This pendant is both distinctive and unusual. It consists of a gorgeous faceted Green Amethyst gemstone paired with a Pyritized Ammonite. The Ammonite is an actual fossil. The organic matter of the fossil is replaced over the years with pyrite (fool’s gold). This is a naturally occurring process that takes millions of years to happen. Each one is totally unique and so awesome! This .925 Sterling Silver pendant measures approximately 3″ in length X 1 1/2″ wide, so this is a substantial piece. It’s just spectacular!
