Ancient marine fossils become graphic black-and-white jewelry components once they are cut and polished into cabochons. The straight shell sections and contrasting matrix create a pattern that feels almost geometric, even though every fossil formed naturally.

Use these Orthoceras fossil stones for wire wrapping, pendants, statement jewelry, mixed-media crafts, or small natural-history displays. “Orthoceras” is the common trade name used for these straight-shelled fossil cephalopods, which lived in ancient seas long before modern marine life.
