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!
