This awesome amethyst geode is a beautiful example of the lighter colored larger crystal formations and banding on the sides that can be found. They were formed millions of years ago in gas cavities from cooling lava. Iron present in the silica that filled the cavities is what gives these stones their purple color. This one has darker purple tips that graduate to a lighter pale purple. This amethyst measures about 3 inches tall and  around 3 inches wide. It may look small but it’s heavy and substantial and beautiful from all sides. Photographed in natural light and unedited for accuracy.
