Physical properties

Formation & geological history

Likely weathered from quartz-rich rock and rounded during transport in a stream or beach setting; iron oxides produced the rusty color. The image cannot establish their geological age or exact source.

Uses & applications

Typically collected as curiosities or used in crafts and landscaping; these small pieces have little commercial or jewelry value.

Geological facts

Iron oxides such as hematite and goethite commonly stain otherwise colorless quartz red, orange, or brown.

Field identification & locations

Quartz is hard and scratches glass; look for a glassy fresh break and no cleavage to distinguish it from softer, similarly colored stones. Iron-stained quartz is widespread, but the exact location cannot be identified from the image.
