Physical properties

Formation & geological history

Quartz forms in igneous and hydrothermal settings over a wide range of geological ages; aventurine’s green color commonly comes from chromium-bearing mica. Bead cutting and polishing are human processing, not geological formation.

Uses & applications

Beads are used for jewelry and craftwork; natural quartz varieties are also collected and used decoratively.

Geological facts

The bracelet is shown inside packaging labeled PP 5, which identifies the bag’s plastic type, not the beads’ material.

Field identification & locations

Aventurine often shows a subtly glittery, mica-speckled surface; quartz beads are hard and resist scratching by a steel knife. Appearance alone cannot distinguish natural stones from dyed quartz or glass.
