Physical properties

Formation & geological history

May be naturally rounded silica material later tumbled and polished, with iron-oxide staining producing the color; geological age and locality are indeterminate.

Uses & applications

Commonly sold as a pocket stone, craft material, or inexpensive lapidary specimen; usually has minimal commercial value.

Geological facts

The diffuse orange color is typical of hematite or limonite staining in quartz or chalcedony, though the image lacks diagnostic detail.

Field identification & locations

Test hardness against glass, inspect translucency and waxy texture, and use a streak test; quartz-family material should not scratch easily with a steel knife and typically leaves no colored streak. Common sources include Brazil, India, Madagascar, and the western United States.
