Fossilized Coral Jewelry in Sterling Silver
Fossilized coral jewelry features prehistoric coral colonies that mineralized over 20 to 30 million years ago. The original coral structure replaced by silica or calcite creates distinctive flower-like patterns called corallites.

Ancient Ocean Life Preserved in Wearable Form
Fossil coral forms when ancient coral beds become buried under sediment. Groundwater rich in silica or calcite gradually replaces the organic material while preserving the original skeletal structure. The result is a gemstone that records ocean life from the Miocene epoch. Major deposits come from Indonesia, Florida, and the Appalachian region of the United States. The characteristic patterns you see in fossilized coral jewelry reflect the actual coral species that lived millions of years ago. Petoskey stone from Michigan shows hexagonal patterns from Hexagonaria coral. Indonesian specimens display radial flower shapes in cream, grey, red, and brown tones. No two pieces share identical markings because each formed from different coral colonies under varying mineral conditions. SilverRush Style has offered natural stone jewelry since 2005. Our fossilized coral pieces use genuine specimens set in solid .925 sterling silver. The settings protect the stone while letting the ancient patterns remain visible. Add a piece of prehistoric ocean life to your collection today.Frequently Asked Questions
