This ring features a fossilized orthoceras set in sterling silver. Orthoceras are extinct marine cephalopods that lived hundreds of millions of years ago, and their fossilized shells preserve the internal chambered structure.

Details:

• Material: Fossilized orthoceras embedded in matrix
• Setting: Sterling silver
• Appearance: Polished fossil showing elongated, segmented shell structure in shades of black, white, and gray
• Formation: Orthoceras lived in ancient oceans; their shells fossilized in sedimentary rock over millions of years
• Physical Properties: Mohs hardness 3–4; smooth, polished surface
• Educational Value: Demonstrates fossilization, cephalopod anatomy, and sedimentary geological processes

This orthoceras ring combines paleontological significance with wearable design.
