Ammonite and Black Onyx Necklace

This Ammonite and Black Onyx Necklace brings together a fossil from ancient oceans and a striking natural mineral. The piece features a fossilized ammonite paired with polished black onyx, both set in sterling silver. Ammonites were spiral-shelled marine mollusks that lived during the Mesozoic era, and their shells were preserved through fossilization over millions of years. Black onyx is a variety of chalcedony, a microcrystalline form of quartz formed as silica-rich fluids deposit layers within rock cavities. Together, these natural elements highlight the intersection of paleontology and mineralogy in a wearable piece of earth science.
