Fossil Rings in Sterling Silver  

Ancient Organic Gemstones Set in .925 Silver Rings

Fossilized gemstones carry distinct visual patterns impossible to replicate. Ammonite fossils display the chambered spiral structure of extinct cephalopods, often with iridescent ammolite flash where aragonite layers remain intact. Petrified wood retains visible grain patterns and growth rings from ancient forests, now composed of chalcedony, quartz, or jasper minerals. Fossil coral shows the honeycomb-like structure of prehistoric reef organisms, ranging from cream to deep amber tones. These organic materials rate between 6.5 and 7 on the Mohs hardness scale after full mineralization, making them appropriate for ring wear with reasonable care. Our settings use solid .925 sterling silver, never plated metals, providing durable bezels that protect irregular fossil edges. Each ring ships from our US warehouse at no additional cost. Browse the collection to find fossil specimens with the coloration and pattern density that suits your preferences.
