Physical properties

Formation & geological history

Formed as silica-rich material deposited and altered in volcanic rocks, with iron oxides and other minerals producing its colors and patterns. The precise locality and age are not determinable from the image.

Uses & applications

Used for cabochons, carvings, polished spheres, and lapidary collections; not generally used as a major construction or industrial stone.

Geological facts

“Ocean jasper” is a trade name commonly associated with orbicular jasper from Madagascar; many visually similar jaspers occur elsewhere, so appearance alone does not establish provenance.

Field identification & locations

Identify by its opaque silica-rich body, hardness, and irregular orbicular or brecciated color patterns; verify with provenance or testing because polished jasper varieties can look alike.
