This Ammonite and Green Quartz Necklace pairs an ancient marine fossil with a vibrant natural mineral. The design features a fossilized ammonite alongside polished green quartz, both set in sterling silver. Ammonites were spiral-shelled marine mollusks that lived in Earth’s oceans during the Mesozoic era, and their shells became preserved through fossilization over millions of years. Green quartz is a form of silicon dioxide whose color comes from trace elements within the crystal structure. Together, these natural materials highlight both paleontology and mineral science in a distinctive piece of jewelry.
