Fossil Ammonite Quartz is uniformly beige and features fine texture, numerous light and dark veins, and a beige backdrop. In a tiny group of stones with fossil origins that also includes amber and coral, ammonite stands out for its opalescence and iridescence. Many various colour shades can be found in nature. The background is a dark beige in the Quartz forms version and is finely grainy in spots. Cleaning the surface immediately can go a long way in maintaining the countertop last longer. Though quartz does resist stain for a brief period.
