igneous, metamorphic, and hydrothermal environments over a wide range of geological ages; green aventurine commonly forms in quartz-rich veins with mica or chlorite inclusions.

Uses & applications

Used for inexpensive cabochons, beads, carvings, ornaments, and lapidary specimens; quartz is also important in glass, electronics, and abrasives.

Geological facts

The image cannot confirm whether the green color is from fuchsite, chlorite, or another inclusion, so a precise variety requires testing or magnification.

Field identification & locations

Common in quartz-rich gravels and hydrothermal veins worldwide, especially India, Brazil, Russia, and Africa. Confirm with a streak test (white), glass-scratching ability, and absence of strong cleavage.
