Physical properties

Formation & geological history

Agate forms as silica-rich fluids fill cavities in volcanic rocks and deposit chalcedony in layers; formation spans many geological ages. The beads have been cut and polished from natural material.

Uses & applications

Used for jewelry and ornamental crafts; agate is also used for small decorative objects and historically for precision components.

Geological facts

Agates are prized for their varied banding and inclusions, and each bead can show a different pattern.

Field identification & locations

Look for waxy luster, translucency at thin edges, and natural internal bands or inclusions; the image alone cannot confirm a particular agate variety. Common sources include Brazil, Uruguay, India, and the United States.
